11. Timing parameters
This section describes the behaviour of the Calypso module during reset, sleep and wake-up
operations.
11.1. Hard reset
A hard reset on the Calypso module is done by asserting a low on the
. On hard-
reset, the module reloads the application from the sFlash after verifying the image to ensure
the integrity of the application. This contributes towards higher start up times of the applica-
tion.

11.2. Soft reset
A software reset is made available through the AT command
AT+reboot
(see section
). In
this case the module restarts from the reset vector. The exact same process happens after
a wake-up signal from sleep mode.

It is recommended to use the AT command to reboot the device instead of a
falling edge on the
pin whenever applicable.
Use
AT+stop
and
AT+start
to restart the network processor.
The fast/auto connect features ensure immediate connect to AP on
reboot/wake-up.
