So I fired up a test platform.
Pi Zero 2 W
moOde 7.6.1
onboard WiFi connected in client mode
audio out: white box USB-headphone adapter -> earbuds
BT source: Qubuz app on Pixel 3a phone (Android 12)
I'm getting a roughly 1-second audio dropout roughly every 3 seconds (but the periodicity seems to vary).
If I disable WiFi until next boot (sudo ifconfig wlan0 down) then the dropouts cease.
Finding the WiFi signal strength and link quality is trivial but it's harder to find analogous BT measures to help diagnose, at least using the BT tools I'm aware of. I haven't found any telltale traces in syslog.
I get similar behavior if I run moOde in AP mode (the periodicity seems longer but I'm not measuring carefully).
I'm wondering if our differing experiences might be down to the WiFi channel being used. (Confession: naively, I thought adaptive frequency hopping would take care of this.)
My new, ISP-provided router/access point insists on using channel 1 (2.412 GHz) which falls in the lower part of the BT band (2.4GHz - 2.483GHz) and I haven't figured out yet how to force it up to, say, channel 11. [In the interest of domestic tranquility I'm waiting to experiment until my partner is reading a book IRL].
All my moOde players capable of 5GHz WiFi are connecting at to the AP at 5GHz and have been immune to this effect.
External USB dongles change the equation, of course, but make the Zero with its single microUSB port a poor choice.
Regards,
Kent
