SOLVED IT! Here, You can use this, hope it helps out! UNITV2 WEB RESULT RESPONSE

I reboot with terminal and try LaneLine Tracker setting. but I had same problem... I try it: Power on and start UnitV2 . Click gear icon and select "Switch to notebook mode". Open Jupyter main page. Click "New" and select "Terminal". type "reboot" and open camera stream page. Click little switch and there color change black to light blue. Select "LaneLine Tracker" on Browser GUI. Change L_max text box value 0 to 30 . Click “update” button. Line tracking process is stopped. but camera stream keep running. Maybe, I think my unitV2 need initialize firmware. Where is unitv2 initialize procedure?

@m5stack This is a very big issue, The M5Stack team needs to get this working, and the wifi access point!

A new version of the firmware is comming soon ... https://community.m5stack.com/topic/3321/unit-v2-connection
