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.
Response

Parameter
<period> 1 – 254 Display period in seconds

Note
The cell information can be issued in the form of unsolicited result
codes (related to <period>), or it can be queried directly using the Exe-
cute command AT^MONI. In the first case, the ME activates its RING
line (Logic “0”) for one second to send the URC to the connected appli-
cation. 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 the connection, there are several constraints to
be considered:
- Only neighbour cells of the serving cell the MS was camping on
during call setup will be further updated, as long as they are visible.
- New neighbour cells that have been added to the list (e.g. in result
of a handover), are not made visibile via the AT^MONP command
until the connection is released.
