Momentary GPS data dropouts with PowerFLARM to SN10A to Oudie2 setup

Should be fixed in SN10 v2.38, expected release after
18-meter nationals. Contact me offline to help with Beta.
Thanks,
Best Regards, Dave "YO electric"

Hi Kirk,

If the new SN10 software doesn't fix the problem. On the Oudie, go to Menu
Settings Input and change the "Last Sentence". Use trial and error to
find a sentence that works the best.

May be able to help you with this one as I've had the same problem since
getting my new Oudie 2 last Summer and it has driven me nuts but I've
recently solved the issue with help from Andrej.

Go to SettingsHardware and uncheck GPS forwarding(it's an LNav only
thing), and more importantly uncheck Use backup GPS.

My theory is that if you are using an external GPS input on Comm 4 as
Primary with Backup GPS checked, then every time the Oudie senses that the
Primary GPS is on the threshold of useability it switches to backup and
then it can't make it's mind up which to use and you end up with the
continuous and very annoying switching back and forth between the two -
there's a conflict in there somewhere.

Yes you lose the back up GPS feature but do you really need it? - my set up
has been rock solid for weeks now when before I had the problem EVERY
flight.

Good suggestion - I'll try that in case the SN10 bug fix doesn't work.

Thanks!

I think I can help you with this one as I've had the same problem myself
and it's driven me nuts but it's now sorted with help from Andrej.

I bet you're using an external GPS on Comm 4 and have Use backup GPS
checked in HardwareSettings?

You must UNCHECK Use backup GPS and while you're there uncheck Use GPS
forwarding which is an LNav only thing.

There's a conflict in there somewhere that causes the backup GPS to kick in
every time it sees the slightest degradation of Primary GPS signal, even if
it's only momentary, so it then cannot make it's mind up which to use and
you end up with this continuous and very annoying bouncing backwards and
forwards between the two. If your using a good primary GPS input you don't
need the backup facility anyway.

I've now had several weeks of trouble free operation after suffering this
problem on almost every flight.

Why are you running the V7 oudie combo at 4800 Baud.

Configure the Garmin as fast as it will go but less than the Oudie.
Set the Oudie as fast as possible at least 115,200.

Make sure use backup GPS and GPS Forwardign is unchecked.
