Milesight D2D Settings
Milesight D2D protocol is developed by Milesight and used for connection among Milesight devices without gateway. When D2D setting is enabled, WS51x can work as the Milesight D2D agent device to receive commands from Milesight D2D controller devices or work as Milesight D2D controller device to send commands to trigger D2D agent devices.
- Ensure the RX2 datarate and RX2 frequency in LoRaWAN settings are the same as the D2D controller device.
- Enable D2D Agent Settings, and define a unique D2D key to be the same as the setting in D2D controller device. (Default D2D Key: 5572404C696E6B4C6F52613230313823)
- Define a 2-byte hexadecimal control command (0x0000 to 0xffff) and command action. For example, you can configure a control command 1510 to turn on, turn off or reverse the button as below. WS51x supports 16 control commands at most.
