The LoRaWAN stack used in LA66 is used in more than 1 million LoRaWAN End Devices deployed world widely.  This mature LoRaWAN stack greatly reduces the risk to make stable LoRaWAN Sensors to support different LoRaWAN servers and different countries' standards. External MCU can use AT command to call LA66 and start to transmit data via the LoRaWAN protocol.
