5. Functional Details
5.1 Module Reset
When the module is powered, AUX outputs low level immediately, conducts hardware self-check and sets the operating
mode on the basis of the user parameters. During the process, the AUX keeps low level. After the process completed, the
AUX outputs high level and starts to work as per the operating mode combined by M1 and M0. Therefore, the user needs
to wait the AUX rising edge as the starting point of module’s normal work.
5.2 AUX description
AUX Pin can be used as indication for wireless send & receive buffer and self-check.
It can indicate whether there are data that are yet to send via wireless way, or whether all wireless data has been sent
through UART, or whether the module is still in the process of self-check initialization.
5.2.1. Indication of wireless reception
After the module receives valid wireless data, it will immediately pull down AUX and start the serial port output data.
After the data output is completed, AUX is pulled. high.
5.2.2. Indication of wireless transmitting
Buffer (empty): the internal 80 bytes data in the buffer are written to the RFIC (Auto subpackage). When AUX=1, the
user can input data less than 80 bytes continuously without overflow.
Buffer (not empty): when AUX=0, the internal 80 bytes data in the buffer have not been written to the RFIC completely.
If the user starts to transmit data at this circumstance, it may cause overtime when the module is waiting for the user data,
or transmitting wireless subpackage.
Notes: When AUX = 1, it does not mean that all the UART data of the module have been transmitted already, perhaps the
last packet of data is still in transmission.

5.2.3.Configuration procedure of module
Only happened when power-on resetting or exiting sleep mode.
5.2.4. Notes for AUX
For function 1 & function 2 mentioned above, the priority should be given to the one with low level output, which
means if it meets each of any low level output condition, AUX outputs low level, if none of the low level condition
is met, AUX outputs high level.
When AUX outputs low level, it means the module is busy & cannot conduct operating mode checking. Within 1ms
since AUX outputs high level, the mode switch will be completed.
When the user switches to other operating modes from mode 3 (sleep mode) or it’s still in reset process, the module
will reset user parameters, during which AUX outputs low level.

6.1 Mode switching
The user can decide the operating mode by the combination of M1 and M0. The two GPIO of MCU can be used to
switch mode. After modifying M1 or M0, it will start to work in new mode 1 ms 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 0, 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 the output status of AUX pin and wait 2ms after AUX outputs high level
before switching the mode.
When the module is switched from other mode to sleep mode, if the data has not been processed yet, the module
will process the data (including the receive and send) before entering the sleep mode. This feature can be used for
fast dormancy to save power. For example, the transmitting module works in mode 0, the user initiates the serial
port data “12345”, and then does not have to wait for the AUX pin to be idle (high level), It can be switched to the
sleep mode,and immediately sleeps the users’ main MCU. The module will automatically transmit the user data
through the wireless, and automatically enters sleep mode within 1ms; thus saving the working time of the MCU
and reducing power consumption.
Similarly, any mode switch can use this feature. After the module processes the current mode event, it will
automatically enter the new mode within 1ms. Thereby eliminating the user's work of querying AUX, and achieving
the purpose of fast switching. For example, switching from the transmit mode to the receive mode; the user MCU
can also enter sleep before the mode switch, and use the external interrupt function to acquire the AUX change,
thereby performing mode switching.
This operation is very flexible and efficient, and is designed according to the user's MCU's operation convenience,
and can reduce the workload of the entire system as much as possible, improve system efficiency, and reduce power
consumption.
6.2 Transmission Mode (Mode 0)
When M1 = 0 & M0 = 0, module works in mode 0
Transmitting
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.
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.
Receiving
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 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.

8. Hardware Design
It is recommended to use DC stabilized power supply to supply power to the module. The power supply ripple
coefficient is as small as possible, and the module needs to be reliably grounded.
Please pay attention to the correct connection of the positive and negative poles of the power supply. If the reverse
connection is connected, the module may be permanently damaged.
Please check the power supply to ensure that between the recommended supply voltage, if exceeding the maximum,
the module will be permanently damaged.
Please check the stability of the power supply, the voltage can not be significantly frequent.
When designing the power supply circuit for the module, it is often recommended to reserve more than 30% of the
margin, and the whole machine is beneficial for long-term stable operation.
The module should be as far away as possible from the power supply, transformers, high-frequency wiring and other
parts with large electromagnetic interference.
High-frequency digital traces, high-frequency analog traces, and power traces must be avoided under the module. If
it is necessary to pass through the module, assume that the module is soldered to the Top Layer, and the copper is
spread on the Top Layer of the module contact part(All copper-covered and well grounded), and must be close to
the digital part of the module and routed in the Bottom Layer.
Assuming the module is soldered or placed in the Top Layer, it is also wrong to randomly route the Bottom Layer or
other layers, which will affect the module's spurs and receiving sensitivity to varying degrees.
Assuming that there are devices with large electromagnetic interference around the module, the performance of the
module will also be greatly affected. According to the intensity of the interference, it is suggested to stay away from
the module appropriately. If circumstances permit, appropriate isolation and shielding can be done.
Assume that there are traces with large electromagnetic interference around the module (high-frequency digital,
high-frequency analog, power trace), which will greatly affect the performance of the module. It is recommended to
stay away from the module according to the strength of the interference. If necessary, appropriate isolation and
shielding can be done;

If the communication line uses a 5V level, a 1k-5.1k resistor must be connected in series (not recommended, there is
still a risk of damage).
Try to stay away from some physical layers and also have a 2.4GHz TTL protocol, for example: USB3.0.
The antenna mounting structure has a great influence on the performance of the module. It is necessary to ensure
that the antenna is exposed, preferably vertically upward. When the module is mounted inside the case, use a good
antenna extension cable to extend the antenna to the outside of the case.
The antenna must not be installed inside the metal case, which will greatly reduce the transmission distance.
9. FAQ
9.1 Communication range is too short
The communication distance will be affected when obstacle exists.
Data lose rate will be affected by temperature, humidity and co-channel interference.
The ground will absorb and reflect wireless radio wave, so the performance will be poor when testing near ground.
Sea water has great ability in absorbing wireless radio wave, so performance will be poor when testing near the sea.
The signal will be affected when the antenna is near metal object or put in a metal case.
Power register was set incorrectly, air data rate is set as too high (the higher the air data rate, the shorter the
distance).
When the power supply at room temperature is lower than the recommended low voltage, the lower the voltage is,
the lower the transmitting power is.
Due to antenna quality or poor matching between antenna and module.
9.2 Module is easy to damage
Please check the power supply and ensure it is within the recommended range. Voltage higher than the peak will
lead to a permanent damage to the module.
Please check the stability of power supply and ensure the voltage not to fluctuate too much.
Please make sure anti-static measures are taken when installing and using, high frequency devices have electrostatic
susceptibility.
Please ensure the humidity is within limited range for some parts are sensitive to humidity.
Please avoid using modules under too high or too low temperature.
9.3 High bit error rate
There are co-channel signal interference nearby, keep away from interference sources or modify frequency, channel
to avoid interference.
Unsatisfactory power supply may also cause garbled characters, and ensure the reliability of the power supply.
If the extension cable or feeder is of poor quality or too long, the bit error rate will be high.
