For functions 1 and 2 above, output low takes precedence, i.e., the AUX outputs low if any of the output low conditions are
met.
When all low conditions are not met, the AUX outputs high.
2
When the AUX output is low, it means that the module is busy and no working mode detection will be performed at this
time
When the module AUX output high level within 1ms, it will complete the mode switching work.
3
After the user switches to a new operating mode, at least 2ms of the rising edge of the AUX is required before the module
will actually enter that mode.
If the AUX stays high, then the mode switch will take effect immediately.
4
The module resets the user parameters when the user goes from mode 3 (sleep mode) to other modes or during reset,
during which the AUX output goes low.
5
Due to the characteristics of LoRa modulation method, the information transmission delay is much longer than FSK, such
as at 1.2kbps airspeed, the 100 bytes transmission delay is about 1.5 seconds, so it is recommended that customers should
not carry out large data transmission at low airspeed to avoid data loss caused by data buildup and abnormal
communication.
6 Working mode
