5.6.2 Wireless transmission indication

Buffer empty: The data in the internal 512-byte buffer is written to the wireless chip (automatic sub-packet).

When AUX=1, the user continuously initiates data less than 512 bytes without overflow. When AUX=0, the buffer is not empty:

the data in the internal 512-byte buffer has not been written to the wireless chip and the transmission is started. At this time, the
module may be waiting for the end of the user data to time out, or the wireless packet transmission is in progress. .
[Note]: When AUX=1, it does not mean that all serial port data of the module has been transmitted wirelessly, or the last packet

of data may be being transmitted.

5.6.3 The module is being configured

Only at reset and when exiting sleep mode


5.6.4 AUX Notes

For the above functions 1 and 2, the output low level is given priority, that is, if any one of the output low level conditions is

satisfied, the AUX outputs the low level; when all the low level conditions are not satisfied, the AUX outputs the high level.
When AUX outputs a low level, it means that the module is busy, and the working mode detection will not be performed at this

time; when the module AUX outputs a high level within 1ms, the mode switching work will be completed.
After the user switches to the new working mode, the module will enter this mode at least 2ms after the rising edge of AUX; if

AUX is always at a high level, the mode switching will take effect immediately.
When the user enters other modes from mode 3 (sleep mode) or during the reset process, the module will reset the user

parameters, during which AUX outputs a low level.
