This device is just plain dumb. People who are looking for a serial cable replacement : DONT BUY THIS.
It comes with the HID option set as factory default and your bluetooth will recognize this always as a keyboard and would not install a Serial Port for this. So you wont have any COM port set up to talk to the module, which you need to do to change it from HID to SPP. I was lucky enough to have a RS232 - TTL converter in my lab which I connected from my PC directly to the module and set it to SPP. Another possible way to configure correctly would be to wire the TX of your microcontroller to the RX of this module and send the text below at 115200 baud rate
though I have not tested this!! I got this module as it somehow looked 20bucks cheaper than other alternatives but it cost me 1 week of my time.
Can anybody tell me how to get spp back on this thing on xp or windows 7. It connects to my pc as a keyboard and I cannot associate a COM port with it, so I cannot send any commands.
I am working with a PIC16f690, have +5V power supply for the module and my PC with inbuilt bluetooth running win 7
No public wish lists :(
