<lac> - location area code; if #CSURVF last setting is 0, <lac> is a decimal
number, else it is a 4-digits hexadecimal number.
<cellStatus> - string type; it is the cell status.
CELL_SUITABLE - C0 is a suitable cell.
CELL_LOW_PRIORITY - the cell is low priority based on the received system
information.
CELL_FORBIDDEN - the cell is forbidden.
CELL_BARRED - the cell is barred based on the received system information.
CELL_LOW_LEVEL - the cell <rxLev> is low.
CELL_OTHER - none of the above e.g. exclusion timer running, no BCCH
available…etc.
In 4G (partly implemented)
Currently work only if module camped on LTE cell.
For serving cell:
earfcn: <earfcn> rxLev: <rxLev> mcc: <mcc> mnc: <mnc> cellId: <cellId> tac:
<tac>
For neighbor cell:
earfcn: <earfcn> rxLev: <rxLev> cellId: <cellId>
Where:
<earfcn> - E-UTRA Assigned Radio Channel
<tac> - Tracking Area Code. if #CSURVF last setting is 0, <cellId> is a decimal
number, else it is a 4-digits hexadecimal number
Lastly, the
#CSURV output ends in two ways, depending on the last #CSURVF
setting:
if
#CSURVF=0 or #CSURVF=1
The output ends with the string:
Network survey ended
if
#CSURVF=2
the output ends with the string:
Network survey ended (Carrier: <NoARFCN> BCCh: <NoBCCh>)
Where:
<NoARFCN> - number of scanned frequencies
<NoBCCH> - number of found BCCh
