When M0 = 0，M1 = 0，the module works on Mode 0
The module receives the users' data of serial port, and transmit 58 bytes wireless data packet. When the
input data packet reaches 58 bytes, the module will start the wireless transmission, thus users can continue
to input the transmitting data; When the input data p acket is less than 58 bytes, the module will wait 3 by tes
time, if there's no more data packet input, it means the data input finished, so the module will send all data
packet out via wireless; After the module receives the first data packet, the AUX outputs low level; When
module put all data into RF chip and start the transmission, the AUX outputs high level; At this time, it
means the last data packet starts wireless transmission, users can continue to input 512 bytes data at most;
The data packet sent in M ode 0 can be only received by the module with M ode 0 and M ode 1.
The module always open the wireless receiving function on, then it can receive the data packet sent by
M ode 0 and M ode 1.
After receiving the data packet, the AUX of module outputs low level and after delaying 5ms, the wireless
data will be transmitted via TXD pins of serial port. After all wireless data is transmitted via serial port, the
AUX outputs high level.
When M0 = 1，M1 = 0，the module works on Mode 1
The condition of module starting data packet transmission and the AUX function equal to M ode 0. The
only difference is that module will add wake-up code automatically before each data packet. The length of
wake-up code depends on the wake-up time set by users, the purpose of wake-up code is to wake up the
module with M ode 2; So, the transmitting data in M ode 1 can be received by the module with M ode 0, 1,
2.
It equals to M ode 0.
When M0 = 0，M1 = 1，the module works on Mode 2
The module is on sleep mode, serial port is close, so it cannot receive the serial port data of external M CU.
Thus, this module does not feature wireless transmitting function.
In mode 2, the transmitter must be work in M ode 1; M onitoring the wake-up code at regular time, once a
valid wake-up code is received, the module continue to receive and wait for the entire valid data packet t o
be received; Then AUX outputs low level, after delaying 5ms, the serial port is open and the received
wireless data will be transmitted via TXD, after that, AUX outputs high level; Wireless module continue
to enter "Sleep-M onitor"working mode(polling); Set different wake-up time, the module has different
receiving response time (max 2s) and different average power consumption(min 30uA); Users need to
strike a balance between communication latency and average power consumption.
When M0 = 1，M1 = 1，the module works on Mode 3
Transmitting the wireless data is unavailable.
Receiving the wireless data is unavailable.
