Syntax: Command syntax: AT+CCED=<mode>[, <requested dump>]
Command Possible Responses
AT+CCED=? +CCED: (0-2),(1-15)
OK
AT+CCED? +CCED: 0,13
OK
AT+CCED=0
Note: one time, dump default (8, 4, and 1)
+CSQ: 15, 99
+CCED: 0,0,1,125,4,65535,6,,0,,,-107,-32,-63
OK
AT+CCED=0,1
Note: one time, dump main cell
+CCED: 1,725,4,65535,6,,0,,,-104,-35,-63
OK
AT+CCED=1,8
Note: Start automatic snapshots and
dump <rssi>.
+CSQ: 18, 99
Note: No OK response. New +CSQ response output every 5
seconds.
AT+CCED=2,8 OK
Note: Stop automatic snapshots of <rssi>.
AT+CCED=0,2
Note: one time, dump neighbor cells.
Neighbor cells must be dumped
separately.

OK
Note: 18 neighbor cells are present. The first neighbor cell band
class is 0, its PilotPN is 268, and its frequency assignment is
384.
If the <requested dump> parameter is not specified, the <requested dump> value from the previous +CCED command will be
used. If no previous +CCED <requested dump> value is available, a default value of 13 (8, 4, and 1) will be used.
For <requested dump> 4, 2, and 1, the requested information is output using the unsolicited +CCED response. Place holders
are used in the +CCED output for fields that cannot be measured or are not meaningful in the current mode of operation. In
this case, consecutive commas will be present in the output. There are also several optional parameters ([]) that are not
displayed in analog mode and will result in place holders in the +CCED command output. Automatic snapshots of these
dumps are not supported during communication or registration.
For <requested dump> 1, the first value output in the unsolicited +CCED response is the +CCED command specified <mode>
(0, 1, or 2). The value displayed for Ec/Io is the index of the Active set in 0.5dB steps from 0 (0dB) to 63 (-31.5dB). For
example: 0 = 0dB, 1 = 0.5dB, 2 = 1dB, … 62 = 31dB, 63 = 31.5dB. The value displayed for <Rx power>, <Tx power>, and <Tx
Adj> is in terms of dBm.
For <requested dump> 8, the information is output using the unsolicited +CSQ response. The 07.07 format of the +CSQ
response is respected. However, the <fer> portion of the +CSQ response is not evaluated by this dump request so the <fer>
value will always be 99. Automatic snapshots are supported in idle mode and during communication.
The combination of multiple <requested dump> values (addition of the values) in a single +CCED command is supported with
the exception of <requested dump> 2. The <requested dump> 2 value must be use by itself and not in combination with other
dump request values.
Either or both the +CCED and +CSQ responses are used for output depending upon the <requested dump> value. Activation
or deactivation of a +CCED response flow will not affect an existing +CSQ response flow. Likewise, activation or deactivation
of a +CSQ response flow will not affect an existing +CCED response flow.
