199 199  The LT-22222-L supports both OTAA (Over-the-Air Activation) and ABP (Activation By Personalization) methods to activate with a LoRaWAN Network Server. However, OTAA is the most secure method for activating a device with a LoRaWAN Network Server. OTAA regenerates session keys upon initial registration and regenerates new session keys after any subsequent reboots. By default, the LT-22222-L is configured to operate in LoRaWAN Class C mode.
