El Demonio Negro

Estas son algunas notas recopiladas y que puede que carezcan de sentido (aunque de por si a muchos ya se lo parecerá ;)) de cuando intenté conectar por bluetooth mi teléfono móvil modemo nokia 6230 a una Debian. Llegó a funcionar, pero pasado un tiempo sin usarlo dejó de funcionar. Probé el mismo procedimiento con Ubuntu y funcionó, cosas que pasan.
Debido al descuido de algunos paquetes de GNOME bluetooth en Debian dejé apartado el tema. Desde entonces tenía esto sin publicar, y ya que lo tengo, lo dejo por si sirve de algo.

Se trata de un rápido howto para gestionar el bluetooth y conectar un ordenador con GNU/Linux a un nokia 6230. Tiene partes de gentoo y de vete tu a saber que más.
A parte, está en inglés.

1. Check the (USB) bluetooth adapter :

   usuario@LOCAL:~$ hciconfig -a
   hci0: Type: USB
   BD Address: 00:A0:96:20:2B:A0 ACL MTU: 128:8 SCO MTU: 64:8

   Manufacturer: Cambridge Silicon Radio (10)

2. If that seems ok then start bluetooth. First I disabled hdidd in /etc/conf.d/bluetooth since I don’t need it. You can keep it if you need :

   HIDD_ENABLE=false
   HIDD_OPTIONS=”"
   HID2HCI_ENABLE=false
   root@LOCAL:~$ /etc/init.d/bluetooth start
   root@LOCAL:~$ rc-update add bluetooth default

3. scan if bluetooth phone is here. if everything is ok then configure rfcomm in order to send/receive the file.

   usuario@LOCAL:~$ hcitool scan
   00:E0:03:36:90:2D Nokia 6230
   usuario@LOCAL:~$ sdptool browse 00:E0:03:36:90:2D

4. Only OBEX PUSH section interest, you have to check the channel. Here thi is 9. It should be the same for you. Then edit /etc/bluetooth/rfcomm.conf and add these lines. Then restart bluetooth.

   rfcomm0 {
   bind no;
   device 00:E0:03:36:90:2D;
   channel 9;
   comment “Nokia 6230 - benoitc”;
   }
   root@LOCAL:~$ /etc/init.d/bluetooth stop
   root@LOCAL:~$ /etc/init.d/bluetooth start

5. Check if everything is ok :

   root@LOCAL:~$ rfcomm connect rfcomm0 00:E0:03:36:90:2D 9
   Connected /dev/rfcomm0 to 00:E0:03:36:90:2D on channel 9
   Press CTRL-C for hangup

   exit

6. To enable fle sending/receiving I use GNOME-bluetooth. You can also use obexftp to do it in console mode.
   I use GNOME-blueooth 5.1 and openobex 1.0.1 (currently masked)
   Then launch Bluetooth File sharing in Application/System Tools menu (You could also use launch GNOME-obex-server in the terminal.

Note. I have to edit /etc/bluetooth/hcid.conf and change the value local device class from 0×100 to 0×100100 in order to allow my phone to find the computer.
class 0×100100;
Note 2: To change your PIN code edit /etc/bluetooth/pin.
