UART opens.
Wireless
closes
and
continuous transparent 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.
