C4+C4+C4 

In sleep mode (M0=1, M1=1), a command (HEX format) is issued to the module serial  port:: 
C4 C4 C4, the module will generate  a reset; during the reset process, the module performs self-
test, AUX output low level,  After the  completion    of  reset, the AUX outputs high  and  the 

module  starts to  work  normally. At  this  time,  Users  can  switch  modes  or  initiate  the  next 
instruction. 

7.5 Parameter setting instruction

C0

The set parameters will be saved after 

power down. 

C2

The set parameters will not be saved 

after power down.

 

ADDH 

High byte of module address (default 00H)

  SPED 

Serial  parity bit 

The serial port mode of the two 

communication  parties can be different 

8N1

default

 

8O1 

8 E1 

8N1

equals to 00

 

      TTL Serial  port rate

bps

 

The baud rate of both parties can be 

different.                                                                                                                                                   

The serial port baud rate has nothing to 

do with the wireless transmission 

parameters, and does not affect the 

wireless transmission and reception 

characteristics. 

Serial  port baud rate 1200 

Serial  port baud rate 2400 

Serial  port baud rate 4800 

Serial  port baud rate 9600

default

 

Serial  port baud rate 19200 

Serial  port baud rate 38400 

Serial  port baud rate 57600 

Serial  port baud rate 115200                     

      Wireless air data rate

bps

 

The lower the air speed, the longer  the 

distance, the stronger the anti-

interference  performance and the longer 

the transmission time. 

The wireless transmission rates of both 

communicating  parties must be the same. 

Air data rate 1.2k

Air data rate 2.4k 

Air data rate 4.8k 

Air data rate 9.6k 

Air data rate 19.2k

425M  + CHAN * 0.1M ), default 50H

433M

 

OPTION 

Fixed point send enable bit

similar to M ODBUS

 

When value is 1, the first 3 bytes of each 

user data frame are used as the high  and
