3.5.7.6 Easy Scan® Extension AT Commands

Note: it is strongly suggested to issue all the Easy Scan® Extension AT commands with NO

SIM inserted, to avoid a potential conflict with normal module operations, such as “incoming

call”, “periodic location update, “periodic routing area update” and so on.

3.5.7.6.1 Network Survey - #CSURV

#CSURV - Network Survey

AT#CSURV[=

[<s>,<e>]]

Execution command allows to perform a quick survey through channels

belonging to the band selected by last #BND command issue, starting from

channel <s> to channel <e>. Issuing AT#CSURV<CR>, a full band scan is

performed.

Parameters:

<s> - starting channel

<e> - ending channel

After issuing the command the device responds with the string:

Network survey started…

and, after a while, a list of informations, one for each received carrier, is

reported, each of them in the format:

(For BCCH-Carrier)

arfcn: <arfcn> bsic: <bsic> rxLev: <rxLev> ber: <ber> mcc: <mcc>

mnc: <mnc> lac: <lac> cellId: <cellId> cellStatus: <cellStatus>

numArfcn: <numArfcn> arfcn: [<arfcn1> ..[ <arfcn64>]]

[numChannels: <numChannels> array: [<ba1> ..[<ba32>]] [pbcch:

t3168: <t3168> t3192: <t3192> drxmax: <drxmax> ctrlAck: <ctrlAck>

bsCVmax: <bsCVmax> alpha: <alpha> pcMeasCh: <pcMeasCh>]]]

where:

<arfcn> - C0 carrier assigned radio channel (BCCH - Broadcast Control

Channel)

<bsic> - base station identification code; if #CSURVF last setting is 0,

<bsic> is a decimal number, else it is a 2-digits octal number

<rxLev> - decimal number; it is the receiption level (in dBm)

<ber> - decimal number; it is the bit error rate (in %)

<mcc> - hexadecimal 3-digits number; it is the mobile country code

<mnc> - hexadecimal 2-digits number; it is the mobile network code
