Hi everyone,

I am trying to connect an Arduino Nano BLE 33 to my PC through MATLAB. I am using Win11 on my PC, and I actually do not know how Arduino is programmed (but it is a minor problem for now).

I just need to make sure that I can connect the device to Matlab, and I went through BLE Matlab documentation.

Firstly, I have checked my device is present and running blelist function I got some available devices and mine too:

 Index           Name              Address        RSSI    Advertisement
    _____    __________________    ______________    ____    _____________
      1      "LE_WH-CH700N"        "38184CD24082"    -55      1×1 struct  
      2      "SC-Device"           "0456142755E8"    -65      1×1 struct  
      3      ""                    "7FB73C7AA99D"    -68      1×1 struct   

I am interested in second position device: SC-Device.

To the point I need I went to run ble function as follows:

bt = ble("0456142755E8")

I expected to create a Bluetooth Object which can handle some basic functions to write and read data. When I run ble function (as cited above), Matlab keeps stopping for long time as long as I forced closing the window. Using ctrl+c to interrupt the process I did not get any feedbacks, and Matlab keeps Busy status.

Does anyone know why I get this behaviour?

Thanks for your support, it would be really appreciated.

Best,

V
