Metal objects near antennas, or placed in metal shells, attenuated signals.very serious;

Incorrect power register setting, excessive air rate (air rate)the higher the distance, the closer;

At room temperature, the lower the voltage, the lower the power.


7.2 Module is easy to damage

Check the power supply to ensure that permanent damage to the module occurs between recommended supply

voltages, if exceeded;
Please check the stability of the power supply. The voltage cannot fluctuate significantly and frequently.

Please ensure anti-static operation during installation and high frequency device electrostatic sensitivity;

Please ensure that the installation process is not too humid. Some components are humidity sensitive.

If there is no special requirement, it is not recommended to use it at too high and too low temperatures.


7.3 The error rate is too high

There is interference from the same frequency signal nearby, away from the source of interference, or from

modifying frequency and channel;
The clock waveforms on the UART are not standard. Check for interference on the UART line;

Poor power supply may also cause confusion. Be sure to ensure the reliability of the power supply;
