Sometimes, there might be more than one video for a single project. You can find these videos in this section. Explore more through this this dedicated video. Lasy week I was working on a project that required two-way communication between two Raspberry Pi Picos, using MicroPython. This week, I’ll show you how to set up two-way Bluetooth communication between a Raspberry Pi and a Pico using MicroPython (or any bluetooth device capable of running MicroPython). What You’ll Need Raspberry Pi Pico W / WH Raspberry Pi (I’m using a Raspberry Pi 5) Setting Up the Raspberry Pi First, we need to set up the Raspberry Pi. I’m using a Raspberry Pi 5, but you can use any Raspberry Pi that has Bluetooth capabilities. It’s best to create virtual environments when working with Python, so we’ll create a virtual environment for this project, and then activate it. python3 -m venv venv source venv/bin/activate Installing the bleak Library We need to install the bleak library on the Raspberry Pi. This library allows us to communicate with Bluetooth devices. pip install bleak Setting Up the Raspberry Pi Pico Next, we need to set up the Raspberry Pi Pico. Flash the latest version of MicroPython onto the Pico - for a reminder of how to do this click here: How to install MicroPython. Setting Up the Code Now that we have the Raspberry Pi and the Raspberry Pi Pico set up, we can start writing the code. The repository has 4 lessons, each building on the previous one. The lessons are: Lesson 1 - Basic Bluetooth Communication Lesson 2 - Better Two-Way Communication Lesson 3 - Temperature Sensor example In each lesson folder there is a pi_demo.py file and a pico_a.py file. These files contain the code that runs on the Raspberry Pi and the Raspberry Pi Pico, respectively. You can save the pico_a.py file to the Pico by dragging and dropping it onto the Pico drive, and if you rename that file to main.py, it will run automatically when the Pico is powered on. You can find the code for this project on GitHub. The lessons are used in the YouTube video thats linked at the top of this article.
