2.14.1 Operating sequences
2.14.1.1 Power ON
Once the module supplied, the application must set the ON/OFF signal to high
to start the module power ON sequence. The ON/OFF signal must be hold for
1000ms minimum. After this time, an internal mechanism keeps it on hold.
During the power ON sequence, an internal reset is automatically performed by
the module for 240ms (typical). During this phase, any external reset should be
avoided. Once the initialisation is complete (timing is SIM and network
dependent) the AT interface answers « OK » to the application
. For further
details, please check the AT commands manual (+WIND, +WAIP)

For this, the application has to send AT↵. If the application manages hardware flow control, the
AT command can be sent during the initialisation phase. Another solution is to use the +WIND
command to get an unsolicited status from the module.
