• pak by měla fungovat normální klikačka přes gnome-bluetooth asi
  • https://wiki.debian.org/BluetoothUser

• tak ještě by chtěl ten BNEP a RFCOMM TTY

• Bluetooth v testing je ve verzi 3.36!!!
• v unstable je uz verze 4.40!!

• novy bluez = stary bluez-utils + bluez-audio

• rozdily:
  • bluez-gnome 0.27 vs 1.8!!
  • bluez-utils 3.36 vs 4.42
    • 3.36: hcitool, hidd, rfcomm, hciattach, hciconfig ….
    • 4.42: This is a transitional package to assist with moving people to the BlueZ 4.x stack.

• chce to prespat /etc/default/bluetooth.. tam jsem menil jenom:

# HID daemon
HIDD_ENABLED=1
#HIDD_OPTIONS="--master --server"
HIDD_OPTIONS="--server"

• rucni pripojeni na HID:

sudo hidd --connect 00:0F:DE:A8:71:24

• bluez-gnome, bluez-utils, bluez-hcidump
• gnome-vfs-obexftp - podpora obex v nautilusu
• obex-data-server - bez neho nesli odesilat soubory pres ikonu bluetooth :)

• http://www.root.cz/clanky/jak-na-bluetooth-pod-linuxem/
• http://www.linuxsoft.cz/sw_list.php?id_kategory=99

• Ze všeho nejdříve ovšem musíme „nahodit“ Bluetooth zařízení, aby o nich jádro vědělo:
  • modprobe hci_usb; #popřípadě jiný driver v závislosti na vašem železe
  • hciconfig hciX up; #hci0 - prvni dongle, hci1 - druha dongle…

• Abychom nemuseli řešit problém, že na náš desktop se nám připojuje aplikace běžící pod rootem (hcid), zadáme xhost +. Vyjede na nás okénko, kde zadáme to samé číslo a potvrdíme. Zařízení

• kde se ulozil ten nazev pharaon?
  • musi se nahodit linka… pres hciconfig….
  • potom spustit nejake sluzby.. treba pres kdebluetooth… ten vyzaduje deamona sdpd pro chat a tu druhou blbost

• soubor rfcomm
  • slouzi k vytvoreni virtualnich seriovych linek TTY
  • definuje se dycky s jakym zarizenim, na jakym kanale…
  • zatim jsem nenasel jeste vyuziti :) mozna presmerovani RFTTY do VBoxu
• napr:

rfcomm0 {
        # Automatically bind the device at startup
        # automaticky pripravit TTY /dev/rfcomm0 pro BT zarizenim
       bind yes;

        # Bluetooth address of the device
        # BT HW adresa ciloveho zarizeni
       device 00:0F:DE:A8:71:24; #moje K700

        # RFCOMM channel for the connection
        # Kanal pro komunikaci
       channel 1;

        # Description of the connection
#       comment "buldokova k700i";
#}

• nastaveni .gammurc —pouziva se i pro wammu

[gammu]
synchronizetime = no
name = Sony Ericsson K700i
logformat = nothing
connection=blueat
model=auto
port = 00:0F:DE:A8:71:24

• Jak rozchodit handsfree (headset) pres bluetooth
• existuji dva protokoli:
  • high definition audio = A2DP
  • telephone audio = SCO

• pro handsfree se pouziva SCO
• domaci stranka projektu: http://bluetooth-alsa.sourceforge.net/
• navod na rozchozeni: http://www.linux.ie/articles/bluetoothheadset.php

• muj postup
• v systemu uz mam funkcni bluetooth rozhrani.

apt-get install bluetooth-alsa
