Hi Zineddine
I don’t know what parameters are set by AT + QNBIOTRAI?
ENTER PSM is just that the module modem enters PSM mode, but the module AP does not enter PSM mode.

3

The module enters the Sleep Mode when Sleep is enabled, no network activity and kernel “stays” in the idle task
User can not control ( only enable/disable ) Sleep Mode - kernel PSM manager control this

4

on a other post you told me to put the AT + QNBIOTRAI=1 before sending a message so the device will go in sleep after sending directily is that still correct?

regards

Hi Zineddine
You can have a try, execute AT + QNBIOTRAI = 1 before sending data every time.
