[Note]
: When AUX=1, it does not mean that all serial port data of the module has been transmitted through wireless; It may be
the case that the last data packet is being transmitted.
5.6.3 The module is being configured
Only when resetting and exiting sleep mode;
5.6.4 Notes for AUX
No.
Notes for AUX
1
For function 1 (5.6.1) & function 2 ( (5.6.2) mentioned above, the priority should be given to the one with low level output,
which means as long as any output low level condition is met, AUX will output low level; Only when none of the output
low level condition is met, AUX will outputs high level.
2
When AUX outputs low level, it means the module is busy & it won’t conduct working mode checking.
Within 1ms since AUX outputs high level, the module working mode switch will be completed.
3
After switching to new working mode, module will not work in the new mode immediately until AUX rising edge lasts for
2ms.
If AUX is always at high level, then the mode switch will take effect immediately;
4
When the user switches to other working modes from mode 3 (sleep mode) or it is still in reset process, the module will
reset user parameters, during which AUX outputs low level.
5
Due to the characteristics of the LoRa modulation method, the information transmission delay is much longer than FSK.
To avoid communication abnormalities caused by data accumulation and data loss, customer is suggested not to transmit
large amounts of data at low air data rate.
