I am trying to send data from a sensor connected to Arduino UNO to MATLAB for analyses. I downloaded and installed the Arduino Support Package and Instrument Control Package. I run "arduinosetup()" in MATLAB and follow the steps. I get to the step "Configure Bluetooth Device" and the drop down box of "Choose Serial Port" option only has the COM port of the Arduino Board. When I select that I get an error "Failed to configure the Bluetooth Device. Check the serial port and your device wiring" I know the problem is not the wiring because I have checked multiple times and it is only 4 wires. How can i get the correct COM port to be an option in the drop down box?
