Hello all,

I would like to read in data from a Bluetooth Device through my Bluetooth Adapter. I've tried to use the serial('COM1') and fopen/fread commands, but I do not receive any information. I've made a COM or Bluetooth connection through Windows' Bluetooth Devices and used the same COM ports to read data. I've also tried leaving this Windows' connection out and going through all the available COM ports to see if I can receive anything.

I have not found much information on using a Bluetooth Adapter and reading data from a Bluetooth Device.

Greetings,

Hans

Is your bluetooth adapter a bluetooth to serial adapter?

No, it is an USB Bluetooth dongle, I would like to use this dongle in order to send and receive data.

As mentioned above, direct bluetooth communication does not work. However, if your bluetooth supports Serial Profile (SPP) that enables the bluetooth to show up as a serial port (COM) then you should most probably be able to talk to it.

It is most probably a case of setting the correct properties for the serial object in MATLAB. Check BaudRates, FlowControl, Terminator etc.

A simple test would be to try and talk to the bluetooth device from hyperterminal. Note those settings and just replicate them in MATLAB.

A quick search on File Exchange gave some hits that you could look for reference!
