Chapter6. FAQ
6.1 Communication range is too short

When there is a straight line communication obstacle, the communication distance will be attenuated accordingly;

Temperature, humidity, and co-frequency interference will increase the communication packet loss rate;

The ground absorbs and reflects radio waves, and the test results near the ground are poor;

Sea water has a strong ability to absorb radio waves, so the seaside test results are poor;

If there is a metal object near the antenna or placed in a metal shell, the signal attenuation will be very serious;

The power register setting is wrong, the air speed setting is too high (the higher the air speed, the closer the
distance);

The low voltage of the power supply at room temperature is lower than the recommended value, the lower the
voltage, the lower the power output;

The poor matching degree of the antenna and the module or the quality of the antenna itself.
6.2 Module is easy to damage

Please check the power supply to ensure that it is within the recommended power supply voltage. If it exceeds the
maximum value, it will cause permanent damage to the module;

Please check the stability of the power supply, the voltage should not fluctuate greatly and frequently;

Please ensure anti-static operation during installation and use, and high-frequency components are electrostatically
sensitive;

Please ensure that the humidity during installation and use should not be too high, and some components are
humidity sensitive devices;

If there is no special requirement, it is not recommended to use at too high or too low temperature.
