I had an interesting experience the other day. I bought one of those psychedelic night lights that project stars on your ceiling, and I thought I'd play some music at the same time. I couldn't get my bluetooth speakers to connect solidly. They would start playing and then reset and disconnect. I turned off the nightlight and turned on the lights to figure out what the problem was and they connected immediately perfectly. Turned the nightlight back on and the speakers disconnected. Apparently the nightlight was putting out some sort of bluetooth interference. I had a similar problem with a smart light. The middle TV channels would occasionally be unreachable (I use an antenna). After about six months I figured out that there was just one bulb in the room that was causing the problem. Turn it on and the middle channels disappeared, turn it off and they were perfect. Interference is a problem and sometimes it can be difficult to figure out where it's coming from.
