$PSTMSBASSTART
Initialize and start all SBAS routines. The SBAS software has been included in this ROM image but has been disabled by default.
For this reason at each system reset the SBAS activity will be OFF and needs the $PSTMSBASSTART command to start.
Command: $PSTMSBASSTART<cr><lf>
Results: The SBAS version string will be sent as reply.
$PSTMSBASONOFF
Suspend / resume the SBAS software execution. When the SBAS is running (after a $PSTMSBASSTART command) it can be
suspended and resumed using the $PSTMSBASONOFF command.
Command: $PSTMSBASONOFF<cr><lf>
Results: If SBAS was running it will be suspended, if it was suspended it will start to run.
$PSTMSBASSAT
Change the SBAS satellite.
Command:$PSTMSBASSAT,<prn><cr><lf>
Results: If the SBAS satellite is available in the above range, the software starts tracking. If the parameter is zero, the system
automatically searches for the SBAS satellite available in the user region.
$PSTMGETSWVER
Get the version string of the GPS library embedded in the ROM code.
Command: $PSTMGETSWVER <cr><lf>
Results: The version string will be sent out. As example: $PSTMVER,GPSLIB_04.30.03+PAL ARM-Jul 28 2006 12:23:26
$PSTMFDAONOFF
Toggles the Fault Detection Algorithm ON/OFF. The FDA can be used to overcome drift due to interference.
Command: $PSTMFDAONOFF<cr><lf>
Results: If the FDA was enabled it will be disabled. If the FDA was disabled it will be enabled. On power-up the default mode
is OFF. After each power cycle the FDA must be toggled back to the ON state.
$PSTMLPON
Put the CPU speed at 16MHz. This command is available starting with ROM version 4.30.3.
Command: $PSTMLPON<cr><lf>
Results: The CPU speed will change to 16MHz. NOTE: this command could be useful to reduce dynamically the power
consumption, when the CPU load is not critical.
$PSTMLPOFF
Put the CPU speed at 32MHz. This command is available starting with ROM version 4.30.3.
Command: $PSTMLPOFF<cr><lf>
Results: The CPU speed will change to 32MHz. NOTE: this command could be useful to restore the standard CPU frequency at
the end of a low power period.
$PSTM2DFIXONOFF
Enable/Disable the 2D Fix algorithm. This command is available starting with ROM version 4.30.3.
Command: $PSTM2DFIXONOFF<status><cr><lf>
Results: According with the input parameter the 2D fix algorithm will be enabled or disabled.
NOTE: to see the effects on the TTFF the GPS engine should be reset using the $PSTMGPSRESET command.
