wayne roberts / Mbed 2 deprecated LoRaWAN-demo-76_iks01a1

Sending IKS01A1 temperature sensor to LoRaWAN port-5 uplink

Dependencies:   X_NUCLEO_IKS01A1 mbed LoRaWAN-lib SX1276Lib

Fork of LoRaWAN-demo-76 by Semtech

Use IKS01A1 sensor shield with SX1272 shield or SX1276 shield.

Sends temperature sensor to LoRaWAN uplink port 5.

Remove SB22 and SB23 from IKS01A1 before using

SB28 conflicts with DIO0 on radio. (TxDone RxDone)

SB22 conflicts with RxTx on radio. (antenna switch)
