IBM LMIC Port for sodaq One?

Is there a port of IBM’s LMIC LoRaWAN in C stack for the sodaq one, or ar least for the RN2483 Transceiver?

The LoRaWAN stack comes as part of the firmware loaded onto the RN2483 & RN2903. The firmware is developed by Microchip, and as far as I am aware is not modifiable. However, it may be updateable using supplied binaries from Microchip.
