UART Interface Protocol
UART Interface：
Start bit：1
Data bit：8
Parity bit：None
Stop bit：1

Data Format：
Module ground
(2 Byte)
length(1 Byte)
command(1Byte) Data(n Byte)
verify(1 Byte)
Module address: fixed to 0x00 for a module used alone;
For the network version module, it is 0x01~0XFE; 0xFF is broadcast (no answer).
Note: The module address is exactly the same 2 bytes.
Length: length (1Byte) + command (1Byte) + data (nByte)
Command: valid command (Reference command table)
Data: valid data
Check: length (1Byte) + command (1Byte) + data (nByte) XOR
Return data format：
Command
length(1Byte)
Success/failure
value(1Byte)
Data(n Byte)
verify(1 Byte)
header(1Byte)
Command header: 0xFE
Length: Length (1Byte) + Command (1Byte) + Data (n Byte)
Success/Failure value: (Reference command table)
Data: If there is data returned, it is valid data
Verify: Length (1Byte) + Command (1Byte) + Data (n Byte) XOR
