Why #LoRaWAN is so complex ... And why we should stick to the official Semtech Drivers for LoRa and LoRaWAN

https://lupyuen.github.io/articles/sx1262?3#lorawan-support

We port the #LoRa SX1262 Driver to #NuttX OS ... In small steps

https://lupyuen.github.io/articles/sx1262?2#small-steps

Porting the #LoRa SX1262 Driver from Linux to Apache #NuttX OS ... All shall be explained in this article

https://lupyuen.github.io/articles/sx1262?1

Our plain and simple #NuttX #LoRa SX1262 Library is (nearly) done! Porting the library from Linux to NuttX wasn't so hard ... Moving on to LoRaWAN real soon!

Now our #NuttX SX1262 Library shall receive a #LoRa Message ... Transmitted by #RAKwireless WisBlock
