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.

Seawater 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 the recommended value, 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 within the recommended value, voltage higher than that 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.
