ArduinoJson 7 - DynamicJsonDocument is deprecated
francwalter opened this issue · 2 comments
With the actual ArduinoJson 7.0.3 I get, when compiling, the warning:
warning: 'DynamicJsonDocument' is deprecated: use JsonDocument instead [-Wdeprecated-declarations]
when I downgrade to ArduinoJson 6.21.5 the warning is gone. So the use of DynamicJsonDocument should be replaced by JsonDocument.
At the moment I downgraded my ArduinoJson to 6.21.5 but I guess it is not the best solution, I prefer to keep my libraries up to date.
You just have to take out the size of the structure - simple but lots of typing for the library master.

In fact, newer ESP32 core and newer ArduinoJSON causes too many errors: Some of them are listed below:
