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.
