Enter PSM on WP7702

Hello,
someone can share the steps to set PSM (at commands sequance) on WP7702?

Starting situation is: my module is normally configured to enter ULPM. (AT!POWERWAKE=2,38,1).

I also need a PSM mode i can use instead of ULPM.

Regards,
Gianmaria

You can see here

You need to set +cpsms and wait for network reply.

Also you need need to run the wakeup_app.rar to let the module stay awake while removing usb cable.
