have you gotten this to work on the pc with the w2 card? it works fine on the android phone. Like i said i use 3 different computers, 3 different network adapter, and 2 different os's, not much left I can try here.
Managed to get it to work (with the original ESP8266 version) with a Mac, but needed an Android phone to set it up. Used DHCP to force my android phone on my usual Mac's address, set up the PSU, then moved all IP addresses back. Now the PSU thinks it's talking to an android phone, but it is a Mac. Don't use it much though, as I have other PSUs that speak a real instrumentation language (SCPI).
I got my head around this. I wasn't sure how to handle the software, but I justed need to click connect. So now I have it configured to point to my desktop. Appreciate this working perfect now. Would have been a lot easier to just let us program the ip, or the normal AP to input the wifi stuff, then switch to client mode.
