User gives the module instruction (HEX format): C4 C4 C4, the module resets for one time. During
the reset process, the module will conduct self-check, AUX outputs low level. After reset completing,
the AUX outputs high level, then the module starts to work regularly which the working mode can be
switched or be given another instruction.
7.5 Parameter setting command
No. Item Description Remark
0 HEAD
Fix 0xC0 or 0xC2, it means this frame data is
control command

Must be 0xC0 or 0xC2
C0: Save the parameters when power-down
C2: Do not save the parameters when power-down
1 ADDH
High address byte of module
（ the default 00H ）
00H-FFH
2 ADDL
Low address byte of module
（ the default 00H ）
00H-FFH
3 SPED
7 6 UART parity bit

UART mode can be different between
communication parties
0 0 8N1 (default)
0 1 8O1
1 0 8 E1
1 1 8N1 (equal to 00)
5 4 3 TTL UART baud rate （ bps ）

UART baud rate can be different
between communication parties

The UART baud rate has nothing to do
with wireless transmission parameters &
won’t affect the wireless transmit /
receive features.

1 0 1 38400
1 1 0 57600
1 1 1 115200
2 1 0
Air data rate （ bps ）

The lower the air data rate, the longer
the transmitting distance, better
anti-interference performance and longer
transmitting time

The air data rate must keep the same for
both communication parties.
