    124 {{{
    125 /etc/bluetooth/main.conf
    126 }}}
    127 file to the desired values. It is recommended that you set the DiscoverableTimeout and PairableTimeout to 0 to disable them for testing purposes.

    129122=== Setting Up a Connection ===
    130123'''Using bluetoothctl'''
    1311241. Start {{{bluetoothctl}}}
    132 If your controller is set up properly, the first thing to display should be the MAC address of your Bluetooth controller. Bluetoothctl will then provide a prompt {{{[bluetooth]# }}}
    133 
    134 2. Run {{{show}}} This should list the configuration information for your Bluetooth controller.
    135 3. Run {{{devices}}} This provides the user with a list of available devices. If you have not scanned yet, this list may be empty except for your own Bluetooth controller.
    136 4. To enable the controller and prepare for pairing with a device, run the following:
     125 1. If your controller is set up properly, the first thing to display should be the MAC address of your Bluetooth controller. Bluetoothctl will then provide a prompt {{{[bluetooth]# }}}
     1261. Run {{{show}}} This should list the configuration information for your Bluetooth controller.
     1271. Run {{{devices}}} This provides the user with a list of available devices. If you have not scanned yet, this list may be empty except for your own Bluetooth controller.
     1281. To enable the controller and prepare for pairing with a device, run the following:
    137129{{{
    138130[bluetooth]# power on
    … …  
    145137Changing pairable on succeeded
    146138}}}
    147 5. To search for available Bluetooth devices, enable scanning with {{{scan on}}} This will begin listing all devices transmitting within range. Turn this off anytime with {{{scan off}}}
    148 6. Once you find the device in the scanning list, trust the MAC address and then connect:
     1391. To search for available Bluetooth devices, enable scanning with {{{scan on}}} This will begin listing all devices transmitting within range. Turn this off anytime with {{{scan off}}}
     1401. Once you find the device in the scanning list, trust the MAC address and then connect:

    154146}}}
    155 7. If the connection is successful, run {{{info XX:XX:XX:XX:XX:XX}}} to see information about the device you are connected to.
    156 8. {{{quit}}}
     1471. If the connection is successful, run {{{info XX:XX:XX:XX:XX:XX}}} to see information about the device you are connected to.
     1481. {{{quit}}}
    157149''Tip: Known MAC addresses can be tab completed in Bluetoothctl.'' Note: To automate bluetoothctl commands try using
    158150{{{bluetoothctl -–command}}}
    159151
    160152'''Using hcitool'''
     153
    1611541. Run the init scripts to setup the HCI interface (if you have not already)
    162 2. Scan for the desired MAC address
    163 {{{hcitool -i hci0 lescan | grep <desired MAC>}}}
     1552. Scan for the desired MAC address {{{hcitool -i hci0 lescan | grep <desired MAC>}}}
    164156a. MAC in format XX:XX:XX:XX:XX:XX
    165 3. Start the connection
    166 {{{hcitool -i hci0 lecc --random <desired MAC>}}}
     1573. Start the connection {{{hcitool -i hci0 lecc --random <desired MAC>}}}
     158
    167159'''Using LE Coded PHY'''
     160
    1681611. Run init scripts to setup your HCI UART connection (if you have not already)
