yes Bluetooth is working. I hae checked with another app, whre you send data from Arduino and displays data in the app. that worked.any TTS code is neccesary in the arduiono code?
In view of the fact that everything else is working, then quite possibly. It seems clear that there is nothing wrong with bluetooth, the connection procedures, or the wiring, and the only problem is that the Android app is not getting the data it needs to get because, as I said in reply #24, you're not sending it properly. This may be just a matter of formatting.
