Introduction¶

CircuitPython RFM69 packet radio module. This supports basic RadioHead-compatible sending and receiving of packets with RFM69 series radios (433/915Mhz).

Note

This does NOT support advanced RadioHead features like guaranteed delivery–only ‘raw’ packets are currently supported.

Warning

This is NOT for LoRa radios!

Note

This is a ‘best effort’ at receiving data using pure Python code–there is not interrupt support so you might lose packets if they’re sent too quickly for the board to process them. You will have the most luck using this in simple low bandwidth scenarios like sending and receiving a 60 byte packet at a time–don’t try to receive many kilobytes of data at a time!

Dependencies¶

This driver depends on:

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Usage Example¶

See examples/simpletest.py for a simple demo of the usage.

Building locally¶

To build this library locally you’ll need to install the circuitpython-build-tools package.

python3 -m venv .env
source .env/bin/activate
pip install circuitpython-build-tools

Once installed, make sure you are in the virtual environment:

source .env/bin/activate

Then run the build:

circuitpython-build-bundles --filename_prefix adafruit-circuitpython-rfm69 --library_location .
