Thanks looks like this was changed in 2.4.0
esp8266/Arduino@4dc4e75

tablatronix · 2018-03-27T17:37:08Z

how in the hell does one install 2.3.0 on platformio.hmm

sidey79 · 2018-03-28T20:45:48Z

Sorry, no idea.

It's boring, that the upstream lib is changed that way.

tablatronix · 2018-03-28T20:51:02Z

I will see about making this backward compatible, not sure how I can use strings and char* and use flash strings, ideas prs welcome

sidey79 · 2018-03-28T21:11:29Z

The only think i see is, that it is possible to detect the lib version via #ifdef ....

Something like this:
#ifndef ARDUINO_ESP8266_RELEASE_2_3_0

And depending on the version use seperate code.

Not very well but then it is backward compatible

Yeah the event func was changed in 2.4 and not backward compatible.

asyncscannetworks not available in esp8266 2.3.0, adjusted server on to take cstr for backwards compatability

tablatronix · 2018-09-07T19:57:29Z

using server->on(String(FPSTR(R_root)).c_str(), for both compatability

bayazidsustami · 2018-10-05T08:55:23Z

it's not work on my pc

using server->on(String(FPSTR(R_root)).c_str(), for both compatability

May I know where to add this line in WifiManager.cpp?
