Hi,
I’m a student and for the school project we bought LC79H and we want to communicate using I2C with the µc.
Is there any I2C bus frame to get only $GNRMC data (date and time) ?
Does Arduino example code exist ?
Thanks
Maël
Yes, if already connected and working in I2C
Just disable messages with 0
$PAIR062,0,0*3F # turn on GGA messages (0
$PAIR062,0,1*3E # turn off GGA messages (0
$PAIR062,1,0*3F # turn off GLL messages (1
$PAIR062,2,0*3C # turn off GSA messages (2
$PAIR062,3,0*3D # turn off GSV messages (3
$PAIR062,5,0*3B # turn off VTG messages (5
$PAIR062,6,0*38 #Turn off ZDA messages (6
$PAIR062,7,0*39 #Turn off GRS messages (7
$PAIR062,8,0*36 #Turn off GST messages (8
$PAIR063,-1*0F ask if done: see pos. after -1 ((e.g.in lc29h_series $PAIR063,-1,1,0,0,0,1,0*0F))

But your module should also have $GNZDA,who spits
only Time & Date
If need only time and date and not $GNRMC
$PAIR062,4,0*3A #Turn off RMC messages (4
$PAIR062,6,1*39 #Turn on ZDA messages (6
then save with
$PQTMSAVEPAR*5A # save PQTM params to flash
$PAIR023*3B reboot module

P.S see mistake in first rows…turn off instead of on and viceversa.
System let not modify anymore after few seconds!!!
