8.10 AT^MONI Monitor Idle Mode and Dedicated Mode
Description: The AT^MONI command supplies information of the serving/dedicated cell. There are two ways
to retrieve the information: once on request by using the execute command or automatically
every <period> seconds by using the write command. To stop the periodic presentation type “AT”
or “at”.
Syntax: Test Command: AT^MONI=?
Response: ^MONI:(list of supported <period>s)
OK
Exec Command: AT^MONI
Response: See: Section 8.10.1, AT^MONI responses
OK
Write Command: AT^MONI=<period>
Response: See: Section 8.10.1, AT^MONI responses
OK
ERROR
+CME ERROR
Parameter:
<period>
Display period in seconds
1...254
Notes:
• The two header lines (see Section 8.10.1, AT^MONI responses) are output after every ten data lines.
• The length of following output lines exceeds 80 characters. Therefore a terminal program may draw a carriage
return on a screen. However, this is not part of the response.
• The parameters LAC and cell are presented as hexadecimal digits, the remaining parameters are composed of
decimal digits.
If the radio cell changes during a connection, the parameters PWR, RXLev and C1 of the ‘Serving Cell’ part
cannot be updated under certain conditions.
• If the BS supports frequency hopping during a connection, the dedicated channel (parameter chann) is not
stable. This mode is indicated by chann = ‘h’.
• 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.
