FAQ 

5.1

 

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. 

 

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 d istance). 

 

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.
