7.5 Parameter Setting Instruction
No. Item Description Notes
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

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.

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.
