سلام
منم 5110 گرفتم

راستی اول در مورد فرق دو مد text و PDU یه کمی توضیح بدین تا روباه عزیز تستهاشو انجام میده .

گویا کار با PDU کمی سخت تر هست و گوشیهای جدید هم این مد را پشتیبانی می کنند .
مثلا من دستور تبدیل به مد Text رو به K750 و W810 و K800 فرستادم هر سه تاشون هم بهم ارور دادن و مدشئن تغییر نکرد .

دستورات ارسال اس ام اس هم توشون جواب نداد .
تهنا کاری که تونستم انجام بدم کارای ساده ای بود مثل :
میزان شارژ باطری
میزان آنتن
نام اپراتور شبکه
و بعضی چیزای دیگه

ولی 5110 رو نتونستم وصلش کنم به کامپیوتر . یکی دوجا هم دیتا شیتشو در آوردم اما بازم نشد و اصلا گوشی رو نشناخت .
یه چیز دیگه اینکه 5110 از فرمت Text هم پشتیبانی میکنه.

راستی برای ارتباط هم از هایپر ترمینال خود ویندوز استفاده کردم .



موفق باشید :smile:

Hack 4. Choose a Data Plan


With their comprehensive wireless support, Nokia phones are some of the most data-friendly gadgets around. If you're going to use your phone to connect to the Internet, make sure you've got the right data plan.

Your Nokia phone can connect you to the Internet in a lot of ways, but it's going to cost you. Before you commit to a costly data plan, you need to consider what you'll do with the phone. Will you send and receive email on the phone [Hack #60]? Do you plan to send a lot of camera phone pictures or video clips [Hack #69]? How about posting to your weblog [Hack #56]? And most important, will you use your Nokia phone to connect (tether) your laptop to the Internet [Hack #40]? It's possible for you to use your phone for a lot of what your computer can do, and yes, there are plenty of hotspots around for that data fix when you need it. But I think you'll give in and tether eventually just wait until the first time you open up your laptop and find no WiFi signal while your phone is showing five bars!

We will use the word tether even when referring to wireless methods of using your handset, such as the Bluetooth connection.






Data plans come in two flavors: metered and unlimited. With a metered plan, you get anywhere between 1 and 20 megabytes per month as a base allotment, and if you go over, you pay by the kilobyte. There are two types of unlimited plans: handset plans and really, honest, we-mean-it unlimited plans that let you use your phone as a wireless modem for your laptop or PDA.

1.4.1. Flavors of Cellular Data
The phone typically relies on the wireless operator's data network to connect to the Internet. The underlying wireless network technology is known as the data bearer of the mobile data. Here's a quick overview of the data bearers available from today's wireless service plans. Since the vast majority of Nokia devices are GSM-based, I focus the discussion on that technology.



GSM

The GSM network provides data access over the phone (data calls). It works in the same way as the dial-up modem on a PC. The benefit of this technology is that it is available everywhere you can get coverage. However, the drawbacks are the slow data rate (between 9.6 and 13.2 kbps) and the dedicated phone call for the connection. Since the call must be connected for the entire data session, it counts against your air time minutes. If you want to make a voice call, you must first disconnect the data call. All Nokia Series 40 and Series 60 devices support the GSM data bearer. GSM data is known as 2G (second generation).



GPRS

The GPRS network allows the phone to have direct access to the packet-switched data from the network. The phone does not need to dial any calls. This feature allows the phone to have always-on access to data without using up airtime minutes. GPRS is known as 2.5G (halfway between second and third generation). The data speed of 2.5G data bearers (between 20 and 40 kbps) is also faster than that of the 2G data bearers. All Nokia Series 40 and Series 60 devices support the GPRS data bearer.



EDGE

The EDGE network works much like the GPRS network, except that EDGE has a much faster data rate (up to 230 kbps). The EDGE network coverage is still limited. In the U.S., only AT&T Wireless (now part of Cingular Wireless) has national EDGE coverage. Only a handful of Nokia devices released after 2004 support the EDGE data bearer.



UMTS

The UMTS network is what's known as third-generation (3G) wireless networking technology. It offers broadband data speeds of around 384 bps. However, UMTS coverage is very limited. In the U.S., it is currently available in only a few selected cities. In addition, UMTS service plans can be very expensive. New Nokia phones such as the Nokia 6630 support UMTS.

Which data bearer is available to you depends on your wireless operator, your location, and your service plan. GPRS service should be available from all GSM operators wherever you have voice coverage. If your current service plan does not include any data service, you can call up your wireless operator and add it for an extra monthly fee. The data service is typically metered by the bandwidth you use in a billing period. Most operators also offer flat-fee subscriptions for unlimited data use. For instance, in the U.S., T-Mobile charges between $20 and $30 per month for its GPRS-only network, and Cingular charges $80 per month for its EDGE and GPRS networks.

Similar data bearers also exist in CDMA-based networks and are available on Nokia CDMA phones (Series 40). CDMA's data bearer is Single Carrier Radio Transmission Technology (1xRTT) and Single Carrier Evolution Data-Only (1xEV-DO). 1xRTT has typical rates of 70120 kbps, and 1xEV-DO has typical downstream speeds of 300500 kbps (with upstream speeds the same as those of 1xRTT).

1.4.2. Figure Out What You'll Need
This could be the hard part, but the good news is that you can just take a best guess. If the plan you select doesn't work out, most providers will let you change data plans midstream. Here are some considerations:



browsing Web

If you're going to browse the Web using your Nokia's built-in browser, chances are good that you won't use a lot of data, simply because that browser doesn't offer the rich graphical and multimedia content you get with a desktop browserin this case, it might be OK to go with a metered plan. However, if you use a third-party browser, it's possible you could end up using a lot of data, especially if you find yourself turning to your phone for web surfing [Hack #50] more than you do your laptop.



Email

If you plan to use your phone for sending and receiving email, this won't take up a huge amount of data (but see the next item). For the most part, email is text, and unless you're likely to use your phone to work with office documents [Hack #39], you probably won't move a lot of data with email. As such, you could get away with a metered data plan. If you're going to be sending and receiving lots of photos and video, get yourself an unlimited plan.



Tethering

If you plan to connect your laptop to your cell phone to get online, welcome to what some folks think is a gray area. Here's the problem: most of the low-priced unlimited data plans are intended for use with your phone only. However, it's technically possible to connect your laptop to your phone and get online. You will probably get away with this if you don't use a lot of data. However, anecdotes abound concerning people who claim to have received nastygrams from their cellular operator after using large amounts of data in this way. It's insanely simple for a cell provider to distinguish between traffic that originates from a phone and traffic that originates from a laptop. For example, every web browser transmits a User-Agent identifier every time you load a page: this is a dead giveaway.

Some providers will bill you differently based on your usage. AT&T Wireless (which was being absorbed into Cingular at the time of this writing) had a $24.99 monthly handset data plan, but vowed it would charge $1 per megabyte to users who tethered a laptop or PDA to their mobile phone. Furthermore, cell providers routinely, and sometimes temporarily, block access to certain ports (there have been reports of SSH, secure IMAP, and POP for email, and even secure HTTP being blocked), with the (misguided) rationale that most handset users don't need those ports.

If you plan to use your cell phone as your laptop or PDA's lifeline to the Internet and you don't want to risk unexpected overages or a service disconnection, go with an unlimited plan that explicitly supports tethering.



SMS and MMS

In theory, Short Message Service (SMS) and MMS come out of a different billing bucket than does Internet data, so the number of messages you send and receive shouldn't affect your choice of a data plan.

All those guidelines aside, the best thing to do is choose an unlimited data plan, if one is available (otherwise, pick the most generous metered plan). That way, if you don't use a lot of data, you can progressively downgrade each month. If you do use a lot of data, at least you won't get whacked with per-kilobyte charges.

1.4.3. Compare the Plans
Although wireless data might seem as though it's brand new, its pricing is settled, for the most part. Usually you'll pay around $5 to $10 per month for something that lets you do basic web surfing and email, and around $20 to $30 for more capabilities. So, if you're planning to use a lot of third-party network applications (such as instant messaging [Hack #66] and RSS readers [Hack #55]), you should go for the plan that gives you more. If you plan to use your phone as a wireless modem for your laptop [Hack #40], you should definitely choose an unlimited plan that supports tethering. Table 1-1 shows a few unlimited data plans that were current as of this writing.

If you think Table 1-1 looks very U.S.-centric, you're right. Although the U.S. lags behind in terms of the latest gizmos, it's a feeding frenzy for those who are determined to get all-you-can-eat data. In other parts of the world, metered data plans are more common. And the U.S. has its share of those as well. Table 1-2 shows some of these plans, from the low-end to the high-end offerings, and includes the range of charges you can expect if you go over the metered limit.

In most cases, you'll choose the data plan when you sign up for your voice service. However, most providers will let you add or change your data plan at any time. But before you make a change, ask the all-important questions: will this require me to agree to a contract extension, and will I be charged a termination or activation fee to make this kind of change? If you don't like the answer to either question, you should reconsider adding a data plan until it's time to renew your contract, or look into setting up a data plan on a separate line of service.

One problem you might run into is a customer service rep that is unfamiliar with the plan you want. The best thing you can do is make sure you know the name of the service. To find this out, visit the provider's web site. If you can't find the name of their data plan in five minutes, go through this simple exercise: add a phone to your shopping cart and then choose a voice planpreferably, the same one you are signed up for. The data plans available to you might depend on what level of voice service you have. For example, the price for T-Mobile's unlimited Internet plan is $19.99 with most voice plans, and $29.99 without a voice plan (or if you have a cheap plan).

At this point, the provider's web ordering system should offer you a data plan (you might need to click around for an optional services or features link), and you should write down the name of the service, call customer service, and ask them to add it to your plan.






Once you've selected a data plan, log into your provider's web site every day or so and keep an eye on your data usage as you goif you accidentally configure your email client to check mail every 30 seconds, you could be in for a surprise. The data total that shows up on the web site will probably be behind by 24 hours, perhaps more if you've used your data plan while roaming.

If you're on a metered plan and see yourself getting dangerously close to the limit, change plans right away. Although most providers will prorate the new plan after you change it, make sure you understand what exceptions are in place between the date you change the plan and the date your billing cycle resets. For example, suppose your billing cycle ends on the 28th of each month, and you are just shy of the 20MB limit on a metered plan when you switch to an unlimited plan on the 23rd of the month. You might think that you can use as much data as you want between the 23rd and 28th, but be sure to askwhen it comes to cellular billing, nothing is as simple as it appears.

Hack 10. Connect Your Phone to the Internet


Your mobile smartphone is as powerful as desktop computers were not too long ago. Not only that, but you can connect to the Internet with it. Combine these capabilities, and you've got a smart device that can connect you to email, the Web, and more.

The mobile Internet is a key part of the mobile lifestyle. Many of the cool features crammed into your Nokia phone are designed specially for Internet use. However, an October 2004 mobile survey conducted by Wacom Components suggests that more than half of the users polled thought that it was too difficult to access the Internet from their mobile phone, and hence they avoided the mobile Internet altogether.

If you're like these users and your phone is not yet connected to the Internet, you are not only missing out on a lot of fun, but you've also wasted your money by buying an expensive gadget that you don't use to its fullest extent!

Once you understand the key concepts involved, accessing the Internet from your Nokia phone becomes very easy. In this hack, I'll tell you all about it.

First I'll discuss the basic concepts of data access settings on a Nokia device. Then I'll cover how to determine the right setting values for your device and your network.

2.2.1. Data Access Settings
A Nokia device can access the Internet via several different data bearers [Hack #4], wireless operators, and proxy servers. Each valid combination of such parameters is known as a data access setting. A Nokia device can hold and manage multiple data access settings. You can assign a different setting for each application, or activate a different setting when you roam to a new wireless network. The Nokia Series 40 and Series 60 devices [Hack #2] manage data access settings in different manners.

On a Series 60 device, all data access settings are centrally managed as access points. You can define new access points or edit existing ones via the Tools Settings Connections Access Points menu (see Figure 2-1). You can assign a default access point to each network-aware application on the device via the application's own settings menu. For the Services application (your phone's web browser [Hack #50]), the default access point is specified via Options Settings Default access point. For the Messaging application, the default access point for MMS is specified via Options Settings Multimedia Messaging Access point in use, and the access points for email mailboxes [Hack #60] are specified via Options Settings E-mail Mailboxes (Name of your mailbox) Access point in use. For custom installed Java and Symbian applications, the default access point for each application is specified in the application manager [Hack #16] and [Hack #17]. If a network application does not have a default access point, you will be prompted to choose an access point when the application tries to connect to the network (see Figure 2-2).


Figure 2-1. The access point settings on a Nokia Series 60 phone





Figure 2-2. The device prompting you to choose an access point if no default access point is assigned for this application




The term access point in this section refers to a valid combination of access parameters on Nokia Series 60 devices. Do not confuse it with the term GPRS access point name, discussed later in this hack.






On a Series 40 device, each application manages its own set of data access settings. For instance, the MMS data connection settings are available under the Messages Message settings Multimedia msgs. Connection settings menu. The WAP and general Internet connection settings are available under the Services Settings Connection settings menu. The General Packet Radio Service (GPRS) modem connection settings are available under the Settings Connectivity GPRS GPRS modem settings menu. Figure 2-3 shows how to list and edit the access settings in the Services application.

The third-party Java games and applications on a Series 40 device share the connection settings from the Services application.






Now let's look at the available options in each data access setting (or connection setting) in more detail.

2.2.1.1 GSM dial-up modem.
If the data bearer is GSM Data, you have to specify the phone number of the operator's dial-up modem. You can skip this step if you are using the GPRS data bearer.

When an application accesses the Internet via GSM Data, the phone automatically dials the modem number to establish the data connection. You need to specify the type of data call in the configuration. The analog call modulates data over analog voice signals, which can be a slow and unreliable process. Most operators today use an ISDN connection for data calls (although the speed is still very limited). Notice here that since you are charged the regular rate for this call, you should use a local number if possible. For example, if you travel to a foreign country and still use your home country's service number, you might be charged an international fee for each minute of the call.


Figure 2-3. Managing the data access settings in the Services application on a Series 40 device




The data call times out after a certain period of inactivity to avoid excessive airtime usage. The default timeout is five minutes. You can configure this value via the Tools Settings Connections Data Call menu on a Series 60 device. However, you should disconnect the connection proactively to save airtime. If you use GSM Data to browse web pages, you should disconnect it as soon as you are done, or if you expect a long period of inactivity.

2.2.1.2 GPRS access point name.
If you use GPRS as the data bearer, there is no modem number to dial because the wireless network is already packet-switched and the data connection is "always on." But the wireless data network and the TCP/IP-based general Internet locate destination addresses and transport data packets differently. The wireless protocol stacks (e.g., TCP/IP Wireless Profile) are optimized for low bandwidth and high reliability. The wireless operator provides the interface between the GPRS network and the general Internet using a server known as the GPRS access point name (APN). In the wireless network, the APN is identified by a string name. You have to enter the APN in the setting for GPRS data bearers. Notice that the GPRS APN is a different concept from the "access point" on the phone. The latter refers to a valid combination of access settings, including the name of the GPRS APN.

Some operators require the phone to use a username and password pair to authenticate itself to access the GPRS APN (see Figure 2-4). In most cases, this is just a very simple username and password pair that is the same for all subscribers.


Figure 2-4. Configuring GPRS connection in a Nokia Series 60 device




2.2.1.3 Proxy servers.
The GPRS APN allows generic data packets to pass from the wireless network to the Internet and vice versa. But for many applications, the high-level data protocols on the wireless side are also different from those on the Internet side. Proxy servers (or gateway servers) are used to interface those application-level protocols. Two important types of proxy servers for Nokia devices are the MMS and WAP proxies:

The MMS proxy receives MMS messages from the phone and translates them to the standard Simple Mail Transport Protocol (SMTP) for Internet delivery. When an MMS message alert is delivered to a phone, the phone retrieves the message's multimedia content over the Internet via the MMS proxy.

The WAP proxy (a.k.a. WAP gateway) fetches Wireless Markup Language (WML) pages on the Internet using the HTTP protocol. It preprocesses WML pages, compresses them, and resolves WMLScripts according to the WAP specification. Then the WAP proxy feeds the processed pages to the phone browser using the WAP Session Protocol (WSP) over the wireless network.

On a Series 60 device, you can configure the proxy settings for an access point by choosing the Options Advanced settings menu from the access point configuration screen. You need to know the proxy server's IP address and service port number (see Figure 2-5 for MMS proxy settings on T-Mobile networks). Via the advanced settings menu, you can also enter a static IP address for your phone or DNS servers, if you are assigned one by the operator. The default values for the IP address and name servers are 0.0.0.0, which means that, once connected, the phone is to obtain those addresses automatically from the network.


Figure 2-5. Configuring the MMS proxy setting on a Nokia Series 60 device




As I mentioned, the MMS and WAP settings are configured within the Messages and Services applications, respectively, on Series 40 devices. Figure 2-6 shows the configuration of a WAP proxy on a Nokia 6230 device. It is accessed via the Services Settings Connection settings Edit active service settings menu. Select "Bearer settings" to change the APN and GPRS settings mentioned in the previous section.

2.2.2. Determine the Settings for Your Phone and Operator
Each wireless operator uses its own dial-up number, GPRS access point node, and proxy server configurations. If you purchased your phone directly from your wireless operator, you should have the appropriate Internet settings defined in the phone already. But in some cases, such as when buying a used phone or an unlocked phone, you will have to define the access points yourself. You can also call your wireless operator's customer service department to have them provision the phonethey will send Over The Air (OTA) messages to your phone that configure it automatically. You can also contact customer service to find out the exact settings you need in case you need to enter them manually (you will probably need to do this if you are using a phone that your wireless operator does not support).


Figure 2-6. Configuring the WAP proxy setting on a Nokia Series 40 device




The Nokia 6230 supports only GPRS-based connections. You have to use the Settings Connectivity GPRS GPRS modem menu settings to select the access points and GPRS APNs. To define a new access point, you can simply activate a blank access point and then edit the settings for the activated access point.






If your operator's customer support cannot help you with the settings (e.g., you have an "unsupported" phone!), you can search the Internet to find out what they are. For example, the web site http://www.opera.com/products/mobile/docs/connect/ lists GPRS APN names for many operators around the world; similarly, the web site http://www.filesaveas.com/gprs.html lists GPRS, WAP, and MMS settings for several operators in the United Kingdom.

2.2.3. Automatically Provision GPRS Settings
So far, I have covered the important concepts regarding access point settings. But finding the exact settings and then entering them by hand is still tedious and error prone. There is an easier way. You can use a web site maintained by Nokia to remotely configure your phone. The URL is http://www.nokiausa.com/support/settings/. You are asked to choose your region, operator, phone model, and type of service setting (e.g., WAP, Email, or MMS) you want to provision to your phone. Figure 2-7 shows the web-based configuration interface. After you type in your phone number and click OK, the web site sends a WAP service message to your phone's message Inbox. If you open that message, the new connection setting is automatically entered into your Access Points menu. As discussed earlier in this hack, your wireless operator can also provision your phone (but it might be faster to use web-based provisioning).


Figure 2-7. Using the Nokia web site to send MMS configuration settings as a short message to your phone




One limitation of this method is that you can only choose a phone model that is officially supported by your operator. If you have a new, unsupported phone, you can probably get away with choosing a similar older model. For example, settings for the Nokia 3650 phone work fine on the newer Nokia 6600 phone.

2.2.4. Share the Internet Connection from a Computer
If a Nokia Series 60 phone is connected to a computer via cable or Bluetooth [Hack #11], it can share the computer's network connection. With the computer acting as the proxy between the phone and the Internet, you can play with Internet applications on the phone without paying the GPRS subscription fee. However, the practical value of such a hack is questionable, as it limits the phone's mobility.

It is a complex process to set up both the correct routing tables on the computer and the correct access point on the phone. You have a better chance getting the computer proxy access point to work if you have working knowledge about TCP/IP networking.






Here are some resources and online tutorials that cover how to set up the computer network proxy for the phone:

Mika Raento has an excellent tutorial covering Windows and Linux computers with Nokia 7650 and 6600 phones. It is available at http://www.cs.helsinki.fi/u/mraento/symbian/bt-ap.html.

Rael Dornfest and James Duncan Davidson's book, Mac OS X Panther Hacks (O'Reilly, 2004), has a hack covering how to share a Mac computer's Internet connection to a Nokia Series 60 phone via Bluetooth. This hack is freely available in PDF format at http://www.oreilly.com/catalog/0596007183/chapter/hack55.pdf.

To avoid configuration headaches, you can buy a dedicated Bluetooth Internet access point device, such as PicoBlue, to provide Internet connections directly to Bluetooth devices. The Bluetooth Internet access point is preconfigured and replaces the proxy PC. It could save you a lot of trouble. But it is also pretty expensive ($500 or so).






A reverse of this hack is to use the phone's GPRS connection to provide Internet access to computers (e.g., your laptop while you are traveling). That is a much more useful hack and is covered in "Connect Your Computer to the Mobile Network" [Hack #40].

راستی اول در مورد فرق دو مد text و PDU یه کمی توضیح بدین تا روباه عزیز تستهاشو انجام میده .

گویا کار با PDU کمی سخت تر هست و گوشیهای جدید هم این مد را پشتیبانی می کنند .
مثلا من دستور تبدیل به مد Text رو به K750 و W810 و K800 فرستادم هر سه تاشون هم بهم ارور دادن و مدشئن تغییر نکرد .

دستورات ارسال اس ام اس هم توشون جواب نداد .
تهنا کاری که تونستم انجام بدم کارای ساده ای بود مثل :
میزان شارژ باطری
میزان آنتن
نام اپراتور شبکه
و بعضی چیزای دیگه

ولی 5110 رو نتونستم وصلش کنم به کامپیوتر . یکی دوجا هم دیتا شیتشو در آوردم اما بازم نشد و اصلا گوشی رو نشناخت .
یه چیز دیگه اینکه 5110 از فرمت Text هم پشتیبانی میکنه.

راستی برای ارتباط هم از هایپر ترمینال خود ویندوز استفاده کردم .



موفق باشید :smile:

آقا روباه
این دوستمون هم نتیجه من رو گرفته
هالا چی میگین

ببین چون 5110 کابل ارتباطی راحتی مثلا مثل 6600 نداره.
باید بازش کرد و از Rx , Tx نقشش حرکت کرد
