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 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;

Please check the stability of power source, the voltage cannot fluctuate too much;

Please make sure anti-static operation when installing and using, high frequency devices have electrostatic

susceptibility;

Please ensure the humidity is within limited range, some parts are sensitive to humidity;

Please avoid using modules under too high or too low temperature.

6.3 BER(Bit Error Rate) 1s high

There are co-channel signal interference nearby, please be away from interference sources or modify

frequency and channel to avoid interference;

The clock waveform on SPI is not standard, check whether there is interference on the SPI line, and the SPI bus line

should not be too long;

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.

Production guidance

This product is a SMD module. When soldering the module, the soldering personnel must work in accordance with

the anti-static operation specification,

This product is an electrostatic sensitive product. If the module is not welded according to the specification, the

module may be permanently damaged.
