BLUETOOTH
Bluetooth is a short range radio link meant to replace the necessity of cables to connect portable and/or fixed electronic devices. The Bluetooth protocol uses a combination of packet and circuit switching to transmit data through variable hop frequency. Connectivity across a network is provided according to time slot division. It provides point-to-point or point-to-multipoint connection, creating links for between 2-8 devices (including the initiating Master/host and its Slave/s) to form a piconet. Multiple piconets that are linked together form a scatternet. A Master in one piconet can be a Slave in another, and vice versa, to form an inter-connected network. Dial-Up Networking, Fax, Headset, LAN Access, and SIM (Subscriber Identity Module) Access functionality all use serial port communication profiles and virtually emulate RS232 (or similar) serial cable port protocols.Ê A Bluetooth management application is necessary in each device to facilitate the serial port emulation. Radio Frequency Communications (RFCOMM) is used to transport user data, modem control signals and configuration commands.
When using a cellular device equipped for Bluetooth communications to transmit data over a cellular network, the Bluetooth link must be established as an initial protocol layer and the cellular network link is negotiated in a second protocol sequence through the cellular device. For example, when attempting to connect a Pocket PC device to the GPRS data network using a cellular phone as a negotiator via a Bluetooth link. The connection is initiated and controlled by the Pocket PC device, but dependent on the SIM functionality available through the cellular phone to negotiate and establish the connection to the cellular network. In this capacity, known as a SIM Access Profile, the cellular phone functions as a Server (or ÒaccepterÓ) while the Pocket PC device acts as a Client (or ÒinitiatorÓ). A Client may have access to only one Server with a SIM at any given time of active connection. Designation of a Client versus Server role is independent of the deviceÕs discover/discoverable status.
To ensure secure communication between the Client and Server devices, several conditions must be met. The Client and Server must be successfully Bonded (otherwise known as Paired) before setting up a SIM Access Profile or configuring the settings of a GPRS/GSM network connection. The SIM bearer (cellular phone) must be properly enabled to initiate authentication. The link between the Client and Server will be encrypted using the Bluetooth baseband and will be at a minimum of 64 bits. Each incident of authentication will be identified with a unique Passkey between the devices that must be in mutual agreement at the time of connection.
Bluetooth transceivers operate in the 2.4 GHz ISM (Industrial Scientific Medical) band. In a majority of the countries in the world this band includes 2.400-2.4835 GHz. Please note that products that implement a reduced frequency band will not work with those that implement the full frequency band. These products that are reduced in frequency (perhaps distributed in different countries), are generally intended for use in a single market. As such, devices developed and/or purchased in Europe and Asia (for example) may not be compatible for use with devices from the United States.
For more general information about Bluetooth development and technology, go to www.bluetooth.com, the official Bluetooth website. Select the link to Bluetooth technology & you to find links to Using Bluetooth technology, Products, and How it works. In the Using Bluetooth technology section, there is a link to view information about connecting a Mobile Phone with a Personal Computer. Here you can view links that include all currently supported and available devices that are applicable to your needs. This will be useful to verify the compatibility of your devices. You can find specific information about the technical details and requirements of modem data transmission using cellular technology with Bluetooth by proceeding to the Developer Information section and viewing the SIM Access Profile and v.1.1 Profiles documentation.

GENERAL DIAGNOSTICS WITH BLUETOOTH
* Make sure that your Bluetooth devices are compatible.
* Your operating system should be current on all applicable software, driver, and firmware updates.
* Verify that the Bluetooth functionality in both devices is turned ÒOnÓ.
* Verify that the devices are currently bonded/ paired. This can often be difficult to assess with the Nokia 6310i. The phone may not show the devices as ÒActiveÓ, but the Bluetooth Manager will display that the devices are paired/bonded. Often the phone will display a Disconnected message. Disregard this message and continue with the instructions in the setup guide.
* Ensure that the Bluetooth Dialup Modem is selected in the Connections (for Pocket PC devices), System Preferences/ Network (in Mac OS X), or Dial-Up Networking properties (in Microsoft Windows OS).
* It may be necessary to attempt to connect multiple times to establish a GSM/GPRS connection. Do not be discouraged if you receive a connection error or receive a Disconnected message on your cellular phone. Due to interference or early product development, it may take several attempts to push the connection through all layers of the Bluetooth service and protocol stack. It is also possible, as is seen with the Nokia 6310i, for a Disconnect message to be given while transfer protocol layers of communication are still recognized and active. In this case, a temporary minor error (Òdata not availableÓ or Òcard not accessibleÓ) is the cause as the Client device attempts to initialize and access the SIM for data packet transfer.
* Verify that you are not in the presence of equipment that may be interfering on the same (or possibly overlapping) radio frequency as your Bluetooth communication. This includes medical equipment, wireless 802.11 connectivity devices, other Bluetooth enabled cellular phones, airport communications, amongst other factors.
* It may be necessary on some devices to alternate in the bonding/pairing process between setting the phone in Discover versus Discoverable mode, as is sometimes the case with the Sony Ericsson T68i.
* Verify that your devices are fully charged.
* Verify that you have GSM/GPRS coverage available at your location and that your wireless account is properly provisioned for data transmission with a modem over the network.
* Check that your connection is using the correct Dialing Location properties and profile. For a GPRS connection, this should follow the instructions to include the letter G in each of the three dialing location fields of the Dialing Patterns specifications as well as verification that the phone number to be dialed is *99# and that the Area Code and Country Code fields are not included in your connection.
Alternative methods of Pairing/Bonding for the Nokia 6310i and iPAQ 3800/3900 series device with Pocket PC 2002 Operating System
If you are experiencing problems due to interference, or if your signal strength is not very strong, modifying the serial port connection may allow you to connect to the GPRS network.
* Open the Bluetooth Manager application on your Pocket PC device.
* Verify that the Bluetooth on your handset is currently On. (You may want to check the power level on your devices.)
* If your Nokia 6310i is not seen as an available device, tap on Search and proceed to locate it and Save it to a group. Otherwise, tap on the Nokia 6310i icon.
* Tap on Actions.
* Select Set as Bluetooth Dialup Modem.
* Tap Actions again.
* Select Connect to COM 1.
* Press Accept on the phone to connect with the Pocket PC device.
* Enter a unique Passcode onto your handset.
* You will have 10 seconds to enter the same Passcode/PIN code onto your Pocket PC device.
* Your phone will notify you that you are connected. You can verify this by scrolling through the Bluetooth menu on your handset and selecting View active device.
* You will have 3 minutes to proceed before your Bluetooth session will time out.
* Proceed to connect using the usual methods outlined in the setup guide.
* You will be notified that the Serial style= style=Port style=connection was terminated . Tap OK and continue anyway. It may take several attempts to get the Bluetooth stack to respond.
* Press Accept to connect to the phone once more.
* The phone will now notify you that a GPRS connection is in progress.
The following method may also be useful if the bonding appears to be unstable and multiple attempts to connect through the Connection Settings fail:
* Open the Bluetooth Manager application on your Pocket PC device.
* On the phone, scroll to select Bluetooth from the main menu, then select Bluetooth and select Off.
* Turn your phone off, then on again to fully reset its Bluetooth protocol stack.
* On the Pocket PC device you should see the Nokia 6310i listed. Tap to select it.
* Tap on Actions.
* Select Remove bond with this device.
* Tap on Actions again.
* Select Remove this device.
* Tap Yes when asked if you want to remove it from all groups.
* Close all open windows on your Pocket PC device and tap on the Bluetooth icon on the lower left corner of your screen.
* Select Turn radio off.
* Soft reset your device according to manufacturerÕs instructions.
* Tap on the Bluetooth icon on the lower right corner of your screen again and select Turn radio on.
* Turn the phone back on, scroll to Bluetooth from the main menu, then select Bluetooth and select On.
* Open the Bluetooth Manager application.
* If you do not see your device listed, tap on Search.
* Tick the box to select your phone, choose a group and select Save.
* Tap OK.
* Tap on the Nokia 6310i icon.
* Tap on Actions.
* Select Create bond with this device.
* Enter a unique PIN code.
* Press Accept on the phone when prompted to Pair with the Pocket PC device.
* Enter the Passcode/PIN code. You will have 10 seconds to complete this task. (If you receive a Disconnected message on the phone, continue anyway.)
* Proceed to set up your connection as usual through your Connection Settings.
* If you are not connected the first time, tap Connect to try again immediately after you receive the Disconnected message on the phone. It may take several attempts to get the Bluetooth stack to respond.
* Press Accept on the phone to accept the connection.
* The phone will indicate that a GPRS connection is in progress.
The processes for troubleshooting Bluetooth in a Windows environment are very similar to those of Pocket PC devices.
* In the Bluetooth Manager application, proceed to click on the Nokia 6310i and select Unpair device, then proceed to turn the Bluetooth radio Off on the computer and on your phone. Reset both devices, then try again. This should clear any temporary problems in the Bluetooth service and protocol stacks.
* It may be necessary to attempt to establish your GSM/GPRRS connection multiple times before you will actually be able to transmit data over the cellular network.
* Verify adequate power level on each device.
* Resolve any issues that may exist with your cellular account or wireless coverage in your location.
* Other wireless electronic devices that operate in (or near) the Industrial, Scientific, and Medical bandwidth may provide significant interference. These include other cellular phones, 802.11 devices, medical equipment, airport communications, amongst other factors.
* You must select secure encryption to be used when creating the bond with your devices in the Bluetooth Manager.
USEFUL AT COMMANDS
When GPRS doesn't appear to be working, or you just want to check that all is well, hopefully the following will prove useful:
Check the phone
Verify that GPRS is currently available in your location and that your cellular account is properly enabled for data transmission over the network using your device as a modem.
If all appears well on the phone, head to HyperTerminal or your equivalent Terminal application and try some of the following style=to further query the status of your ability to communicate with the network:
at+cgatt?
If a value of '1' is returned, then we have GPRS attached. If the value is '0', then GPRS is currently deactivated (i.e. the service is either down or the user is not currently provisioned).
at+cgatt=? will return the supported values for the command
at+cgatt=1 will attempt to attach to the GPRS network
at+cgdcont?
This will allow you to check that the Access Point Name (APN) has been set correctly.
A typical response will look something like this:
+CGDCONT:1,"IP","proxy"
If the APN is set incorrectly for the AT&T Wireless GPRS service, enter the following:
at+cgdcont=1,"IP","proxy"
at+cops?
This will return the identity of the network operator.
at+cgreg?
This will return the network registration status.Ê One of the following values should be returned:
0 - not registered, not searching
1 - registered, home network
2 - not registered, searching
3 - registration denied by network
4 - unknown
