TC third, I don’t understand where you got these commands from…you should strictly refer to the manual: Resources - SparkFun LG290P Quadband GNSS RTK Breakout Hookup Guide
However, I thought it would be better to set the breakout as the base and the postcard as the rover.I tested the breakout at 57K (errata corrige) baud but you have to use MSM7 & ephemerides.
Using the protocol the commands to set the base are these in order
For the postcard just reset it and it is already ready.
base_mode for breakout:
$PQTMRESTOREPAR*13 Clear all data to default
$PQTMGNSSSTOP*09
$PQTMCFGRCVRMODE,W,2*29 # set receiver to base mode
Set the base in ecef --> $PQTMCFGSVIN,W,2,0,0,x,y,z*<Checksum> <-- need to compile and run the checksum
$PQTMCFGSVIN,R*26 check if ecef base is correct (U can ask in postcard sending the above command and copy the coord)
$PQTMCFGRTCM,W,7,0,15,07,06,2,30*36
$PQTMSAVEPAR*5A
$PQTMSRR*4B
$PQTMGNSSSTOP*09
$PQTMCFGMSGRATE,W,1,3,RTCM3-1019,1*56
$PQTMCFGMSGRATE,W,1,3,RTCM3-1020,1*5C
$PQTMCFGMSGRATE,W,1,3,RTCM3-1041,1*5B
$PQTMCFGMSGRATE,W,1,3,RTCM3-1042,1*58
$PQTMCFGMSGRATE,W,1,3,RTCM3-1044,1*5E
$PQTMCFGMSGRATE,W,1,3,RTCM3-1046,1*5C
$PQTMSAVEPAR*5A
$PQTMSRR*4B
$PQTMCFGMSGRATE,W,1,3,RTCM3-1033,0*5F
$PQTMCFGUART,W,3,57600*34
$PQTMSAVEPAR*5A
$PQTMSRR*4B
Anyway if U would try on the postcard first, set as follows for the base mode
not rover…
$PQTMCFGRTCM,W,7,0,15,07,06,2,30*36
$PQTMSAVEPAR*5A
$PQTMSRR*4B
$PQTMGNSSSTOP*09
$PQTMCFGMSGRATE,W,1,3,RTCM3-1019,1*56
$PQTMCFGMSGRATE,W,1,3,RTCM3-1020,1*5C
$PQTMCFGMSGRATE,W,1,3,RTCM3-1041,1*5B
$PQTMCFGMSGRATE,W,1,3,RTCM3-1042,1*58
$PQTMCFGMSGRATE,W,1,3,RTCM3-1044,1*5E
$PQTMCFGMSGRATE,W,1,3,RTCM3-1046,1*5C
$PQTMSAVEPAR*5A
$PQTMSRR*4B
$PQTMCFGMSGRATE,W,1,3,RTCM3-1033,0*5F
$PQTMSAVEPAR*5A
$PQTMSRR*4B
as you notice, you have to save and reset several times
