"-" not declared in this scope fix

[AlexanderDNye]

I was having a few declaration errors, it seemed each time I would fix one another would pop up.

I found that the libraries used need to be at specific builds and not necessarily the newest build will work. Arduino IDE v1.8.10.0

Board Mangaer esp8266 needs to be at v2.4.1

Library Manger WifiManager needs to be at v0.12.0 ArduinoJson needs to be at v5.13.1 and the SSD1306 needs to be at v4

Hope this helps

The only one that I know is an issue taking the latest is the ArduinoJson and it is still in BETA last I checked. It is known and mentioned in the Readme file.

Hi AlexanderDNye and Qrome,

I checked the readme file and installed all the libraries but still having this error in writeSettings segment.

'readSettings' was not declared in this scope

version of the libraries was double checked. I miss something?

pablosimone - what version of Arduino are you using?

By the way, the project works just fine with:

Board ESP8266 Core at v2.4.2 And the latest WifiManager of v0.14.0

When core changed, it required WifiManager to change as well. They work with this code.
