my bluetooth connection is working.
Is this true?
Have you tried sending your data to a standard Bluetooth Terminal? If that works, it is not a bluetooth problem, and may not be an Arduino problem.
Assuming the output was useable by TTS, there was nothing fundamentally wrong with your code as posted, it was just your error in application. You had two options.
- change bluetooth to pins 0,1, which I assume you ignored. It was not even necessary to edit the code.
- rewrite the code to use software serial in the proper manner
Doing both is not an option.
