4.2 Reading Operating Parameters
Instruction format Description
C1+C1+C1
In sleep mode（M0=1，M1=1），
User gives the module instruction (HEX format): C1 C1 C1,
Module returns the present configuration parameters.
For example, C0 00 00 1A 17 44.
4.3 Reading Version Number
Instruction format Description
C3+C3+C3
In sleep mode（M0=1，M1=1）,
User gives the module instruction (HEX format): C3 C3 C3,
Module returns its present version number, for example C3 44 xx yy.
44 here means the module model (E44 series); xx is the version number and yy refers to the other module
features.
4.4 Reset Instruction
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.
4.5 Parameter Setting Instruction
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

（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 8E1
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.
