    ## Services

    All the services are launched from `/etc/init.d/startup`

    ### Disabling bluetooth

    Edit the file `/etc/init.d/startup/S13bluetooth.sh` and comment the last line:
    ```sh
    #!/bin/sh

    FACTORY_DIR=/mnt/factory_setting
    BT_MAC_FILE=${FACTORY_DIR}/BT_MAC_ADDR
    BT_CAL=mrvl/BTCalData_sd8897.conf

    get_bt_mac_address() {
    # Get mac address from file and insert semicolons between octets:
    # 021122334455 => 02:11:22:33:44:55
    cat $BT_MAC_FILE | sed -r 's/(..)(..)(..)(..)(..)(..)/\1:\2:\3:\4:\5:\6/'
    }


    # Bluetooth
    # note: the bluetooth module must be insmod'ed after wifi or else the
    # chip firmware is not loaded properly and bluetooth will fail to work
    if [ -f "${BT_MAC_FILE}" ]; then
    BG_MAC_ARG="bt_mac=$(get_bt_mac_address)"
    else
    echo "warning bluetooth mac address file not found: ${BT_MAC_FILE}"
    fi

    echo "modprobe bt8xxx ${BG_MAC_ARG} cal_cfg=${BT_CAL} psmode=0"
    modprobe bt8xxx ${BG_MAC_ARG} cal_cfg=${BT_CAL} psmode=0

    #/etc/init.d/bluetooth.sh &
    ```

    We can't simply remove `/etc/init.d/startup/S13bluetooth.sh` because `S15audio.sh` relies on it using BlueALSA backend.


    ## Tunning
    ### Bandwith

    ```sh
    cd /mnt/config/system
    echo "--hardwarebitratelimit 50000" > streaming_args.txt

    ## Disable services
    echo "CAMQABgAIAAoADCgjQZAAA==" > streaming_settings.b64
    base64 -d streaming_settings.b64 > streaming_settings.bin
    rm streaming_settings.b64
    ```

    `/etc/init.d/startup` contains all the scripts used to startup services.
    You can move some of these scripts to a folder like `/etc/init.d/startup_disabled` so they will no longer loaded at startup.
    Binary file has been dumped using:
    ```sh
    base64 streaming_settings.bin
    CAMQABgAIAAoADCgjQZAAA==
    ```
