7.6.2 Reset sequence

To activate the « emergency » reset sequence, the RESET signal has to be set to

low for 500 µs minimum.

As soon as the reset is complete, the AT interface answers « OK » to the

application. For this, the application has to send

↵

If the application manages hardware flow control, the AT command can be sent

during the initialisation phase. Another solution is to use the AT+WIND

command to get an unsollicited status from the modem.

For further details, refer to AT commands documentation [1].
