Robust Arduino Serial Protocol in Python

Robust Arduino Serial is a simple and robust serial communication protocol. It was designed to make two arduinos communicate, but can also be useful when you want a computer (e.g. a Raspberry Pi) to communicate with an Arduino.

It supports Python 3.8+.

This repository is part of the Robust Arduino Serial project, main repository: https://github.com/araffin/arduino-robust-serial

Please read the Medium Article to have an overview of this protocol.

Documentation: https://python-arduino-serial.readthedocs.io

Implementations are available in various programming languages:

• Arduino
• Python
• C++
• Rust

Installation

Using pip:

pip install robust_serial

From Source:

git clone https://github.com/araffin/python-arduino-serial.git
pip install -e .

Tests

Run the tests (require pytest):

make pytest

Examples

Read write in a file (WARNING: the file will be deleted when the script exits)

python -m examples.file_read_write -f test.txt

Serial communication with an Arduino: Arduino Source Code

python -m examples.arduino_serial

Example: Communication with Sockets

It can be useful when you want two programs to communicate over a network (e.g. using wifi) or even locally on the same computer (e.g. when you want a python2 script that communicates with a python3 script).

1. Start the server:

python -m examples.socket_example --server

2. Run the client:

python -m examples.socket_example --client

Bluetooth Example with Two Computers

Dependencies:

sudo apt-get install libbluetooth-dev bluez
pip install pybluez

You need to change the server mac address SERVER_ADDR, you can use hciconfig to know the mac address of your computer.

Server:

python -m examples.bluetooth_example --server

Client:

python -m examples.bluetooth_example --client
