AT#CSURV[=[<s>,<e>]]
Execution command performs a quick survey on 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. The command responds with the following
string:
Network survey started...
After a while, a list of network survey information text lines, one for each received carrier, is
reported. The format of network survey information text lines depends on technology (2G or 4G)
and BCCH (BCCH-Carrier or non BCCH-Carrier).
The #CSURV output ends in two ways, depending on the last #CSURVF setting.
If AT#CSURVF=0 or AT#CSURVF=1 the output will end with the string:
• Network survey ended
If AT#CSURVF=2 the output will end with the string:
• Network survey ended (Carrier: <NoARFCN> BCCh: <NoBCCh>)
The network survey information text lines are described in the Additional info sections.
