Is there any power saving or sleep mode?

[Nathan-ma]

Hellol mates, I'm using a 3G module and I was wondering if I could use a AT+CSCLK=2 or something similar to put the board into sleep mode? if yes, this is implemented in the lib already (I try to look for it and couldn't find).

If not maybe I'm going to implement it myself. but first I would need to know where I could find the list of commands for the 3G version!

Thank you and have a great day!
