FAQ:
Communication range is too short
-
The communication distance will be affected when an 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 the 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 the metal object or put in a metal case;
-
Power register was set incorrectly, the 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.
The module is easy to damage
-
Please check the power supply source, ensure it is 2.0V~3.6V, a voltage higher than 3.6V will damage the module;
-
Please check the stability of power source, the voltage cannot fluctuate too much;
-
Please make sure antistatic measure is taken when installing and using, high-frequency devices have electrostatic susceptibility;
-
Please ensure the humidity is within a limited range, some parts are sensitive to humidity;
-
Please avoid using modules under too high or too low temperature.
BER(Bit Error Rate) is high
-
There are co-channel signal interference nearby, please be away from interference sources or modify frequency and channel to avoid interference;
-
Poor power supply may cause messy code. Make sure that the power supply is reliable;
-
The extension line and feeder quality are poor or too long, so the bit error rate is high.
