The problem with OS from OrangePi is that it's v0.2 and its smelly and buggy 3.10.x kernel will stay there forever.

There is one crazy issue with AP6212A and AP6212. They both seek for the firmware in the same place while they need a different one. Type AP6212A in a search to get insights.
 
 
I have no idea if low energy Bluetooth functions are working - we usually end our testings when some HID device is able to connect. In any case you have way more chances of success with modern kernel 4.12.x, which is at least supported and is getting fixes on daily base.
 
 
Not much is usable from that kernel since its too big difference. Most of core functions were written from scratch - you can monitor progress here.

Thanks for your replies. A litte more progress by installing the debian OS from orangepi.org  (debian_jessie_zeroplus2_H5_V0_2.rar). This version enables the micro USB OTG (host mode) for use with USB hub, mouse and keyboard, WIFI worked immediately from the desktop setup. Unfortunately, bluetooth seems non-existent on this version. Having read the Armbian details on the AP6212A WIFI and bluetooth combo chip, I'm assuming the AP6212A firmware files are pretty much standard regardless of which OS is running? I don't see the firmware files even exist in the /lib/firmware/ folder for the above OS. To get bluetooth and bluetooth Low Energy working, is it a matter of configuration settings to enable the AP6212A's bluetooth function? I realize of course, the above OS is not Armbian, thought it may help with the micro USB OTG (host) setup in the Armbian OS. Any ideas on how bluetooth can be enabled, followed by bluetooth Low Energy function/setup? Thanks again....
