Command
Possible Responses
AT+CCED=0,9
+CSQ: 15, 99
+CCED: 0,160,69,101,6,144,2690,2,18,-85,-51,-63
OK
AT+CCED=1,8
Note: Start automatic snapshots and
dump <rssi>.
OK
+CSQ: 18, 99
Note: +CSQ response output every 5 seconds.
AT+CCED=2
OK
Note: Stop automatic snapshots.
AT+CCED=,,1
OK
+CSQ: 18, 99
Note: New +CSQ response output when change in
RSSI equals or exceeds <CsqStep>
AT+CCED=1,9
Note: Start automatic snapshots and
dump cell environment and <rssi>
OK
+CSQ: 15, 99
+CCED: 0,160,69,101,6,144,2690,2,18,-85,-51,-63
Values: <mode>
0 Requests a single snapshot of cell data
1 Start automatic snapshot mode. The unsolicited responses +CCED and/or +CSQ
will be used to return the requested information.
2 Stop automatic snapshot mode
<requested dump> This parameter is summation of one or more of the following values:
1 Main Cell Indication
2 Main Cell RSSI Indication (RxLev) from 0 to 31 and frame error rate. Set the
AT+CSQ command description for more information.
<CsqStep>
0 Unsolicited +CSQ reports due to changing RSSI levels are disabled.
1-5: Whenever the RSSI changes by this amount or more, an unsolicited +CSQ report
is generated.
Notes: The CCED response format is <band class>, <Channel #>, SID, NID, <Base Station P Rev>,<Pilot
PN offset>, <Base Station ID>, <Slot cycle index>, <Ec/Io>, <Rx power>, <Tx power>, <Tx Adj> in
units of dBm.
<band_class> values are 0 for cellular band (800 MHz) or 1 for PCS band (1900 MHz).
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 units of dBm.
If the <requested dump> parameter is not specified, the <requested dump> value from the most
recent invocation of the +CCED command with an explicit <requested dump> value will be used.
If no previous +CCED <requested dump> value is available, a value of 9 (8 and 1) will be used.
For <requested dump> 8, the information is output using the unsolicited +CSQ response. The
07.07 format of the +CSQ response is respected. Automatic snapshots are supported in idle
mode and during communication.
Either or both the +CCED and +CSQ responses are used for automatic snapshot output
depending upon the <requested dump> value at the time the snapshot activation was
requested.
