I am trying to build some of the bluetooth terminal tools such as hcitool and obexftp for Android with NDK. However, from what I understand, the libbluetooth.so, which was included in several Android implementations of hcitool, hcidump, obexftp no longer works since the bluetooth stack on most recent Android has changed.
Specifically, I need obexftp to be able to perform bluetooth ftp transfer between two Nexus 5 and OnePlus One phones. Here are links to few implementation of tools from 5-6 years ago which no longer work. I am getting error Device not found.

Does anyone know which libbluetooth.so file I need now or do I need other libraries to be able to use bluetooth stack?
My current phones have Cyanogenmod 12.1 and Android 5 Lolipop.
BlueZ (standard linux bluetooth stack) has been replaced with bluedroid (originally by Broadcom, now open sourced) in Android 4.2.
There is no easy way to make old bluez tools work with the new stack.
