I am using an unedited Basic.ino from the painless library.
Am getting a variety of errors.
The first is;

Error while detecting libraries included by C:\Users\Grant\Documents\Arduino\libraries\ESPAsyncTCP-master\src\ESPAsyncTCP.cpp

But it still compiles past that point.
Then I get a sea of red errors :

C:\Users\Grant\Documents\Arduino\libraries\painlessMesh-master\src/painlessmesh/protocol.hpp: In member function 'virtual ArduinoJson::JsonObject painlessmesh::protocol::Single::addTo(ArduinoJson::JsonObject&&) const':

C:\Users\Grant\Documents\Arduino\libraries\painlessMesh-master\src/painlessmesh/protocol.hpp:82:12: [b][b]error: use of deleted function[/b][/b] 'ArduinoJson::JsonObject::JsonObject(const ArduinoJson::JsonObject&)'
return jsonObj;
^

Any ideas....

I have found that I still get errors with a sketch that only has the line
#Include "painlessMesh.h"
Is this a clue on what I've done wrong?

- Mon Aug 24, 2020 4:00 am #88455 ArduinoJson made major changes to its API between v5 and v6 so it is possible there is a version conflict between that and painlessMesh.

Either painlessMesh expects v5 and you have v6 installed or vice versa.

Took your hint and reinstalled all libs.
It now compiles and runs ok,
The link is:
https://iotdesignpro.com/projects/creat ... ideVesions and libs are:
Using library Painless_Mesh at version 1.4.5
Using library TaskScheduler at version 3.1.6
Using library ArduinoJson at version 6.16.1
Using library ESP8266WiFi at version 1.0
Using library ESPAsyncTCP-master at version 1.2.2

Tks for our help in putting me on the right track.
