V355 bug

Did you update the firmware in the ESP8266 WiFi module when you updated the clock? If not, that is probably the problem.

v355 is not compatible with v353, there was a change in the I2C protocal to let the MinDim setting to be managed.

If you go to v355 on the clock code, you need to go to v355 on the Wifi module code, and vice-versa!

Yes, i updated the esp and the atmega, reverting back to 353 solved the problem

Just to follow up... I was able to reproduce the problem here with Rev.2 V.355 when I loaded it on my Modular clock and WiFi module. It's a legit bug, the source of the problem has been located, and Ian tells me he's fixed it and will make it available very soon. Not sure if it will still be called 355 or rolled to 356.
