N2+ with Harmony Hub (CSR dongle issue)


i recently purchased an ODROID N2+, installed CE19.5 and now trying to setup my Harmony Hub remote via bluetooth (I don’t want to use IR as it is not snappy enough, though it’s working).

I’m using a CSR dongle, bluetooth is enabled and device is connected (bluetooth devices show HARMONY KEYBOARD connected YES in Coreelec settings).
In my Harmony setup, i’ve added a device Microsoft Media Player (Manufacturer: Microsoft, Model Number: Kodi) (it was working with my KVIM3 + internal bluetooth)

So, all appear to be setup correctly, but the remote is simply not working. I press up, down buttons etc. nothing is being registered.
In last resort, i may purchase the official dongle sold by odroid (5BK, but i’d prefer to save few bucks and have my current dongle working.

Any idea what i could do/try ?

Thank you

So i decided to get the official BT/WIFI dongle from Hardkernel, but still cannot pair/connect.
I got “operation currently not permitted” and “did not receive a reply” error.
Guess BT is broken with N2

even when i got mines working it wasn’t a good experience,ended up buying a cheap infra re remote

well, my harmony always worked wonderfully with my previous boxes (C2, minix u9h, KVIM3), it shouldn’t be any different with the N2, will do further tests.
