So the story is, I’ve got a bunch of android-based smartwatches I’m using for some hobby projects. Got tired of typing stuff on a tiny 2" screen, so I’ve bought some rando bluetooth kbd/mice combo. Tried with the phone and it worked fine but I had a lot of trouble pairing them with the watches and even then it stutters a lot. Thought it was just watches being laggy until I noticed that they work much better if I move the watches away for me, or if I use the peripherals behind my back.

Obviously, having to do either is far from ideal. So the question is, am I going nuts, or is too much transmitting power a thing with BT devices? Is it just interference? Any tips on how I could reduce it?
