Choose different subnet for configuration mode IP #56

Closed mountaindude closed 8 years ago

mountaindude commented 8 years ago

The 192.168.1.1 net is quite often used by SOHO routers. Placing a homie device in config mode on that same IP might easily cause conflicts with the user's cable modem/router/Internet gateway.

Maybe something like 192.168.50.1 (or something similarly infrequently used subnet)?

Or provide a way for the developer to define the desired subnet themselves?

I guess one could also change the Homie source.. Looks like the 192.168.1.1 is defined in the src/Homie/Boot/BootConfig.cpp file (I am using Homie together with PlatformIO, btw)

...then again, changing the access point's IP address to 192.168.50.1 breaks the config tool at http://marvinroger.github.io/homie-esp8266, it seems...

The problem is changing the default 192.168.1.1 would be a breaking change. And 192.168.50.1 might also be used by someone else! So yes, maybe we should move the apIp variable to the Constants.hpp, so that it is easily customizable.

It should not break the config tool, it tries to reach http://homie.config, and as you can see, the DNS server is tied to the apIp.

Is it enough for you?

mountaindude commented 8 years ago

Yeah it sounds like a good plan.
