Hello,
I followed the tutorial to connect my Grove Vision V2 and a XIAO ESPC3 to Home Assistant.
I flashed the XIAO like described, I got the Grove Vision running and detecting things but when I entered my wifi credentials, nothing happens.
I use a 2.4ghz network with a wep2 & 3 and have a lot of other ESPs running in it just fine.
What’s the best way to debug my problem? The log isn’t showing anything that’s related to wifi.
Hi there,
And Welcome Here…
So most obvious is Antenna, be sure it’s connected properly , those c3’s can be tricky.
The only other suggestion would try the “WPS demo” code on it ,if your Router/AP supports it.
Eliminates the Creds part of the connection.
It’s on here with the code , download that and drop it on the c3 if it works , then that eliminates any hardware issue’s and puts you on too the HA side of stuff.

curious to know , was this c3 ever connected to a wifi b4? 
Some routers have security settings or MAC address filtering that could prevent new devices from joining the network.
It’s more than likely it’s NOT the router or AP MAC filtering, if so the others would have required edit of the rules, etc. shot in the dark though to check, can’t hurt…LOL
Try the WPS demo code does it connect or no?

XIAO connects just fine via WSP to Wifi. When I try it in combination with the grove vision and the firmware provided in the tutorial, there isn’t even a request to the router.
Hi there,
Ok, Good The WPS connects fine.
Is the USB -C connection connected?
can you enable some debugging in the IDE tools for the ESP boot? see what it reports.
I got one from the LiveStream give away, haven’t set it up yet , so You are way ahead of me… 
I’ll look over the wiki and guide, What camera do you have? any good? THNX

Plugging in the ESP, Arduino IDE shows me this:

I can connect to the AP via Smartphone.
I dont know how to debug while the ESP is connected to the Grove Vision, i get no Logs at all.
SenseCraft shows no usable Log and the Arduino IDE is empty too when connected to the ESP.
Hi there,
So I just opened the one I have up, Connected it to the IDE with nothing mounted (Xiao) wise, No camera, The port is Connected at 921600 baud, I get a Log output that’s this?

But it does work and output something, check that with yours.
I’m plugged into the VisionAI board , no Xiao, No camera.
Black button is reset.
