where:
<presence>
0 - antenna connected.
1 - antenna connector short circuited to ground.
2 - antenna connector short circuited to power.
3 - antenna not detected (open).
<urcmode> - URC presentation mode. It has meaning only if <mod> is 1.
0 - it disables the presentation of the antenna detection URC
1 - it enables the presentation of the antenna detection URC, whenever the antenna
detection algorithm detects a change in the antenna status; the unsolicited
message is in the format:
#GSMAD: <presence>
where:
<presence> is as before
<interval> - duration in seconds of the interval between two consecutive antenna
detection algorithm runs (default is 120). It has meaning only if
<mod> is 1.
1..3600 - seconds
<detGPIO> - defines which GPIO shall be used as input by the Antenna Detection
algorithm (default 13)..
Valid range is “any input pin number” (see “Hardware User Guide”).
<repGPIO> - defines which GPIO shall be used by the Antenna Detection
algorithm to report antenna condition. Value 0 means that no report is
made using GPIO (default 0). It has meaning only if <mod> is 1.
0 - no report is made using GPIO
Valid range is “any output pin number” (see “Hardware User Guide”).
Note: last <urcmode> settings are saved as extended profile parameters.
Note: GPIO is set to LOW when antenna is connected. Set to HIGH otherwise
Note: #GSMAD parameters, excluding <urcmode>, are saved in NVM.
AT#GSMAD=?
Test command reports the supported range of values for parameters <mod>,
<urcmode>, <interval>, <detGPIO> and <repGPIO>.
AT#GSMAD?
Read command returns the current parameter settings for #GSMAD command in
the format:
#GSMAD: <mod>,<urcmode>,<interval>,<detGPIO>,<repGPIO>
