Issue with bluetooth

Tinkering

Hi,

Not sure if this one goes here… but long time ago someone recommended Bluetooth transmitter REIYIN as a stable one … but what is happening my DietPi running on Odroid xu4 contains multiple lines in dmesg that device is still disconnected / reconnected… I tried also other ARM PC … same behavior … any idea what’s going on here? These disconnects results that zone in Roon disappears.
