module will process this data, including sending and receiving, before entering sleep mode. This feature can be used for
fast sleep, thus saving power consumption; For example: the transmitter module works in mode 0
, the user
initiates the
serial port
data "
12345"
, and
then does not have to wait for
the
AUX pin to be idle (high level), you can directly switch to
sleep mode, and the user's main MCU immediately sleeps, the module will automatically send all the user data through
the wireless Automatically enter sleep within 1ms; This saves the working time of the MCU and reduces power
consumption.
Similarly, any mode switch can take advantage of this feature, after the module processes the current
mode event,
within
1ms, it will automatically enter the new mode; Thus, the user's work of querying AUX
is omitted
, and the purpose
of fast switching can be achieved; For example, switching from transmit mode to receive mode; The user MCU can also
go to sleep early before the mode switch and use the external interrupt function to capture the AUX change for mode
switching.
This operation is very flexible and efficient, designed exactly for the user's MCU to operate, and can minimize the
workload of the entire system, improve system efficiency, and reduce power consumption.

Baud rate and
airspeed
Based on the user's baud rate setting, the module automatically calculates the minimum airspeed required to meet
continuous output requirements. Since modules with different airspeeds cannot communicate, the serial port
parameter settings of both sides of the sending and receiving must be consistent.
merit
The serial data output of the wireless receiver is continuous, which meets the continuous transmission requirements of
