what power supply you used for A8?
in your video there is RED cable connect to i2c bus extender, what's this use for?

Hi! power supply is 12v 5A with 2 battery
Red cable used to power on another ESP8266. Yesterday i remove this cable and power on ESP8266 by usb - with same result - connection lost...

Next i find KCS v2.2.2 and install it - so, it work more than 6 hours now, and connection is OK!

I will observe, but i hope the problem is solved.
Thank You!

ok, i will try another power supply today later

now A8 is failed again (((
