Then create somewhere a file called +"irda", "bluetooth" or "tty" to connect to the device using IrDA, Bluetooth or +TTY transport. + +For the "bluetooth" put there a line "CP:AD:RE:SS channel", where CP:AD:RE:SS +is the hardware address of the device you want to connect to, and channel is +the OBEX File Transfer channel; you can discover the address and the channel +for your device by using commands like "hcitool scan" and "sdptool browse". +Other lines in the file are ignored. + +Put a device name like /dev/rfcomm0 into the "tty" file. + +The content for the "irda" file is ignored. + +Now run this "cd" command in the Midnight Commander (in the "bindings" files +the command is "%cd"): cd bluetooth#obexftp.
