hi,
the old version(air530) works great, i use only RMC with 10hz output/position update.

But the newer version(air530z) works only at about 5hz position update.
with less then 10 satellites the position update is at about 10hz, but it drops with more satellites in sight.

what can i do?

what did you send to the GPS to enable 10hz?

interested in this as well.

I use these commands:


  Serial1.println("$PMTK220,200*2C");  // Set update rate to 5Hz using PMTK
  Serial1.println("$PCAS02,200*2E");  // Set update rate to 5Hz using PCAS

but it doesn’t change anything, still on 1Hz

NMEA update 10Hz:
on air530: "$PGKC101,100*32"
on air530z: "$PCAS02,100*1E"

are you 100% sure it’s PCAS for the Air530Z? Because then, my 2nd line

.println("$PCAS02,200*2E");

would be correct for 5Hz, but it doesn’t change anything

you can try both, maybe you have just a air530?
or sometimes the println() function doesnt work, try write().

I see the label “530Z” on it :slight_smile:

Maybe my baud-settings are wrong, though receiving works fine?
