8. FAQ

8.1 Communication range is too short

 The communication distance will be affected when obstacle exists;

Data lose rate will be affected by temperature, humidity and co -channel interference;
 The ground will absorb and reflect wireless radio wave, so the performance will be poor when testing near ground;
 Sea water has great ability in absorbing wireless radio wave, so performance will be poor when testing near the sea;

The signal will be affected when the antenna is near metal object or put in a metal case;

Power register was set incorrectly, air data rate is set as too high (the higher the air data rate, the shorter the distance);
 The power supply low voltage under room temperature is lower than 2.5V , the lower the voltage, the lower the
transmitting power;

Due to antenna quality or poor matching between antenna and module.

8.2 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.

8.3 BER(Bit Error Rate) is high

 There are co-channel signal interference nearby, please be away from interference sources or modify
