#AUTOBND - Automatic Band Selection
0 - disables automatic band selection at next power-up (factory default)
1 - enables automatic band selection at next power-up
2 - enables automatic band selection in four bands (at 850/1900/900/1800)
differently from previous settings it takes immediate effect
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>
