Bluetooth Interfacing

[DJ.]

Hello all,

I am trying to communicate with 2 bluetooth module where one is connected with ARM and another connected with PIC.
I am able to enter in the command with LLL.
All the commands I am able to execute properly, but on making the connection using AT+CON, it is replying CON:0 which means connection is not establish.
Is there any mistake i am making in it....Can anybody help with me the steps which I should follow...

Hello Guys,

Sorry for the late reply...
I have used 2 bluetooth module at 2 different end with SPP profile.
Finally the things is working fine...

Step 1. Put the LLL command on the power-On of the bluetooth module with 60 Sec.
Step 2. AT+Mode=2 (Auto connect mode)(You can set the Master and slave mode as your req.)
Step 3. AT+INQ
you will get reply of the module available with address and name.
Step 4. AT+CON="Bluetooth Address","Profile"(I used the SPP profile)
If the reply is CON:1 with that bluetooth address then your coonection has been established.

May be somebody will find it useful..
