9.FAQ

Communication range is too short

9.1
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.


Module is easy to damage

9.2
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.


Bit error rate is too high

9.3
 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;
