6.3 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;

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.
