MATLAB serial communication via Bluetooth SPP. Learn more about bluetooth, spp, serial port, java, serial Instrument Control Toolbox. Bluetooth Communication. I've made a COM or Bluetooth connection. Loic Low Orbit Ion Cannon 1.1.1.14. It is most probably a case of setting the correct properties for the serial object in MATLAB.

I have some sensors with Bluetooth SPP connections. I cannot seem to get MATLAB Serial IO to work with them. The 'Standard Serial over Bluetooth link' COM port entries are available in Device Manager, the port settings (in Device Manager and the MATLAB serial function call) are correct.

On using fopen() the error seen is that the requested com port is not available. This is confirmed using instrhwinfo('serial') as the requested COM port is not in the list. I know the Bluetooth SPP is working because the only way I could get the devices working with MATLAB was to use a third party com2tcp forwarder, then use MATLAB's tcpip function to access the port. However, this is not ideal since the com2tcp forwarder is not that reliable. I'd rather be using MATLAB's serial io. Could this be an issue with the java version being used? Version('-java') gives 'Java 1.6.0_24-b07 with Sun Microsystems Inc.
