T1 , VOLT1 , 1 , 1 , 0
With T1 show both receivers 125 instead of 12.5
If I use: T1 , VOLT1 , 1 , 10 , 0
The display is 12 instead of 12.5
But the speech is "degree" instead of volts!
The telemetry settings on the Taranis are identical for both receivers!

Unfortunately I only have little knowledge of programming in Basic.
My thought:
If OXS recognizes a Sport receiver, then
#define SETUP_DATA_TO_SEND \

Vfas, VOLT1, 10, 1, 0
otherwise
Vfas, VOLT1, 1, 1, 0

would that be a possibility?

OK.
running with one firmware!

oXs vario for FrSky (works also with MPX) with BMP180 sensor for 3,50 Euro.

Nice work. :) Is it as accurate as the other more expensive sensor?

Thanks

João

P.S. - Watched your youtube video and didn't know the taranis could read the news..... in German.. It's a hell of a radio :mrgreen: Can it also do it in Portuguese?? :mrgreen:

Hi João.

No, I don't think, it is as accurate as the MS5611. Klaus (see the rcline thread) did the modification of oXs ver.3.0 for support of the BMP180 and he did not post his experience so far. I am now the second one with oXs + BMP180.

br KH

... and it is DEUTSCHLANDFUNK, not the Taranis. I did not realize, that there was sound recording :mrgreen:

How much worse is the bmp180 compared to the 5611?
My main purpose is vario tones, I have the frsky normal precision vario and don't find it a lot of use apart from in a dlg for launch height , the high precision and ms5611 openxsensor is much more useful as vario.
Where can I find the code with the bmp180 code in?
For less then £1 I might just get one and try it myself, any input welcomed.
Thanks.

You find it here. It is version 4.0 (FrSky and MPX protocol. MS5611 and BMP180 sensor)

Thanks, I will order one just out of interest, I already have more varios then receivers lol but 85 pence for a sensor and I already have q spare pro mini I can do a comparison if nothing else , I wonder if using it as a second sensor as total energy sensor along with my ms 5611 varios would work?

In order to build build a pneumatically total energy sensor with you need only one baro sensor. It could be a MS5611 or a BMP180.
You can use 2 baro sensors if you want to get the altitude or an uncompensated vertical speed too.

For an electronically total energy sensor you need a baro sensor + an airspeed sensor (at least with oXs).

Thanks, so which is easiest , basically I want altitude and vario tones like I have but the vario tones not be effected by me pulling the nose up and giving false lift tones.

In order to get a compensated vario (providing dte), you have 2 basic options:
- pneumatically compensated vario: use one MS5611 sensor and connect it to a TEK probe. More info on TELK probe on this link : viewtopic.php?f=86&t=5856&p=83775&hilit=TEK#p83775
Pro: cheaper (if you build the probe your self)
Con : TEK probe needs some calibration for optimal result.

- electronically compensated vario : use a MS5611 sensor and an airspeed sensor + a Prandtl probe.
Pro : normally no calibration needed
Prandl probe available on the web.
Con : price of the airspeed sensor
Prandl probe is perhaps not so easy to build (I made one using 2 part of an old 35mHz antenna)

Some other users (Carbo?) can perhaps share their experience here.

Two additional remarks:

With a Prandl probe you have the airspeed-value to optimize your plane in different flight-modes.

The TEK-Probe fits for me better in V-tail planes (mounted in the fuselage in front of the wing), on T-tail planes i prefer a Prandl-probe, mounted in the vertical fin. The vario-compensation and the flyability is exactly the same in both versions.
