Transmitting
UART is closed, the module cannot receive any serial port data from outside MCU.
Hence the function of wireless transmission is not available for the module working in this mode.
Receiving
In mode 2, it is required the data transmitter works in mode 1.
The wireless module monitors the preamble code at regular time.
Once it gets the preamble code, it will remain as receiving status and waiting for the completion of receiving the
entire valid data package.
Then the AUX outputs low level, Sms later the serial port is open to transmit received wireless data through
TXD. Finally, AUX outputs high level after process completed.
The wireless module stays in "power-saving — monitoring" working status (polling).
By setting different wake-up time, the module will have different receiving response delay (2s in maximum) and
average power consumption (30uA in minimum).
The user needs to achieve a balance between communication delay time & average power consumption.

Parameter This mode can be used for parameter setting. It uses serial port 9600 & 8N1 to set module working parameters
setting through specific instruction format. (pls refer to parameters setting for details)
When the mode changes from stand-by mode to others, the module will reset its parameters, during which the
Notes AUX keeps low level and then outputs high level after reset completed. It is recommended to check the AUX
rising edge for user.
7 Command format
In sleep mode ( Mode 3 : M1=1, M0=1 ) , it supports below instructions on list.
(Only support 9600 and 8N1 format when setting)
Instruction .
No. Nlustration
format
1 CO+working C0 + 5 bytes working parameters are sent in hexadecimal format. 6 bytes in total and
parameters must be sent in succession, ( Save the parameters when power-down ).
2 CI+C1+C1 ( Save the parameters when power-down )
3 C2+working Three C1 are sent in hexadecimal format. The module returns the saved parameters and
parameters must be sent in succession.
