Hi, I have succesfull conect the bluesmirf to an PC bluetooth dongle and use the SSP profile of it to achieve communication with hyperterminal. But I need to send messages between a phone and a MCU using bluetooth whitout using a java applet. Isn’t complicated connect those two devices using SSP profile but then I don’t know what to do, I suspect that I have to implement the OBEX protocol in the MCU, but not too sure. Does anyone achieve that kind of communication ? I haven’t find a proper solution in the forum
