Re: Use app to connect to pi via bluetooth.

Oops sorry it seems I have forgot to tell that I have a pi 2 and not pi3 and I had confused this post with another. I am very sorry and apologise for the inconvenience Douglas.

Re: Raspberry pi and HC-05

No actually I don't want that. What I want is to move my robot in different directions using my app. I have provided the Bluetooth client in my app which will only be able to work after pairing my Pi with my tablet. So what's the procedure for that?

In order to communicate with the app and the pi I am using a HC-05 and my RX and TX are in line with 3v3. Next what? Searching the net I found the tutorials are about serial comm...

Re: Raspberry PI GPIO Pins behaving strangely

No. I have connected raspi's 5v to the logic pin, and used a separate battery (9v) for powering the motors. It worked earlier before my OS on the CD card got corrupted as I said in my first post. By 3v3 pins you mean the Generic GPIO pins? And at first I connected a led to GPIO4 it automatically get...

The motors are connected via the l293d motor driver board.....it has got three input pins for each motor and logic power to raspberry pi's 5v and of course the ground....and also 9v to power the two motors.....
