Unable to Connect Android App Openbot to Controller App

[A-janjan]

I have encountered an issue where the Openbot app is unable to connect to the Controller app. I have installed both of them and connected them to the same network, but they aren't connected to each other. Additionally, I have changed the controller type to phone.

What should I do?

Is there any log?

Make sure to open the controller app first and then connect to OpenBot by switching the controller mode to phone. If you're still facing issues, consider switching to a different device.

It didn't work for 3 devices; Are there any logs or things that can show me what happened backstage?

Yes, When successful connection establishes, in robot app log appears as "Client connected: IPv6 address of wifi". And if there comes any error it shows "Got exception: erorr ".

I am also facing the same issue.

The setup is pixel6a(controller) running a WiFi hotspot. Samsung Galaxy M31(robot) and also a laptop. Tried reversing the two phones. Also tried third phone hosting the hotspot instead of one of the two

I am able to control the car using the python scripts. in laptop but not with the controller app.

It works fine for me! Make sure that both the phones are on the same WiFi Network.

Did it work? if yes then please close this issue.

Yeah, but the main solution is changing the stream mode from RTSP to WebRTC. Thanks to all.
