When the module is switched from other modes to sleep mode, if there is data that has not been processed;
The module can enter the sleep mode only after processing these data (including receiving and sending).
This feature can be used for fast sleep to save power consumption; for example: the transmitter module
works in mode 0, the user initiates serial port data "12345", and then does not need to wait for the
3
AUX pin to be idle (high level), and can directly switch to sleep mode, Put the user's main MCU to
sleep immediately, the module will automatically send all user data wirelessly, and automatically
enter sleep within 1ms;
Thus, the working time of the MCU is saved and the power consumption is reduced.
In the same way, this feature can be used for any mode switching. After the module processes the current
mode event, it will automatically enter the new mode within 1ms; thus saving the user's work of querying
AUX, and achieving the purpose of fast switching ;
4
For example, switching from the transmit mode to the receive mode; the user MCU can also go to sleep
in advance before the mode switch, and use the external interrupt function to obtain the AUX change,
so as to switch the mode.
This operation mode is very flexible and efficient, and is completely designed according to the user's
MCU operation convenience, and can reduce the workload of the entire system as much as possible, improve
5
system efficiency, and reduce power consumption.
6.2 Normal Mode (Mode 0)
Type
When M0 = 0, M1 = 0, the module works in mode 0
Transceiving
Users can input data through the serial port, and the module will start wireless transmission.
The wireless receiving function of the module is turned on, and the wireless data will be output through
Receiving
the serial port TXD pin after receiving the wireless data.
6.3 WOR Mode (Mode 1)
Type
When M0 = 1, M1 = 0, the module works in mode 1
When defined as a transmitter, a wake-up code for a certain period of time will be automatically added
Transceiving
before transmission
Receiving
Data can be received normally, and the receiving function is equivalent to mode 0
6.4 Configuration Mode (Mode 2)
Type
When M0 = 0，M1 = 1，the module works in mode 2
Transceiving
wireless transmission off
