--
  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.

  The LT-22222-L comes with device registration information such as DevEUI, AppEUI, and AppKey that allows you to register it with a LoRaWAN network. These registration information can be found on a sticker that can be found inside the package. Please keep the **registration information** sticker in a safe place for future reference.
