Semtech #LoRaWAN Stack is structured according to IEEE 802.15.4 ... Yep LoRaWAN shares the same legacy as Thread, Zigbee and 6LoWPAN! We shall port this #IoT Legacy to #BL602

What's MCPS in the #BL602 #LoRaWAN Driver? ... That's the "MAC Common Part Sublayer", which is defined in the Semtech LoRaWAN Stack

The Node Layer (centre) in our #BL602 #LoRaWAN Driver handles the networking operations for our BL602 LoRaWAN Node ... It's called by the Application Layer (left)

#Mynewt OS has a #LoRaWAN Command-Line App that calls the Application Layer of the LoRaWAN Driver ... We shall port this app to #BL602 too
https://mynewt.apache.org/latest/tutorials/lora/lorawanapp.html

The Application Layer (left) of our #BL602 #LoRaWAN Driver exposes LoRaWAN Functions to Application Firmware ... Join Network, Open/Close Port, Transmit/Receive Packets
