Re: Exchanging data over Bluetooth Classic

Hi,

you can use L2CAP or RFCOMM sockets to transfer data. Or you can use
OBEX as provided by obexd if it is more file related transfer you are
after.

Thanks for the reply. What is the most convenient way to programatically
use L2CAP or RFCOMM? There is one guide [1], but I reckon it's out of date since Bluez made the transition to DBUS. I heard it's possible to create
a character device for RFCOMM sockets; using them programatically them
reduces to the usual open/read/write/close of a file descriptor. Is this
still possible? (Mind you, Bluez docs are laconic in the extreme!)

Best regards,
Dario Teixeira
