The LoRaWAN stack adapted for Arduino and a cortex-M0+ in a Freescale KL46Z board.
The 3 types of nodes are working (A, B and C) in both APB and OTT authentication.
The library used for Aduino is the LMIC library with a few adjustments.
For de Freescale we use the LoraMac-node implementation made by Semtech and adapted specially for this microcontroller.
