I'm trying to setup a bluetooth connection between my Windows Phone and a netduino plus 2 using a RN-42 bluetooth chip (Sparkfun mate silver board).


I have been able to pair the devices as well as send data from the phone to the RN-42. But I'm unable to send data  back, from the RN-42 to the phone.


How do I diagnose what is wrong?

After lot's of time wasted, I noticed the problem. I had the wrong baudrate set, so the data sent as gibberish #doh

How do you determine what the right baud rate is? Is it 9600 or 115200. I am running into a similar problem, the number of bytes that I receive is correct however the byte values are either 0 or 32.
