Type
When M1 = 0 & M0 = 0, module works in mode 0
The module can receive the user data via serial port, and transmit wireless data package of 40 bytes.
When the data inputted by user is up to 40 bytes, the module will start wireless transmission. During
which the user can input data continuously for transmission.
When the required transmission bytes are less than 40 bytes, the module will wait 3-byte time and
treat it as data termination unless continuous data inputted by user. Then the module will transmit all
the data through wireless channel.
Transmitting
When the module receives the first data packet from user, the AUX outputs low level. After all the
data are transmitted into RF chip and transmission is started, AUX outputs high level.
At this time, it means that the last wireless data package transmission is started, users can continue
to enter data up to 80 bytes.
The data package transmitted from the module working in mode 0 can only be received by the
module working in mode 0.
The wireless receiving function of the module is on, the data packet transmitted from the module
working in mode 0 can be received.After receiving the data packet, the AUX outputs low level, the
Receiving
module starts to transmit wireless data through serial port TXD pin. After all the wireless data have
been transmitted via serial port, the AUX outputs high level.
6.3 RSSI Mode (Mode 1)
Type
When M1 = 0 & M0 = 1, module works in mode 1.
Transmitting
N/A, the received serial data will be discarded.
N/A, only scan the signal strength of the current channel, and output an intensity value (relative value)
through the serial port every 100ms：

Configuratio
Can be used for module parameter setting, using serial port 9600, setting module working parameters
n
through specific instruction format.
When entering the other mode from the setup mode, the module will reconfigure the parameters.
During the configuration process, AUX remains low;
Note
After the completion of the output high level, it is recommended that the user detect the AUX rising
edge.
