Here the current project status:
I first worked on the xml files to make sure that I understand the concept correctly and get everthing implemented.
For this I combined the Acceleration, GPS and Gyro Sensors in one experiment.
The XML file looks like this and works fine:
I then tired to connect the ESP32 C3 via BLE not over the BLE button in the app but over a selfemade project in the project editor.
I tried 2 tutorials to set up the arduino, but could not get it running.
Bluetooth | Seeed Studio Wiki
ESP32 BLE Server and Client (Bluetooth Low Energy) | Random Nerd Tutorials
With the first tutorial I was able to change the Device name of the ESP32.
With the second one I was able to generate some input to the App but not my sensor readings.
The code after the first tutorial looked like this:
And after the second tutorial it looked like this:
The xml file for the second tutorial looks like this:
I guess my problem after the second tutorial is that I send the wrong values (or format?!) to the phyphox app.
But I am not sure what to change tbh.

<description>Get raw data from the accelerometer and GPS. This sensor will not subtract the gravitational force, so it will report an acceleration of 9.81 m/s² even when the phone is resting.</description>

</phyphox>I then tired to connect the ESP32 C3 via BLE not over the BLE button in the app but over a selfemade project in the project editor.
I tried 2 tutorials to set up the arduino, but could not get it running.
Bluetooth | Seeed Studio Wiki
ESP32 BLE Server and Client (Bluetooth Low Energy) | Random Nerd Tutorials
With the first tutorial I was able to change the Device name of the ESP32.
With the second one I was able to generate some input to the App but not my sensor readings.
The code after the first tutorial looked like this:
Code:

</phyphox>I guess my problem after the second tutorial is that I send the wrong values (or format?!) to the phyphox app.
But I am not sure what to change tbh.
