    DIO_7 pin to low level and DIO_13, DIO_14 pins to high level;Before turning off, set DIO_7, DIO_13, DIO_14 pins to low; The register configuration can be reinitialized when the chip is idle for greater stability.  Copyright ©2012–2021，Chengdu Ebyte Electronic Technology Co.,Ltd.

  • Page 10: Basic Application

    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.  Copyright ©2012–2021，Chengdu Ebyte Electronic Technology Co.,Ltd.

  • Page 11: Module Is Easy To Damage

    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.  Copyright ©2012–2021，Chengdu Ebyte Electronic Technology Co.,Ltd.
