While some of the required software modules may already exist
in your ODROID-C2’s installed image, it is helpful to install the follow-

$ sudo apt-get install bluez-dbg bluez-tools bluez-hcidump
$ sudo apt-get install bluewho blueman python-bluetooth
Some of them could be used to debug your setup, if you use
a non-Hardkernel Bluetooth adapter. You can check the Bluetooth
adapter’s support for additional features by examining the dmesg logs,
using the following command:
$ dmesg | grep Blue
