Hello Claudio,

I understand your comment.

But, I am trying to use the serial service and I do not understand one point :
after a ConnectService, the only way to disconnect it (disconnect rfcomm and acl), is by closing connection from remote side.

   ~ # dbus-send --system --type=method_call --print-reply --dest=:1.19 /org/bluez/serial org.bluez.serial.Manager.ConnectService string:00:01:02:03:05:06 
string:spp
   serial[1048]: /org/bluez/serial: org.bluez.serial.Manager.ConnectService()
   serial[1048]: Connect in progress
   serial[1048]: rfcomm_connect_cb: connected
   serial[1048]: name_listener_add(:1.28)
   method return sender=:1.19 -> dest=:1.28
      string "/dev/rfcomm0"
   serial[1048]: Connect requestor :1.28 exited. Releasing /dev/rfcomm0 node
   ~ # dbus-send --system --type=method_call --print-reply --dest=:1.19 /org/bluez/serial org.bluez.serial.Manager.DisconnectService string:/dev/rfcomm0
   serial[1048]: /org/bluez/serial: org.bluez.serial.Manager.DisconnectService()
   Error org.bluez.serial.Error.DoesNotExist: Invalid node
     // Here, the RFComm connection is still up until remote side disconnect

How can I disconnect rfcomm (and acl) connection from local side (currently, the serial service has opened a file descriptor on /dev/rfcommX, that is close only 
on remote disconnection, keeping up the /dev/rfcommX device) ?

What I want to do in my program is : ConnectService, open rfcomm, DisconnectService, than use file descriptor on rfcomm. Close rfcomm after, that should 
disconnect the bluetooth connection.

Hope I am clear

Regards

Fred
