FAQ

10.1 Communication range is too short

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

10.2 Module is easy to damage

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