    The receivers under target channel will receive data.. Only 1 data packet length is supported for fixed transmission (refer to electrical parameters); If the data exceeds 1 data packet length, it will be sub-packed automatically.

    AUX Pin can be used as indication for wireless send & receive buffer and self-check. It can indicate whether there are data that are yet to send via wireless way, or whether all wireless data has been sent through UART, or whether the module is still in the process of self-check initialization. Copyright ©2012–2020, Chengdu Ebyte Electronic Technology Co., Ltd.
  • Page 11 Notes: When AUX = 1, it does not mean that all the UART data of the module have been transmitted already, perhaps last packet data still transmission. 【Configuration procedure of module】 Only happened when power-on resetting or exiting sleep mode.

  • Page 12 When the user switches to other operating modes from mode 3 (sleep mode) or it ’s still in reset process, the module will reset user parameters, during which AUX outputs low level. Copyright ©2012–2020, Chengdu Ebyte Electronic Technology Co., Ltd.

  • Page 13: Operating Mode

    This operation is very flexible and efficient. It is totally designed on the basis of the user MCU’s convenience, at the same time the work load and power consumption of the whole system has been reduced and the efficiency of whole system is largely improved.
