UART opens. Wireless closes and
continuous

transmission is available.
Air data rate can be adjusted automatically
according to baud rate. The baud rate must
be same on both receiver and transmitter. It
is applicable for high speed continuous data
transmission.

Air data rate and baud rate can be adjusted
separately. It is applicable for data packet
transmission.

UART closes. Wireless works at
WOR power saving mode.
Multiple time grades can be
configured.
Transmission is not available under this
mode. It can be woken up by transmitter
under mode 4 to achieve low power
consumption receiving.

It can be woken up by any falling edge of
M2, M1, M0.
6.1 Mode Switch
The user can decide the operating mode by the combination of M0, M1 and M2. The two GPIOs of MCU can be
used to switch mode. After modifying M0, M1 or M2, it will start to work in new mode 1ms later if the module is
free. If there are any serial data that are yet to finish wireless transmitting, it will start to work in new mode after
the UART transmitting finished. After the module receives the wireless data & transmits the data through serial
port, it will start to work in new mode after the transmitting finished. Therefore, the mode-switch is only valid
when AUX outputs 1, otherwise it will delay.
For example, in mode 2 or mode 4, if the user inputs massive data consecutively and switches operating mode at
the same time, the mode-switch operation is invalid. New mode checking can only be started after all the user’s
data process completed. It is recommended to check AUX pin out status and wait 2ms after AUX outputs high level
before switching the mode.
