5.4.4
This sentence sets the pulse-per-second (PPS) output on or off. This is a set-only sentence.
$PXEMaPS,x*hh
Example:
$PXEMSPS,1*6E
$PXEMRPS,a*6E
5.4.5
This sentence configures the application serial port communication parameters.
$PXEMaPT,xxxxxx,x,a,x*hh
Example:
$PXEMSPT,009600,8,N,1*6E
$PXEMRPT,a*6E
5.4.6
This sentence forces the receiver to perform a software reset. It also allows starting up and shutting down the FirstGPS
library without performing a full software reset. This is a set-only sentence.
$PXEMaRT,a*hh
Example:
$PXEMSRT,W*6E
$PXEMRRT,a*6E
