#AUTOBND - Automatic Band Selection
Note : Band selection will be followed #BND setting at next power-up when
AT#AUTOBND=0
or
AT#AUTOBND=1
is issued.
AT#AUTOBND?
Read command returns whether the automatic band selection is enabled or
not in the form:
#AUTOBND: <value>
AT#AUTOBND=?
Test command returns the range of supported values for parameter
<value>
.
3.5.5.1.43.
RTC Status - #RTCSTAT
#RTCSTAT - RTC Status
AT#RTCSTAT=
<status>
Set command resets the RTC status flag.
Parameter:
<status>
0 - Set RTC Status to
RTC HW OK
Note: the initial value of RTC status flag is
RTC HW Error
and it doesn’t change
until a command
AT#RTCSTAT=0
is issued.
Note: if a power failure occurs and the buffer battery is down the RTC status flag
is set to
1
. It doesn’t change until command
AT#RTCSTAT=0
is issued.
AT#RTCSTAT?
Read command reports the current value of RTC status flag, in the format:
#RTCSTAT: <status>
AT#RTCSTAT=?
Test command returns the range of supported values for parameter
<status>
3.5.5.1.44.
GSM Antenna Detection - #GSMAD
#GSMAD - GSM Antenna Detection
AT#GSMAD=
<mod>,
[<urcmode>
[,<interval>
[,<detGPIO>
[,<repGPIO>]]]]
Set command sets the behaviour of antenna detection algorithm
Parameters:
<mod>
0 - detection algorithm not active
1 - detection algorithm active; detection is started every
<interval>
period, using
<detGPIO>
for detection.
2 - triggers the new measurement of the antenna presence, reporting the result in
the format:
#GSMAD: <presence>
where:
<presence>
0 - antenna connected.
1 - antenna connector short circuited to ground.
2 - antenna connector short circuited to power.
