plz clearly mention the format you are using. it is better to use windmill s/w instead of hyper terminal to send the cmds.
0x0d
0x0a
a
t
+
cmd
0x0d
0x0a

like this send the cmds after LLL.
here 0x0d means <cr>
0x0a means <lf>.
once try this.
all the best.

Hello World,
It would be wonderful if anyone can help me in this. Im using AUBTM-20 which is connected to my computer via serial port, Everything works fine-sending and receiving data from my mobile.. Can anyone tell me how to exit and SPP mode from my computer..I mean what command should we use to end the SPP mode..and another big problem with AUBTM-20 is when a device gets disconnected it is impossible to get it connected again unless and until we reboot the whole bluetooth device..can anyone give me an easier way to solve this problem..

Thanks and Regards
