2.5.3.2 Reset sequence
To activate the « emergency » reset sequence, the RSTEXTN signal has to be set to low for
500s minimum.
As soon as the reset is complete, the AT interface answers « OK » to the application. For
this, the application has to send AT. If the application manages hardware flow control, the
AT command can be sent during the initialization phase. Another solution is to use the
AT+WIND command to get an unsolicited status from the module.
For further details, refer to AT commands documentation [4].
