カーネルの設定

If you are building this package to use bluetooth devices (rather than as a build dependency), enable the following options in the kernel configuration, also the options below the next paragraph if you intend to run the tests, and recompile the kernel if necessary:

[*] Networking support --->                [CONFIG_NET]
  </M> Bluetooth subsystem support --->    [CONFIG_BT]
    <*/M> RFCOMM protocol support          [CONFIG_BT_RFCOMM]
    [*]   RFCOMM TTY support               [CONFIG_BT_RFCOMM_TTY]
    <*/M> BNEP protocol support            [CONFIG_BT_BNEP]
    [*]   Multicast filter support         [CONFIG_BT_BNEP_MC_FILTER]
    [*]   Protocol filter support          [CONFIG_BT_BNEP_PROTO_FILTER]
    <*/M> HIDP protocol support            [CONFIG_BT_HIDP]
        Bluetooth device drivers --->
          (Select the appropriate drivers for your Bluetooth hardware)

  <*/M> RF switch subsystem support --->   [CONFIG_RFKILL]

If you wish to run the testsuite (even if treating this package as a build dependency), you will need to enable the following options in the kernel configuration and recompile the kernel if necessary:

[*] Networking support --->                                     [CONFIG_NET]
-*- Cryptographic API --->                                      [CONFIG_CRYPTO]
  </M> User-space interface for hash algorithms                 [CONFIG_CRYPTO_USER_API_HASH]
  </M> User-space interface for symmetric key cipher algorithms [CONFIG_CRYPTO_USER_API_SKCIPHER]

BlueZ のインストール

以下のコマンドを実行して BlueZ をビルドします。

./configure --prefix=/usr         \
            --sysconfdir=/etc     \
            --localstatedir=/var  \
            --enable-library      &&
make

ビルド結果をテストする場合は make check を実行します。

root ユーザーになって以下を実行します。

make install &&
ln -svf ../libexec/bluetooth/bluetoothd /usr/sbin

root ユーザーになって、主要な設定ファイルをインストールします。

install -v -dm755 /etc/bluetooth &&
install -v -m644 src/main.conf /etc/bluetooth/main.conf

API ドキュメントが必要な場合は root ユーザーになって以下を実行します。

install -v -dm755 /usr/share/doc/bluez-5.50 &&
install -v -m644 doc/*.txt /usr/share/doc/bluez-5.50

コマンド説明

--enable-library: This switch enables building the BlueZ 4 compatibility library which is required by some applications.

ln -svf ../libexec/bluetooth/bluetoothd /usr/sbin: This command makes access to the bluetooth daemon more convenient.

BlueZ の設定

設定ファイル

/etc/bluetooth/main.conf is installed automatically during the install. Additionally, there are three supplementary configuration files. /etc/sysconfig/bluetooth is installed as a part of the boot script below. In addition, you optionally can install the following, as the root user:

cat > /etc/bluetooth/rfcomm.conf << "EOF"
# Start rfcomm.conf
# Set up the RFCOMM configuration of the Bluetooth subsystem in the Linux kernel.
# Use one line per command
# See the rfcomm man page for options


# End of rfcomm.conf
EOF

cat > /etc/bluetooth/uart.conf << "EOF"
# Start uart.conf
# Attach serial devices via UART HCI to BlueZ stack
# Use one line per device
# See the hciattach man page for options

# End of uart.conf
EOF

Systemd Bluez Services

To start the bluetoothd daemon at boot, enable the previously installed systemd unit by running the following command as the root user:

systemctl enable bluetooth

To start the obexd daemon for a user session (to support some Bluetooth programs using it), enable the previously installed systemd unit for all users by running the following command as the root user:

systemctl enable --global obex

[注記]

注記

Systemd will start the Bluetooth daemon only when a bluetooth device is detected on the system.
