Hello Garuda users.
When I login after reboot the Bluetooth speaker connects automatically. However after about 2 minutes idle the speaker disconnects. I connect the speaker again, and it disconnects after 20 minutes idle thereafter. I figure this is designed behavior, and I'm hoping the design includes other options. 
I can see this interaction between devices using btmon. For example, here is a disconnection finishing:

It looks like a "request to disconnect" from the speaker. I should be able to respond in the negative, is that correct?
I think previously I had used an HDMI connection to the speaker to avoid this issue, although my recollection is hazy.
I've spent a few hours searching around but haven't found the info I need to even create a sufficient search.
