54 ODROID-XU4 USER MANUAL
To congure the adapter from the Ubuntu desktop, launch the
Bluetooth Manager conguration utility from the System → Preferenc-
es menu item. Then, select the Adapter → Preferences menu item
to congure the application. Keep the friendly name of the Bluetooth
adapter as “odroid-0”. You can make the device always visible when
other Bluetooth devices scan for this adapter. The image above shows
the conguration screen. After conguring, save the changes and re-
boot.
If there is a need to test or debug issues related to the adapter,
you can use the command line Bluetooth packet analyzer/sniffer tool
called “hcidump” to analyze the Bluetooth trafc. This tool does not
have a prebuilt package, so it needs to be built from source using the
following steps:
$ sudo apt-get install autoconf
$ cd ~/
$ mkdir hci
$ cd hci/
$ wget -c http://www.kernel.org/pub/linux/bluetooth/bluez-hcid-
ump-2.5.tar.xz
$ tar xvfJ bluez-hcidump-2.5.tar.xz
$ cd bluez-hcidump-2.5
$ autoconf
$ automake --add-missing
$ ./congure
$ make
$ sudo make install
$ sudo hcidump

Debug Bluetooth trafc using hcidump
Using a device that has Bluetooth support, enable it and scan for
the XU4’s Bluetooth device called “odroid-0”. Select it in order to pair
it with the XU4. Debug information will appear in the terminal instance
where the hcidump utility was started, as shown in the image above.
