Syntax: Command syntax: AT+CCED=[, ]
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 . +CSQ: 18, 99
Note: No OK response. New +CSQ response output every 5 seconds.
AT+CCED=2,8 OK
Note: Stop automatic snapshots of .
AT+CCED=0,2
Note: one time, dump
neighbor cells. Neighbor
cells must be dumped
separately. +CCED:18,0,268,384,0,272,384,0,296,384,0,8,384,0,48,384,0,248,384,0
,164,384,0,16,384,0,12,384,0,224,384,0,108,384,0,476,384,0,472,384,0,
76,384,0,292,384,0,300,384,0,312,384,0,308,384
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.
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
If the parameter is not specified, the value from the previous +CCED
command will be used. If no previous +CCED value is available, a default value of 13 (8,
4, and 1) will be used.
For 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 AMPS 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 8, the information is output using the unsolicited +CSQ response. The 07.07 format
of the +CSQ response is respected. However, the portion of the +CSQ response is not evaluated by
this dump request so the value will always be 99. Automatic snapshots are supported in idle mode and
during communication.
The combination of multiple values (addition of the values) in a single +CCED command
is supported with the exception of 2. The 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
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.
