6 Trouble Shooting
6.1 Unsatisfactory Transmission Distance
1.
When there is a linear communication obstacle, the communication distance will be correspondingly weakened.
Temperature, humidity, and co-channel interference will lead to an increase in communication packet loss rate.
The performance of ground absorption and reflection of radio waves will be poor when the module is tested close
to the ground.
2.
Seawater has a strong ability to absorb radio waves, so the test results by the seaside are poor.
3.
The signal attenuation will be very obvious if there is a metal near the antenna or the module is placed inside the
metal shell.
4.
The incorrect power register set or the high data rate in an open-air may shorten the communication distance. The
higher the data rate, the closer the distance.
5.
The low voltage of the power supply is lower than the recommended value at ambient temperature, and the lower
the voltage, the smaller the power is.
6.
The unmatchable antennas and modules or the poor quality of the antenna will affect the communication distance.
6.2 Vulnerable Module
1.
Please ensure the supply voltage is between the recommended values. The module will be permanently damaged
if the voltage exceeds the maximum value. Please ensure a stable power supply and no frequently fluctuated
voltage.
2.
Please ensure the anti-static installation and the electrostatic sensitivity of high-frequency devices.
3.
Due to some humidity-sensitive components, please ensure suitable humidity during installation and application. If
there is no special demand, it is not recommended to use at too high or too low a temperature.
6.3 High Bit Error Rate
1.
There are co-channel signal interferences nearby. It is recommended to be away from the interference sources or
modify the frequency and channel to avoid interferences.
2.
The unsatisfactory power supply may also cause garbled. It is necessary to ensure the power supply’s reliability.
3.
If the extension wire or the feeder wire is of poor quality or too long, the bit error rate will be high.
