Howdy,
So I'm working on a project that uses an HC_06 bluetooth module and an app to control my arduino. The code works and the module works fine. My app sends numbers 1-9 and the micro receives this info and does other crap with it. Recently I migrated the arduino micro to a circuit board following the guidelines laid out by http://arduino.cc/en/Main/Standalone#.UxpQlvldUnM (with the exception of using a ceramic resonator) and the communication got screwed up. Now the micro doesn't receive the right information. It usually receives garbage data.
My questions are as follows:
Should i be using a crystal instead of the resonator?
Is there supposed to be some sort of filter between the bluetooth module tx pin and the micro rx pin?
Everything works fine if i use my arduino and the only thing that doesn't work is receiving the the transmitted information.
Thanks
