Ebyte E32-433T30D - Sleep Mode (Mode 3); T Command Format; Default Parameters

Bhe Chengdu Ebyte Electronic Technology Co,Ltd E32-433T30D user manual
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.
6.5 Sleep mode (mode 3)
‘When M1=1, M0=1, module works in mode 3
Transmitting N/A
Receiving N/A
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 AUX
Notes keeps low level and then outputs high level after reset completed. It 1s 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)
