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

[EmmFalc]

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)

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.

Thank you, I'll take a look then.
