![]() ![]() For your application it will work best to only receive small, single packet messages at a time. Unlike the Arduino versions of the RFM9x library there is no interrupt support which means when a packet is received it must be immediately processed by the Python code or it could be lost. Receiving packets is a 'best effort' in pure Python code.The size of the radio's internal buffer dictates this limit so if you want to send longer messages you'll need to break them into a series of smaller send calls in your application code. ![]() ![]() You can only send and receive packets up to 252 bytes in length at a time.Keep these in mind as you think about projects using the RFM9x and CircuitPython: One thing to be aware of before you use the RFM9x series of radios with CircuitPython are some of the limitations and design considerations for its module. ![]()
