PLS63-W: why is AT-CPOL=? failing? | Telit Cinterion IoT Developer Community

May 9, 2023 - 2:53pm, 215 views

As in the subject, with PLS63-W I observe the following behavior:

ATI
Cinterion
PLS63-W
REVISION 01.202

OK
AT+CEER=0
OK
AT+CMEE=2
OK
AT+CPOL=?
ERROR
AT+CEER
+CEER: No cause information available

OK

What can be the reason? What else should/can I check?
