hi, i try to interfacing pic microcontroller with bluetooth module(HC-05). but i don't have any idea in this technique. i search this content in website but no proper references is obtain. so please any one has see this post please reply.
That BT module uses a serial interface with the Pics so almost ay chip with a USART will do.
However the HC-05 runs at 3v3 so if possible, choose a Pic that operates at that voltage, though that will depend of what other devices the Pic is driving, eg display, 5v or 3v3 ?
