I have a lora watch now, and every time I turn it on, it sends a data ‘/wD/’ synchronization time command, which translates to hex, which is FF00FF, My question now is how to receive this instruction in chirptack and then issue the synchronization time instruction through encodeDownlink. I also want to know how encodeDownlink works and what parameter is represented by input.data . When does encodeDownlink run
注明：设备开机后，会自动发送请求时间同步指令。需要收到同步指令后回复同步时间数据帧进行设备时间同步
（Note：After the device is turned on, it will automatically send a request time synchronization command. Need to reply to the synchronization time data frame after receiving the synchronization instruction to synchronize the device time)
