Bluetooth Connection Error to Arduino Nano 33 BLE Sense

I have properly programmed my Arduino Nano 33 BLE Sense for Bluetooth connection using the arduinosetup command with the Arduino connected via COM port. The test connection fails after programming, but the board still shows up when I use blelist and checking for available devices on my labtop. I made sure I have windows 10 and am attempting to use a=arduino("the board address") to connect.

The newer versions of MATLAB have an error. Use version 2021b and you should be able to connect to board over Bluetooth.

Hi Stephen, since you're experiencing issues with the test connection, here are some steps that you can follow to troubleshoot the problem:

1. Make sure that you have the MATLAB Support Package for Arduino Hardware installed. If not, you can download it from the MATLAB Add-Ons page.
2. In the "Arduino" window, click "Add Board" and select "Arduino Nano 33 BLE" from the list.
3. Once the correct port is selected, click "Test Connection" to verify that the Arduino is properly connected.

Test with a different device: If you're still unable to connect to your Arduino Nano 33 BLE Sense, try connecting to it from a different device. This will help you determine if the issue is with the device or with your laptop.

After strenuous testing, there is a bug in the newer versions of MATLAB to connect to this device. For anyone trying to use the Arduino Nano 33 BLE Sense over Bluetooth, use the 2021b version of MATLAB as the bug is not present here.

Is this still a problem in Matlab 2025 versions ? I am experiencing similar problem with Nano 33 IoT
