Releases, Documentation ??

Post by Patman » Mon Feb 08, 2016 5:29 am

Hello!

I am new to openXsensor. Till v2.5 I can find some releases for download (https://github.com/openXsensor/openXsen ... _Downloads).
In the news I can find that a version 7 is available.

Where can I download the releases? Is the master always the stable and latest release?

Regards,
Patrick

Master is normally the latest stable release.
Some time when I plan to make quite big changes I create a new branch and I add the new functionalities in this new branch. When I expect that this new branch is OK, I merge it to master and I usally remove the other branch. At this time, it could be that there are still some bugs in the master branch because I can't test all functionalities.

Currently, I did not created a release for version 7 because I am still making minor changes based on the feedbacks and requests I get.
You can easily download it from the home screen
https://github.com/openXsensor/openXsensor
Select the master branch (left in the menu bar) and then click on "Download Zip" (right in the menu bar).
There is a file named version.oxs that contains the version number.
Still this version number does not reflect all minor changes. I upgrade the number only when there are significant changes.

Hi,
yesterday I built an openXsensor with GPS.
Altitude, VSPD, and VFAs are o.k.
Gps Lon, Lat also o.k.
Galt shows either about 30m or jumps to about -30m. The real height is about 155m.
Other GPS values are not shown.
I use a Taranis Plus FW 2.17 with a D-receiver
I have tried two different Ublox Neo6M (9600 baud 1Hz)
The results were absolutely identical.
I tried to fault finding but unfortunately are not my skills enough.
Are there any new insights already?

Are you using the latest version in master branch?
I just checked the code and it seems OK for GPSAlt. Still I did not test it.
Another member is currently making tests (also with a D receiver) and he did not report an error about this. Still he is using openTx 2.0 (instead of 2.1)

I now flashed the 5 hours old FW.
Galt is still about 29 m (-29 m), but now Hdg appears.
Despite km h setting in config.h, kts displayed.

I just made a minor change for GpsAlt. The new version is on github.
Still, I am not sure that it will solve the issue.
Can you test it?

About km/h, this setup in oXs is discarded for Hub protocol because this protocol expects that the GPS speed is in knot/h.
I think that openTx converts it to km/h if you ask for (using metric units in your setup).
Still, as far I remember, this conversion by openTx occurs only for the values being displayed on the screen and not for the log.

So I expect it is now OK (other member also said me that it seems ok)

Thanks for you help fixing it.

After I did some experiments with the OpenXsensor-GPS and my antennas Tracker today, I noticed that SAT's and Fix is not displayed.
Did I do something wrong?

Number of sat and type of fix are transmitted only in Hott (Graupner) protocol.
I think that other protocols do not have telemetry fields to transmit those data.

Note: as far I remember, GPS data are transmitted only when there is a 3D fix

In order to assess the quality of the GPS signal, it may be important to indicate the number of the satellite.
Somewhere that was taken over Tmp1 or Tmp2.
e.g. See 8 satellites and Fix 3 for "83".
It can be seen earlier if everything is in order.
That was here: https://github.com/SamuelBrucksch/diy-frsky-gps
