 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 2.5V, the lower the voltage, the lower the
transmitting power.
 Due to antenna quality or poor matching between antenna and module.
9.2 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 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.
9.3 BER(Bit Error Rate) is high
 There are co-channel signal interference nearby, please be away from interference sources or modify frequency a nd
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;
10 Production guidance
This type is DIP module, when the welder welds the module, he must be welding according to the anti-static regulation.
This product is allergic to static, randomly welding the module will have the chance of damaging it permanently.
