7 FAQ
7.1 Communication distance 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 recommended value, the lower the
voltage, the 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.
