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

https://en.wikipedia.org/wiki/IEEE_802.15.4

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

https://stackforce.github.io/LoRaMac-doc/LoRaMac-doc-v4.4.7/index.html

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)

For #Arduino Fans: RAKwireless has a #WisBlock #LoRaWAN Tutorial ... We shall try this later

https://github.com/RAKWireless/WisBlock/tree/master/examples/communications/LoRa/LoRaWAN

#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

Our #BL602 #LoRaWAN Driver has many Layers (like Shrek) ... Let's peel the Shrek ... (erm) Layers 🧅

Now we port the #LoRaWAN Driver ... From Apache #Mynewt OS to #BL602

#BL602 #LoRaWAN Driver ... Neater now

https://github.com/lupyuen/bl_iot_sdk/tree/lorawan/components/3rdparty/lorawan

#BL602 #LoRaWAN Driver ... Gets messy 🤔

https://github.com/lupyuen/bl_iot_sdk/tree/lorawan/components/3rdparty/lorawan

"Build Rot" ... Automated Builds need to be fixed every month or so ... Even though nothing has changed 🤔
