7.4 Reset command
Instruction format
Description
C4+C4+C4
In sleep mode
（
M0=1
，
M1=1
）
,
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.

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
