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.

Due to the characteristics of the LoRa modulation method, the information transmission delay is much longer than that of FSK.
For example, at 2.4kbps airspeed, the 100-byte transmission delay is about 1.5 seconds. It is recommended that customers do not
transmit large amounts of data at low airspeeds, so as to avoid communication abnormalities caused by data loss due to data
accumulation.
