GSP-1720 SDVM AT Commands

leave a comment »

In addition to the AT commands that are defined in the SDM Integrators’ Manual, the SDVM supports the following commands:

AT&Wn               User is allowed to save the current snapshot of parameter commands into two profiles (1 and 2).  It is an error to save to profile-0 which contains the factory defaults.

Where:
n=1 (AT&W1) will save current AT parameters to user profile #1
n=2 (AT&W2) will save current AT parameters to user profile #2

ATZn

Where:
n=0 (ATZ or ATZ0) will reset the AT table to factory default
n=1 (ATZ1) will reset the table to the user saved profile #1
n=2 (ATZ2) will reset the table to the user saved profile #2

AT+VTS           Sends a single DTMF tone: 0-9, * or #.  The UT must be in a call for this command to work.

AT$QCHFn     where “n” is either 0 or 1.  Sets the audio path to HFK (AT$QCHF0) or house kit (AT$QCHF1). Currently this command has not been tested as there is no HFK to test against.

AT+CDV=<phone number>   Dial a voice call

AT+CHV         Hang up voice call

AT$QCCAV    Answer incoming voice call

AT$QCDMI=<pref> USB port configuration

Where:
<pref> == 0 : Both DM and Data (requires QC composite driver)
<pref> == 1 : Data only
<pref> == 2 : DM only

AT$QCCTL=<pref> Auxiliary port configuration

Where:
<pref> == 0 : none
<pref> == 1 : control port
<pref> == 2 : nmea port
