the data through wireless transmission & go dormancy 1ms later automatically, which reduces MCU working time &
save power.

Likewise, this feature can be used in any mode-switch. The module will start to work in new mode within 1ms after
completing present mode task, which enables the user to omit the procedure of AUX inquiry and switch mode swiftly.
For example, when switching from transmitting mode to receiving mode, the user MCU can go dormancy before
mode-switch, using external interrupt function to get AUX change so that the mode-switch can be realized.

This operation is very flexible and efficient. It is totally designed on the basis of the user MCU’s convenience, at the
same time the work load and power consumption of the whole system has been reduced and the efficiency of whole
system is largely improved.

C0 + working parameters
C0 + 5 bytes working parameters are sent in hexadecimal format. 6 bytes in total and must
be send in succession.

Ordinary
transmitting
operation
User can transmit the data when the modules are synced (PINLOCK = 1(high level)).
Benefit of the TDD feature, user can perform transmitting while receiving. The maximum
size of the data which can be transmit at one time is 2048 Bytes. After the AUX has
turned to 0(low-level), User can perform another 2048 Bytes transmitting operation. The
TDD feature is available whatever the air data rate or the baud rate is.
Continuous
transmitting
operation
The module can transmit data continuously with some particular combination of air data
rate and baud rate, which has been show below.
Air Data Rate = 16Kbps, Baud rate <= 2400bps;
Air Data Rate = 32Kbps, Baud rate <= 4800bps;
Air Data Rate = 64Kbps, Baud rate <= 9600bps;
Air Data Rate = 128Kbps, Baud rate <= 19200bps;
Notes: Although higher air data rate brings lower transmission delay and it allows user
transmits the data continuously at higher baud rate, the communication range will be
shorter.
Type
When M0 = 1, module works in mode 1.
Transmitting
N/A. User can configure the module at baud rate = 9600bps, parity = 8N1.
Receiving
N/A. User can configure the module at baud rate = 9600bps, parity = 8N1.
