network
In this wiring, the user MCU can realize wireless serial port communication between multiple
MCU, and can also control the output IO level of all nodes, and read the input IO level status
(input1 to input5).
Example 1: Serial port of local 0005 device sends 112233445566 hex data to the serial port of
target 0008 device
Instruction: 41 54 2b 4d 45 53 48 00 00 08 31 32 33 0d 0a
Example 2: Serial port of local 0005 device serial port sends 112233445566 hex data to all device
serial ports in the network
Instruction: 41 54 2b 4d 45 53 48 00 ff ff 31 32 33 0d 0a
Example 3: Serial port of local 0005 device reads 5 OUTPUT pin levels of target 0008 device
