10.1 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).

When the power supply at room temperature is lower than the recommended low voltage, the lower the voltage is, the lower the

transmitting power is.
Due to antenna quality or poor matching between antenna and module.


10.2 Module is easy to damage

Please check the power supply and ensure it is within the recommended range. Voltage higher than the peak will lead to a

