i have checked out with one of the app .
http://www.instructables.com/id/How-to-Receive-Arduino-Sensor-Data-on-Your-Android/i took a refrrence from this siteto see whether im able to get text on app or not.
and yes it perfect worked.
Okay, this is good news. So on the arduino / bluetooth module side, everything is okay.
but when im trying the same thig with the TTS app,
it doesnt work
It could be a problem with the settings of the TTS app. What kind of settings does it have?
baud rate?
serial port?
android TTS engine?
You could try to send serial messages to your android phone from your PC, and see if the TTS app responds.
From this point on, I don‘t think you will find much help in the arduino forum anymore, since you have now narrowed down the problem to the interaction between the android bluetooth serial port and the TTS app.
Try another serial -> TTS app.
Check out the source code of the TTS app. Follow the link in the google play store. It takes you to GitHub.
Even if you can‘t get it to work - do a proper documentation about all the research and troubleshooting you have done to isolate the problem. This will impress your teacher more than some working setup, which you don‘t even understand why it works. Anybody can download an app. But not anybody can find and fix problems.
Good luck.
