Chapter 11 common problems

9.1 the transmission distance is not ideal

 When there is a direct communication obstacle, the communication distance will be correspondingly attenuated;

Temperature, humidity and co frequency interference will increase the packet loss rate of communication;

The ground absorbs and reflects radio waves, and the test effect near the ground is poor;

Sea water has a very strong ability to absorb radio waves, so the seaside test effect is poor;

If there are metal objects near the antenna or placed in the metal shell, the signal attenuation will be
very serious;

Power register setting error, air speed setting too high (the higher the air speed, the closer the distance);

At room temperature, the low voltage of the power supply is lower than the recommended value, and the lower
the voltage, the smaller the power generation;

The matching degree between the antenna and the module is poor or the quality of the antenna itself is poor.

9.2 module is easy to be damaged

 Please check the power supply to ensure that it is between the recommended power supply voltage. Exceeding
the maximum value will cause permanent damage to the module;
 Please check the stability of the power supply, and the voltage cannot fluctuate greatly and frequently;

please ensure anti-static operation during installation and use, and electrostatic sensitivity of
high-frequency devices;

Plase 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 it at too high or too low temperature.

9.3 bit error rate is too high

 If there is interference of the same frequency signal nearby, stay away from the interference source or modify
the frequency and channel to avoid interference;
 If the power supply is not ideal, it may also cause garbled code, and the reliability of the power supply
must be guaranteed;
 Poor or too long extension lines and feeders will also cause high bit error rate.
