I'd need some help with the writing of an XML file for an experiment in which two arduino send accelerometer data to the phyphox app.
I am completely new to XML languange so any hel will be appreciated.
I am using the experiment editor of phyphox. I'll try to explain what I've done and what I am missing.
-In the Main window of the editor I've just added the title of the experiment
-In the input window I've added two bluetooth modules.
Identification: set to right and left, respectively. I'll move the sensors with my right and left hands
Device names: right_ARD and left_ARD. I will set the same device names when uploading the codes on the two sensors.
Service UUID: I've left this blank. To connect the sensors to the app is it sufficient the Device Name or do I need this information as well?
Mode: Poll. I need the sensors to send data continuously at a sampling rate of 100 Hz (which I put in the following box). is the correct?
I've checked the Subscribe on start boce as i want to start the experiment manually from the app
Config: I cannot understand if I have to change something in this case
Output: From what I understood I should add three outputs, one for each axis of the accelerometer. After this I don't know what should I do. Which of these boxes are mandatory to be filled? I can imagine that as Conversion function I should use some from the Float option as it is the format of the variables that I will use to read the accelerometer data on the arduino (as in the random number experiment for BLE). In the characteristic boxes shoul I put the name of the variables that I will use on the arduino code to store the data?
-I didn't consider the Output window as i don't need the app to send data to the sensors
-Views
I've added two views with three graphs each, one for each component of the accelerometer data.
I've just change some labels of the graphs and the x y axes
-Analysis
I've just created empty buffers and connected them to the graphs.
This is what I managed to do.
I'll post the code here
What are you using on the Arduino side: phyphoxBLE? I would likely use our library for both microcontrollers and merge the two generated experiments into one by a text editor.
On first sight, both BLE characteristics write into the same buffer, accordingly you have two identical graphs. I assume that is not intended…
Answers to some of your questions:
the UUID is (mainly) a generic identifier for heart rate monitors, HID services etc.,
“notification” mode lets the microcontroller set the rate, we mainly use this ourselves,
phyphox does not record data before tapping start, so likely no subscribeOnStart required
conversion indicates to phyphox how the data is transmitted, float or integer requires the lowest amount of data (again: phyphoxBLE would take care of that and you could look into the generated experiment)

I've even tried to upload the original CreateExperiment skech but it gives me the same error
I'm stuck here for now.
could you share some more informatione about your current setup? Which microcontroller and software versions (board firmware, library version) are you using? Unfortunately I cannot reproduce this issue.
Thank you to both of you.
I am using an Arduino NANO 33 IoT, with dirvers version 1.4.3.0 on Arduino IDE 2.2.1. The phyphoxBLE library I used was 1.2.0.
Anyway. I tried to installe the 1.1.2 version of the library and I tried to upload the Createexperiment sketch as is.
It is compiling and uploading the sketch but when I try to connect the device to the app it just start loading the experiment but then do nothing.
After this I tried to search again for the device and the app didn't find it.
Just once I got this error message on the app:
"it is not possible to abilitate the notification of the Bluetooth Characteristic with UUID cddf0002-30f7-4671-8b43-5e40ba53514a."
Now if I try to upload the sketch again or any other sketch on the board the Arduino IDE compiles the sketch but then doesn't upload it without giving any error.

Compilation error: exit status 1
I've even tried to upload the original CreateExperiment skech but it gives me the same error
I'm stuck here for now.
Dominik could fix this bug that is surprisingly not triggered on other boards. We should do a bit of testing before we release it.
