I wrote a piece of code, just to try to connect to my local network ... and it works !!!
So: I suspect that the ".bin" provided (R120) uses old libraries and should be rebuilt.

Hello, After flashing several devices based on 8266 (3 DI mini pro, NodeMCU Lolin and Amica), I connected them successfully to ESP_0. My local networks appeared: fine, but next step failed: they didn't receive an IP address ! For a couple of days I tried with several devices, versions R120, R78, R14...

Hello,

As I was very happy with Sonoff "standard" (1 relay), I bought a few Dual version devices. I'm trying to flash them with ESP Easy ... without any success. It seems that the device is not responding.

Did you flash the device ? Any trick ?

Thanks
Kind regards
