1 Continuous mode
0
0
1
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.
2 Sub-package mode
0
1
0
UART opens. Wireless closes and sub-
package
transparent transmission
is
available.
Air data rate and baud rate can be
adjusted separately. It is applicable
for data packet transmission.
3 Configuration mode
0
1
1
UART opens. Wireless closes and parameter
can be configured.
Baud rate is fixed as 9600 8N1.
4 WOR mode
1
0
0
UART opens. Wireless
closes
and
subpackage transparent transmission is
available.
Receiving is not available under
this mode. Preamble code will be
added
proactively
before
transmission to wake up the
receiver under mode 6.

6 Power saving mode
1
1
0
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.
7 Sleep mode

1
UART closes, wireless transmitting is
available and sleep mode is on.
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 a fter 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.
If the module switches from other modes to stand-by mode, it will work in stand-by mode only after all the remained
data process completed. The feature can be used to save power consumption. For example, when the transmitter
works in mode 0, after the external MCU transmits data “12345”, it can switch to sleep mode immediately without
