Remark: 1, MCU can use general I/O port to implement SPI interface, If SPI is 5 V level, refer to TI AN021
file for processing. GDO0, GDO2 according to the application connection, you can select one of
them as the send/receive interrupt request signal to control the MCU receive/send, or not
linking-up, and through the SPI port to read the module status to receive/send.
2, If an external antenna is selected, it can be connected to the product housing with an
extended cable. If the PCB antenna is selected, the part of PCB antenna should be floating as far
as possible, or at least the part is not grounded. PCB antenna surrounding can not have
transformers, crystals and other large metal parts to avoid affecting the distance.
3, Production can not be reflow welding, only manual welding.

4. Hardware design
Recommend to use the DCDC that the power ripple coefficient is smaller to supply the power if you can,
ensure proper grounding.
Verify the power source voltage falls within the specified range and confirm correct connection of
positive and negative terminal, failure to do so may result in modules breakdown due to overvoltage or
incorrect connections.
The power supply stability should be checked and maintained consistently.
Avoid proximity to components with significant electromagnetic interface, such as the power supply,
transformer and high-frequency cable.
The cable carrying power supply or high-frequency signals should not be routed through the bottom
of the module. If there is no alternative, ensure that the module is soldered on the layer
named‘Toplayer’, with grounding perimeter areas and copper, before laying the cable on the other
layer named ‘Bottomlayer’. The cable going through below the module, even on a different layer, may
result in signal scatting and desensitization.
In case of unavoidable electromagnetic interface, ensure proper isolation and shielding by adding a
shielding case.

5. Transmission issue
The transmission distance will decrease in presence of obstacles or shelter.
Changes in temperature, humidity, or frequency interface can increase packet loss rate.
Radio waves are absorbed and reflected by the ground, therefore, module performance worsens
as proximity to the ground. Recommend to keep a minimum distance of 1.5m from the ground if
possible.
Metal absorb radio waves, so it is important to keep antennas away from metal objects and avoid
placing them inside metal boxes.
The higher RF baud rate, The closer the transmission distance.
The TX power decreases as the voltage drops below the rated level.
Ensure the antenna and modules match.
6. Modules damage inspection
Check the power supply, ensure the voltage remains within the recommended range with
minimum fluctuation. Modules may become damaged if the voltage exceeds its maximum limit.
Maintain ESD protection for RF components which are electrostatic sensitive. Additionally, ensure
the humidity levels remain at an appropriate level as some components are sensitive to high
humidity levels.
Unless otherwise specified, it is not advisable to use this product in excessively high or low
temperatures.
7. High bit error rate issue
Same frequency signal interface, remove interface or modifying the frequency (interval 500MHz at
least) /RF channels.
Power supply instability, check and replace a stable one.
