8.11 AT^MONP Monitor Neighbor Cells
Description: The AT^MONP supplies information for up to six neighbor cells. There are two ways to retrieve
the information: 1) by request using the execute command or 2) automatically every <period>
seconds by using the write command. To stop the periodic presentation type “AT” or “at”.
Syntax: Test Command: AT^MONP=?
Response: ^MONP:(list of supported <period>s)
OK
Exec Command: AT^MONP
Response: See: Section 8.11.1, AT^MONP responses
OK
Write Command: AT^MONP=<period>
Response: See: Section 8.11.1, AT^MONP responses
OK
ERROR
+CME ERROR: <err>
Parameter:
<period> Display Period in Seconds
1...254
Notes:
• During a connection, some neighbor cell parameters cannot be updated. Therefore, the parameters MCC, MNC,
C1 and C2 equal zero (see AT^MONP Responses) until the connection is released.
• To some extent, the cell monitoring command AT^SMONC covers the same parameters. The receiving level, for
example, can be queried with both commands. Yet the resulting values may be slightly different, even though
obtained over a time period of a few seconds. This is quite normal and nothing to worry about, as the cell
information is permanently updated.
• For compatibility with earlier products and to support legacy applications, any input character may be used to
stop the output in certain cases (depending on the settings of AT+IPR).
• This command is not PIN protected.
• This command is not supported in airplane mode.
