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

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.
