2. Define a unique LoRa D2D key that is the same as LoRa D2D agent devices, then select the frequency and spreading factor. (Default LoRa D2D Key: 5572404C696E6B4C6F5 2613230313823)
3. Enable one of the WS101 button modes and configure a 2-byte hexadecimal command (This command is pre-defined in LoRa D2D agent device). When you press as this button mode, WS101 will send the control command to corresponding LoRa D2D agent devices.
   Note:
   When this feature is enabled, the device will not send uplinks to the LoRaWAN® network server.
