lower the transmitting power;
 Due to antenna quality or poor matching between antenna and module.

7.2 Module is easy to damage

 Please check the power supply source, ensure it is between the recommended supply voltage, voltage higher than
the maximum will damage the module.
 Please check the stability of power source, the voltage cannot fluctuate too much.
 Please make sure antistatic measure are taken when installing and using, high frequency devices have electrostatic
susceptibility。
 Please ensure the humidity is within limited range, some parts are sensitive to humidity.
 Please avoid using modules under too high or too low temperature.

7.3 BER(Bit Error Rate) is high

 There are co-channel signal interference nearby, please be away from interference sources or modify frequency and
channel to avoid interference;

Poor power supply may cause messy code. Make sure that the power supply is reliable;

The extension line and feeder quality are poor or too long, so the bit error rate is high.
