Plain and Simple LoraWan (LowPower) Library for STM32
I have made some example project with a new library to keep code simple and to reduce power as much as possible. I am testing now with CR2032 and LR44 batteries. Sleep current is about 1.4uA without sensor and 2.4uA with BME280 sensor. Transmit power is reduced and also the (sleep) power during RX1/RX2 window.
Results of the batteries test will be published as soon as the batteries are depleted. Here is the article already:

Have fun and happy holidays!
