    How to enable the echo mode using AT commands on Nokia Bluetooth mobile phones

    Hello,
    I'm currently working on a project whose purpose is to allow the maximum of bluetooth mobile phoness users to control a software. To make it, I thought I could use AT commands, making the phones send the codes of the keys pressed thanks to the AT+CMER command. But testing different models of phones, I didn't manage to do it with with the Nokia ones by using AT+CMER. So, is it really impossible to do it this way ? Is there another AT command I could use to retrieve the keys pressed ?

    Hi,
    This is not the answer you want but at least the source is good

    6310 and +CMER

    If you want to Google further try "AT +CMER (nokia)"

    My 6230i over bluetooth and hyperteminal is

    at+cmer=?
    +CMER: (0-3),(0),(0),(0-2),(0)
    12.2 AT+CMER Mobile Equipment Event Reporting
    HFP, Section 4.24.2 /11/. The Set command enables or disables sending of unsolicited result codes from TA to TE in the case of key pressings, display changes, and indicator state changes. <mode> controls the processing of unsolicited result codes specified within this command. <bfr> controls the effect on buffered codes when <mode> 1, 2, or 3 is entered. The test command returns the modes supported by the TA as compound values.
    Command
    Response
    +CMER=[<mode>[,<keyp>[,<disp>[,<ind>[,<bfr>]]]]]
    +CMER?
    +CMER: <mode>,<keyp>,<disp>,<ind>,<bfr>
    +CMER=?
    +CMER: (list of supported <mode>s),(list of supported <keyp>s),(list of supported <disp>s),(list of supported <ind>s),(list of supported <bfr>s)
    Table 12.2: AT+CMER
    AT Command Set For Nokia GSM And WCDMA Products 90
    From the document


    AT Command Set For Nokia GSM

    Good luck

    Thank you for your quick response Jim.
    Too bad that the +CMER isn't supported. Then, I'll try it another way I think.

    Hi EmmFalc,
    Java programs will read the keypad, its documented in the games library API. Then you need to make a bluetooth connection to the game server and deliver the key presses to the server as integers.
    The Sun Wireless Toolkit gives some good examples of this.
