    Question 8703e, OS4.2, and Bluetooth DUN

    Advertisement



    I just upgraded my Sprint 8703e to the VZW 4.2 software that just came out.

    The feature I've been waiting for was bluetooth Dial-up-Networking (DUN), so that I might be able to tether to a Mac and Linux (and even Windows without having to install the Desktop Manager software).

    I can pair with a computer (any kind) and the virtual COM port is created by the DUN component. I can open a terminal program and connect to this serial port. When I connect, I get "AT" response from the blackberry, but nothing further.

    I was under the impression that the DUN feature emulates a limited AT command set modem, and the "AT" response seems to confirm this. However, when I send ATZ, ATDT#777, or any other AT command, there is no response at all.

    Has anyone been successful in using plain old DUN services with 4.2.1?

    I have used "plain old DUN", both USB and Bluetooth, with a VZW 8703e and the new OS v4.2.1.106 on Windows XP -- I have used the VZAccess Manager for USB connections with OS 4.1 (still works with v4.2), but Bluetooth has not been an option in the past. I am not sure that ATDT commands will work as there is no dialtone. Just create an DUN connection, and select the Bluetooth com port that you have created as the modem. A simple test that you can perform in Windows XP is to open the Phone and Modem Options control panel. Select the Modems tab. Select the Bluetooth modem (mine shows as "Standard Modem over Bluetooth link" attached to COM11).Select the Properties button. Select the Diagnostics tab. Select the Query Modem button. You should see a series of AT commands verifying the connection from the computer to the BlackBerry (aka modem). Hope this helps...

    Here is the modem log from the Query Modem command (I x'ed out ESN):

    ATQ0V1E0 - OK
    AT+GMM - 8703e
    AT+FCLASS=? - 0,2.0
    AT#CLS=? - COMMAND NOT SUPPORTED
    AT+GCI? - COMMAND NOT SUPPORTED

    Okay. I guess I'm having other issues...

    On my desktop with a Kensington USB Bluetooth EDR adapter, which installs the widcomm bluetooth stack, this works fine.

    On a Dell laptop with Toshiba bluetooth stack, no go...

    What Dell Bluetooth adapter do you have? I am successfully using the Dell TrueMobile 300 internal adapter successfully with the standard XP drivers (not Dell-specific) on my Dell notebook.

    I have a Dell Latitude D820 with the Dell 350 Internal Bluetooth module.

    I get the same no-response action from both Linux and Windows XP on this same hardware.

    Okay. When I set up the laptop initially, I just installed all the Dell drivers, which included the Toshiba bluetooth stack.

    I have now removed the Toshiba bluetooth stack and am using the Windows XP driver and it works perfectly.

    Now to see what's up with Linux.
