I'm trying to implement communication between LoRaWAN and module using RFM95W with STM32L476. The problem I'm facing is that there is no library for dealing with OTAA and I wasn't able to find any relevant source how it looks like or how it works. Now I'm just able to send raw packets. It would be better if I coded the communication myself but I'm ok with working library, thanks
This protocol uses DevEUI AppEUI and AppKey
There are many libraries for stm32 for LoRa. For myself I go with the official LoRaMac-node from semtech. If your starting the journey into C and STM32, you can just start with the mbed-os.
