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;
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 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.
