Oculus Quest 2 Connection to an Arduino via Bluetooth is highly unreliable

I'm having trouble successfully connecting an Arduino to my Quest 2 using Bluetooth. In the Bluetooth devices section I can see the Arduino, but sometimes I can't even pair with it for apparently no reason. Whenever I do pair with the Arduino (by repeatedly forgetting and restarting both devices), it usually just stays paired, but pressing "+ connect" does nothing and the keyboard functionality doesn't work. Then I have to repeat forgetting and re-pairing the Arduino until after multiple tries it finally does pair and seems to be connected. At this point the devices function well and it is possible to use Arduino to send key-presses to Quest 2. However at any point the connection might silently drop for seemingly no reason and I have to start the entire process from the beginning.

Is the unstable connection to Bluetooth devices a known issue? Are there any tips or suggestions to things I could try to stabilize them and help them connect first try?
