8 FQA
8.1 The transmission distance is not ideal

When there is a straight-line communication barrier, the communication distance will be attenuated accordingly;

Temperature, humidity, same frequency interference, will lead to increased loss rate of communication;

Ground absorption, reflection of radio waves, close to the ground test results are poor;

The sea water has a strong ability to absorb radio waves, so the seaside test effect is poor;

There is a metal object near the antenna, or placed in a metal shell, the signal attenuation will be very serious;

The power register is set incorrectly and the air rate is set too high (the higher the air rate, the closer the distance);

The low voltage of the power supply at room temperature is lower than the recommended value, and the lower the
voltage, the lower the power;

Use the antenna to match the module poorly or the quality of the antenna itself is a problem.
8.2 Module is easy to be damaged

Please check the power supply to ensure that between the recommended supply voltage, if the maximum value is
exceeded, the module will be permanently damaged;

Please check the stability of the power supply, the voltage can not fluctuate significantly and frequently;

Make sure that the installation process anti-static operation, high-frequency device static sensitivity;

Make sure that the humidity of the installation process should not be too high, some components are humidity
sensitive devices;

If there are no special needs, it is not recommended to use at high or low temperatures.
8.3 BER(Bit Error Rate) is high

There is the same frequency signal interference nearby, away from the source of interference or modify the
frequency, channel to avoid interference;

The clock waveform on the SPI is not standard, check whether there is interference on the SPI line, the SPI
bus line should not be too long;

The power supply is not ideal may also cause garbled code, it is necessary to ensure the reliability of the
power supply;

Extension cords, feeders of poor quality or too long, will also result in a high error rate.
