Failing to open serial port

I have an Audrino connected via Bluetooth to my PC. I use a BT dongle and the Aurduino device is found to be in COM6. When I try to open this port as follows:

s = serial('COM6') fopen(s)

This is what I get:

Error using serial/fopen (line 72) Open failed: Port: COM6 is not available. Available ports: COM1, COM6. Use INSTRFIND to determine if other instrument objects are connected to the requested device.

How can COM6 be available and not available at the same time...?

Thanks

Try using instrfind to get the serial ports and pass the appropriate result from instrfind to fopen -- just in case there is some small invisible oddity in the string.

how can u explain

delete(instrfind('type','serial'))

and then try the serial() again.
