8.3 AT^MONP Monitor neighbour cells
Test command
AT^MONP=?
Response
^MONP: (list of supported < period >s) OK
Write command
AT^MONP=[<period>]
This command can be used to retrieve information of up to six neighbour
cells automatically every n seconds. It is cancelled by any character sent
to the serial port except if autobauding is enabled (+IPR=0). Then type
character ´a´ to abort.

Note
· Cell information can be issued in the form of unsolicited result codes
(related to <period>), or it can be queried directly using the Execute
command AT^MONI. In the first case, the ME activates its RING line
(Logic “1”) for one second to send the URC to the connected applica-
tion. In the second case, the RING line does not change.

· Due to the fact that not all necessary information of the neighbour cells
can be decoded during a connection, there are several constraints to
be considered:
be considered:
-
Only neighbour cells that have already been visible in IDLE mode
will be further updated, as long as they are still included in the list.

-
Though new neighbour cells can be added to the list (e.g. due to
handover), their C1 and C2 parameters cannot be displayed until
the connection is released. In this case “-“ is presented for C1 and
C2.
