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 seriously affected when the antenna is near metal object or put in a metal case;
 Power register was set incorrectly or 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 our recommendation, the lower the voltage,
the lower the transmitting power;
 Due to antenna quality or poor matching between antenna and module.
6.2 Module is easy to damage
 Please check the power supply source, ensure it is 1.8V~3.6V, voltage higher than 3.6V will damage the module;
