Re: OpenXsensor and Frsky SxR Receivers

I expect that there is another reason for the issue because oXs uses by default the following device Id's #define DATA_ID_VARIO 0x00 // = sensor 0 used for Alt and Vspeed #define DATA_ID_FLVSS 0xA1 // 1 used for Cell values #define DATA_ID_FAS 0x22 // 2 used for vfas , current and fuel #define DATA_...

Re: OpenXsensor and Frsky SxR Receivers

I have no experience with S8R but perhaps there is an incompatibility in the device ID being used.
oXs uses several devices ID's depending on the sensors being defined.
It is possible to change the devices ID's being used by oXs if this is would be the reason.

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...

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: 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

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?
