Faq; Communication Distance Is Too Short; Module Is Easy To Damage; Ber(Bit Error Rate) Is High - Ebyte EA01-S User Manual

Chengdu Ebyte Electronic Technology Co., Ltd
necessary, appropriate isolation and shielding can be done;
The mounting structure of antenna has a great influence on the performance of the module. It is necessary

to ensure that the antenna is exposed, preferably vertically upward. When the module is mounted inside
the case, use a good antenna extension cable to extend the antenna to the outside;
The antenna must not be installed inside the metal case, which will cause the transmission distance to be

greatly weakened.

7 FAQ

7.1 Communication distance 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 recommended value, the lower the

voltage, the lower the transmitting power;
Due to antenna quality or poor matching between antenna and module.


7.2 Module is easy to damage

Please check the power supply source, ensure it is between the recommended supply voltage, voltage

higher than the maximum will damage the module.
Please check the stability of power source, the voltage cannot fluctuate too much;

Please make sure antistatic measure are taken 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.


7.3 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.
