How to monitor and control arduino based drone through matlab ?

Hi,

I am trying to build a student project with a drone using arduino nano IOT/BLE and matlab. The goal is that the drone should be able to send data from the IMU to matlab with the latter performing a PID action to control the drone. Ideally , all IMU variables can be monitored and controlled online by matlab or simulink.

The problem so far :

• I can connect the Nano Iot or BLE using an USB cable for setting up a wifi or bluetooth connection via arduinosetup, but after unplugging the cable , re-connecting to the arduino is impossible using just a powered usb. On the menu of the arduino configuration in matlab, the port (COM4) does not show up anymore. I have followed some guidelines (also question was raised in the forum) but the problem persists. I am guessing that if the USB is unplugged, the matlab server code is erased from the arduino but then I don't see the point of it.

I am actually not sure this is the right way to do it. Are there tutorials for this kind of project or is it not possible ?

Any help would be appreciated !

Cheers

See https://www.mathworks.com/matlabcentral/answers/2174257-connect-arduino-to-matlab-through-bluetooth#question_2174257 that says that MATLAB can't but SIMULINK can.

So once programmed, simulink allows to access variables from the program even if the arduino is not connected anymore by usb?

I know nothing about Simulink, sorry...just looking at what I could find that might be pertinent to your query...

arduino from the R2025b doc.has <link to supported hardware with capabilities table>

Arduino Nano IoT and BLE are both supported for BLE. I can connect to them this is not the problem.
