Hi,
Thanks Marcel for your reply! And I have solved the
first problem,I created a rfcomm connection,and sent
data sucessfully! Thanks again!

However,I am still puzzled with then second
problem.What I did is as follows:
on platform A: 
$ rfcomm listen 0 1
Waiting for connection on channel 1

on platform B: 
$ hsmicro 4A:49:4E:00:15:2F 1
-t: No such file or directory
Voice setting: 0x0060
RFCOMM channel connected
SCO audio channel connected (handle 44, mtu 64)

O
                                                      
                                                      
K
                                                      
                                                      
 
O
K
                                                      
                                                      
 
                                                      
                                                      
 ....

Then ,I inserted a microphone into the MC145483 Codec
on platform B and spoken,but on platform A there was
no response from the Code's speaker! 
Please correct me if i"m wrong. Do I need to add some
services such as HS,HF,A2SRC and A2SNK?
Or maybe there is something wrong on the connection
between Bluetooth module's PCM interface and the
Motoral MC145483 Codec?

I am really confused now!

you can't listen only for a RFCOMM channel. You must also listen for a
SCO connection. Why don't you test with scotest as I told you last time.

This depends on the tools. Most Linux tools will also work without any
service records if you specify the right command line parameters.

This can be, but how should I know?
