    Problem with bluetooth interface with nokia 2700

    Hi all,

    I have got two problems!
    Problem 1
    I am trying to connect to Nokia 2700 using A7 EB101 Bluetooth module running from a PC(Hyperterminal)!
    When the bluetooth connection is being established between PC and Nokia 2700,the bluetooth module
    will be in data mode! I need to send the AT commands to control the modem of the mobile!
    The bluetooth connection gets disconnected even before i send the data ie, when i just type anything in the hyperterminal, the bluetooth connectivity gets lost! This doesnt happen when i use a sony ericsson mobile!
    Can anybody help me regarding this?

    am trying to establish a GPRS connection through bluetooth enabled
    phone using a bluetooth application running on java!

    Re: Problem with bluetooth interface with nokia 2700

    Hello world,
    I think i was able to get a partial solution for problem two
    When i try to connect to internet through GPRS using my mobile Nokia 2700 classic,
    I do see a small icon "E"(encircled) on the top! This indicates that GPRS connection was successful!

    After giving the following set of commands through bluetooth interface from PC(running java application),
    I saw the same "E" icon encircled! Does this mean that the GPRS connection was successful?
    I tried to get the IP assigned by the network,but i got error as response from the mobile!

    Is it possible to give AT commands to establish TCP/IP connection?
    Can i get help regarding this issue?

    ATE0
    AT+CMEE=1
    AT+CGDCONT=1,"IP","airtelgprs.com
    AT+CGACT=1,1
