FAQ
6.1 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
distance);
 The power supply low voltage under room temperature is lower than 2.5V, the lower the voltage, the lower the
transmitting power;
 Due to antenna quality or poor matching between antenna and module.
