Hello Recently i have purchased LM730/LM740 Bluetooth module......

How can i interface this module with the RS232....?? I want to send the AT commands i have made the schematic also and i will use the same in my existing circuit ..

But when i send a AT command to the Module using MAX232 it wont work......

Can anybody tell me how to test the LM730/LM740 bluetooth module separetely..

The schematic is attached.

I want to replace BTM1004C2P with LM730
