I am posting this one first. I will post all three separately, to reduce potential for confusion (on my part as well as for the reader).
You could also try the #define DEBUG thing with the NOT working baro + GPS oXs yourself.
.........................
I have no knowledge of how to start with that. I figure it will be better to wait for further information about that before (probably) compounding the problem and increasing resulting confusion/mis communication etc.

Supplementary information (may or may not be relevant):

Taranis X9D Plus on OpenTx version 2.2.3
Companion version: 2.2.3
Baro BN-180
Computer operating system: Linux Mint 19.3
Arduino IDE version: 1.8.12
Barometer reading at time of testing: 1009 kp.
Atmospheric temperature 18 deg. C
Google Earth coords for same location as test above: 30.24 S 152.56 E to the nearest minute.
Arduino nano clone board used. (ex Banggood).
Proper old fashioned lead solder used throught!

I sincerely hope I have provided sufficient information.
Please let me know if I have not.

I will do the BMP280 Vario only test tomorrow.

Jim.

Karl,
Please read my post above.
I have quoted your words, exactly as you asked. The quote at the top of my post clearly indicated: "working GPS oXs".
Picture of the displayed coords attached.

Please find picture attached of my working GPS.
I forgot to attach it to the post above. I have edited the post to include it.

I will do the Vario / BMP280 openXsensor test tomorrow and take a video of it working.

Karl,
Please note: this is a Working Vario.
I am using the same board, same sketch as the previous working GPS test. It's working, but not very sensitive. I am ordering a MS5611 to use instead of this BMP280 baro.

Success!

Post by Endorphin » Mon May 25, 2020 1:48 am

I now have both functions working on the same arduino nano board.
BN180 GPS and BMP280 baro Variometer.
Same sketch as I have been trying for weeks now, before this, without success.
The only thing I have done differently is to power the GPS sensor off 3.3 volts and not 5 volts, as previously.

Wow!
This has been a long haul.
Thanks to all, especially Karl.

Jim.
