Hi,
I am setting “AT+CEREG=4” to enable unsolicited result codes. When I run “AT+CEREG?” I get the following responses.

+CEREG: 2,“00000000”,“01100000”
+CEREG: 2,“00000000”,“01100000”
+CEREG: 3,“00000000”,“01100000”

Why does the modem doesn’t display the codes and only display a sequence of commas after +CEREG: 2 and +CEREG: 3 instead?

Are you mean PSM timer? and have you enabled it?

I don’t know how to enable it. How do I enable the PSM timer?

Not very clear what’s codes you mean.
for my understanding, this shows devcie not register to network. so there is no other parameters like RAT mode, freq…
