January CP2AIR FW about wireless-carplay-dongle-reverse-engineering

[simon0117]

Quick update, I flashed the rollback image and it worked, then I went through several upgrades to get to U2W_Update_2021.08.30.0022.img (I presume), but then it said there was another upgrade which downloaded but failed.

VER:2021.12.22.1643 | Size:0.44MB
Release Notes:
Optimize memory usage

I tried with the dongle connected to my computer (Mac) as well as the normal way in the car.

In the car, I seem to have the same problem as before where starting the car with the phone wired into the dongle's USB says that it's connecting but never does. This may be because I'm testing this out in the garage while still connected to my home wifi, I dunno. During the upgrades I noticed the wifi SSID was sometimes AutoBox-582f, sometimes TOYOTA86 which I think is the "correct" one. Playing around with the wifi on the phone between my home wifi and the dongle wifi I get it to connect wirelessly quicker, but most of the time when I plugged it into the USB it would disconnect then reconnect wireless, indicating it was just using the USB for charging.

I'm not sure how to troubleshoot this exactly so I can see exactly what is going on with the failed upgrade or the wired/wireless connection. I could do stuff on my Mac like monitor the HTTP requests or something
