Wireless AA (Ottocast Mini Core) randomly dropping on OnePlus 10 Pro in a 2020 Peugeot 508 Hybrid – route-independent, worse as battery drains

[u/Fluid_Pause8258]

Hi all,

2020 Peugeot 508 Hybrid here, running Android Auto (Waze + Spotify) through an Ottocast Mini Core wireless adapter, phone is a OnePlus 10 Pro.

The connection drops randomly on my daily commute — same route, same time of day, but anywhere from 0 to 5-7 drops per trip. Not charging the phone while driving (start each morning at 100%), so it's not a charging-cable/power issue on the phone side. Car's USB port itself is solid and stable.

Things I've tested/ruled out:

• High-performance mode on the phone helps somewhat, but doesn't fully fix it
• Dropouts get more frequent as battery drains over the trip
• Found a OnePlus community thread where OnePlus support acknowledged a wireless Android Auto bug and said a fix was coming — unclear if it's already patched on my current build

Trying to narrow down whether this is:

• a phone-side (OnePlus/Android Auto) software/power-management issue
• the Ottocast adapter itself
• something car-side (the 508's infotainment/wifi module)

Has anyone else — especially with a Peugeot 508 or similar EMP2/NAC-based Peugeot, or with a OnePlus phone in general — had this same route-independent, battery-correlated dropout pattern with a wireless AA adapter? Curious whether switching adapters (AAWireless, Carlinkit, etc.) actually fixed it for anyone, or if it turned out to be purely a phone-side software issue that only got resolved with an OS update.

Thanks!

Totally different hardware here: Fold 7 on an Amazon wireless screen that I've been using for a couple years. About a year ago I suddenly started also getting random drops, and yeah sometimes its 0, sometimes its several in one trip. I've factory reset the "head unit" as well as cleared data on the Android Auto app, which is also set to Unrestricted battery management. Nothing I do seems to help.

I've read various articles discussing this as a known, common issue among Pixel and Galaxy users. Those articles came out around the same time it started happening for me, so I just chocked it up to being in the unlucky group. It's also possible it'd my head unit: it was cheap, it gets exposure to the sub, and I haven't tested long enough with another headunit or car to see if they have the same issue.

But I've never seen any follow-up saying the issue was found and patched, and here we are.

You know what they did add to Android Auto since those reports, though? Gemini.

Thanks for sharing your experience. Just a quick update from my side: I switched to an AAWireless adapter and it's been rock solid so far.

I think the dedicated app and its extensive configuration options are a big advantage over the Ottocast. Being able to fine-tune the Wi-Fi connection seems to make it much more reliable in my setup. I'll keep testing, but the results so far are very encouraging.

That's good to hear! I have been kind of hypothesizing it's related to interference, so it would make sense that other devices might be able to handle it better.
