Chengdu Ebyte Electronic Technology Co., Ltd. E01-ML01S User ManualCopyright ©2012–2018，Chengdu Ebyte Electronic Technology Co.,Ltd. 76.FAQ6.1 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 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 d istance). The power supply low voltage under room temperature is lower than 2.5V, the lower the voltage, the lower thetransmitting 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 2.0V~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 antistatic measure are taken when installing and using, high frequency devices have electrostaticsusceptibility. 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) is high There are co-channel signal interference nearby, please be away from interference sources or modify frequency andchannel 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;7.Soldering guidance7.1 Reflow soldering temperature
