It can indicate whether there are data that are not sent yet 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. 5.6.1 Indication of UART output To wake up external MCU Copyright ©2012–2020, Chengdu Ebyte Electronic Technology Co., Ltd. -
Page 10: Indication Of Wireless Transmitting
After switching to new operating mode, it will not work in the new mode immediately until AUX rising edge lasts for 2ms . If AUX stays on the high level, the operating mode switch can be affected immediately. Copyright ©2012–2020, Chengdu Ebyte Electronic Technology Co., Ltd. - Page 11 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.

Page 12: Operating Mode
This operation mode is very flexible and efficient, and is designed according to the user's MCU's operation convenience, and can reduce the workload of the entire system as much as possible, improve system efficiency, and reduce power consumption.

Page 13: Normal Mode（Mode 0
“Sleep-Monitor”working mode(polling); Set different wake-up time, the module has different receiving response time (max 2s) and different average power consumption(min 30uA); Users need to strike a balance between communication latency and average power consumption. Copyright ©2012–2020, Chengdu Ebyte Electronic Technology Co., Ltd. -
Page 14: Sleep Mode（Mode 3
When entering other modes from the sleep mode, the module will reconfigure the parameters. During Note the configuration process, AUX keeps low level; after that, AUX outputs high level, so it is recommended that the user detect the AUX rising edge.
