5.6.4 Precautions
AUX matters need attention
The above function 1 and function 2, the output low level priority, that is, meet any one of the output low
level conditions, AUX output low level;
When all low level conditions are not satisfied, AUX outputs a high level.
When AUX output is low level, the module is busy and no working mode detection will be conducted at this
time;
When the module AUX is output within 1ms after the high level, the mode switching work will be completed.
After the user switches to the new working mode, he needs to rise the AUX for at least 2ms before the
module will really enter this mode;
If the AUX is always at a high level, then the mode switch takes effect immediately.
The user enters another mode from mode 3 (sleep mode), or during the reset process, the module resets the
user parameters, during which the AUX outputs a low level.
Due to the characteristics of LoRa modulation mode, the information transmission delay is much longer than
that of FSK. For example, at 1.2 kbps empty speed, the 100-byte transmission delay is about 1.5 seconds. It is
suggested that customers do not carry out large data transmission at low altitude speed, so as to avoid
abnormal communication caused by data loss caused by data accumulation.
