I tried recording with the Zoom F3 with the bluetooth adapter in my pocket the other day and had a unique failure mode. The app suddenly disconnected as the band came on. I managed to reach into my pocket and restart the recording (not the unit) manually. When I went to listen afterwards the recording was plagued by cut outs and loud clicks that essentially ruined it.
I have already thrown out the adapter as it has no value to me if it loses connection with the phone ~1' from my recorder. What I'm not clear on is whether this issue with it wanting to connect to bluetooth was the other issue or if the intermittent drop outs and noise were due to a cabling issue or related to the adapter.
Has anyone else had an issue with the bluetooth that resulted in the recording being interupted in this way (after the app was closed but the recorder had still been started with bluetooth connectivity on). It could easily also have been a loose cable but the way it popped in and out, when I was sitting still much of the time, has me thinking the bluetooth functionality may be a culprit.
