How to create a Raspberry Pi Bluetooth Camera Driver

The new Raspberry Pi Camera Module 3 offers exceptional image quality and a choice between standard (75°) and wide (120°) lenses. Best of all, we now have autofocus. Take pictures with Picamera2 Easy, but sometimes we just want to press a button, take a picture, and be in the shot!

In this project, we will be using Blue Dot, a Python module, and an Android app to create a Bluetooth-controlled camera trigger. Thanks to the easy-to-use Blue Dot library and Picamera2’s verbose structure, we’ll capture 1080p images with just a small amount of code.

For this project you will need

  • Raspberry Pi 3 or 4
  • Raspberry Pi camera
  • Android device

Install the Raspberry Pi Camera Module

1. Open the camera port Gently lift the plastic lock up.

2. Insert the ribbon connector with the blue tab facing the USB/Ethernet ports. Raspberry Pi Zero users will need to use an adapter and connect the camera to the port on the right side of the board.
