9.2 Module is easy to damage

Please check the power supply source, ensure it is 2.0V~3.6V, voltage higher than 3.6V 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.
9.3 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;
