Quick heads up for those in EU or regions where 433Mhz is legal (sometimes called 434Mhz). Since I never used straight 433Mhz with RFM69, other than in various tests and experiments, I was somewhat ignorant about this band.| LowPowerLab
The RFM69 library has been very robust and stable over the years. It is widely used in many hobby and home automation projects as well as research and commercial products. But that doesn’t mean we can’t find occasional things to fix and improve!| LowPowerLab
