Re: error message while compiling for arduino mikro (leonardo)
oXs needs an AVR328p processor. It is used on Uno, nano, pro mini but not on leonardo.

Re: openxsensor causes sensor lost
Perhaps, the 2 sensors share the same device ID. You can try changing the device ID from oXs Gps. It is in file oXs_config_advanced.h It is defined in line #define DATA_ID_GPS 0x83 // 3 used for GPS data You can try using an other values than 0X83 but the value must be in the list below: //list of 2...

They are I2C so in theory it could but it is currently not supported by oXs ( and there is no real interest).

Re: 6S with Temperature
Measuring the total voltage of a 6S should not be an issue at all. Measuring the voltage of each cell will probably be less accurate on the last cells because the cell voltage is calculated based on the difference of e.g. 5th and 6th cells. So a small error on a value can give a bigger error (in %) ...

Re: graupner mx16 hott
You still have

I do not know if this is what you wanted (not needed for vario + gps sensor).
Anyway, this should not be the reason fot not getting data on the Tx

Re: 6S with Temperature
Please note that the voltages of the 6th cell will perhaps not be very accurate because it will be calculated substracting total 5 cells voltage from total 6 cells voltage. A small error on total 5 cells voltage and on 6 cells voltage will have a much greater impact on the difference. In order to ge...

Re: openxsensor with BMP280
The BMP280 is connected to the arduino using I2C bus. It means it uses: - SDA = pin A4 on arduino - SCL = pin A5 on arduino. Note: I expect BMP280 SDA and SCL are 3.3V signal. So, if you use a 5V arduino, to fe safe, you have to use a bmp280 module that has level converters. Arduino is connected to ...

Re: New beta version of openXsensor (=openXvario)
When you try the vario, did you also connected a baro sensor (MS5611, BMP...) to the arduino. Compiling declaring a baro in the config but without having a baro sensor connected just blocks the arduino because it is waiting for data on the i2c bus. This is not the case for the flow sensor because it...

Re: OpenXSensor HoTT Temperature
There is probably a bad soldering somewhere.
If you make the folowing connection
5V <-- 100K resistor --> A0 <-- Probe --> Gnd,
The voltage on A0 should be 5V * (Probe resistance ) / (Probe resistance + 100K)
So at 18.5 °c it should be 5V * 2.2 /3.2 = about 3.8V

Re: OpenXSensor HoTT Temperature
Do you have an Ohmmeter?
If yes, then mesures the resistance of the probe when it is not connected.
I would expect that at 25°C, the resistance should be about 100K.
Do you have the reference (or a link to the site where you purchase it) of your probe?
