ERROR: Please upgrade/downgrade ArduinoJSON

Having an error when compiling, ArduinoJSON is v5. Please help.

I am too facing the same issue.

[forseenink3238]

Me too but the source Is actually having a problem

Same problem @spacehuhn is this fixable?

[spacehuhn]

The obvious fix is to comment out the 3 lines (17,21,22) that are causing the error:
https://github.com/spacehuhn/esp8266_deauther/blob/master/esp8266_deauther/esp8266_deauther.ino#L17

But you still have to install the correct ArduinoJSON library version!
Check the Arduino library manager, your Arduino library folder and select the right board (under deauther not esp8266 section).

[spacehuhn]

Check your Arduino library folder (C:\Users\user\Documents\Arduino\libraries) and delete the ArduinoJSON folder if it exists.
If the library in there is the wrong version, you might not be able to up/downgrade it from the Arduino library manager, so you have to delete it maybe.
The problem is that Arduino gives priority to the libraries in your Documents\Arduino folder instead of the one that comes with the deauther pboard ackage.

Pro Tip: Read the error message carefully! It usually tells you the error 😉

In this folder is not ArduinoJSON folder only readmme datei

please help

I think the error message is trying to tell you to do this :

[pjvander]

Quick note about a mistake I made, if you're still having trouble. I had a newer ESP8266 board installed (2.5.0b I think) when I installed ArduinoJson. Went back and installed 2.0.0 but was still having issues with ArduinoJson until I removed/re-added it. HTH

Hello
When I go to the Arduino Library I don't have ArduinoJson
What can I do?

Still not working.....
What I have done...

1. Deleted the JSON folder from Documents/Arduino
2. Downloaded Arduino JSON V 5.0.0 from page: https://github.com/bblanchon/ArduinoJson/releases?after=v5.1.0-beta.1
3. Included in IDE.
4. Selected Node MCU 12E from Deauther Module section
   But still problem is there..

Hello

What can I do?

Download it from https://github.com/bblanchon/ArduinoJson/releases?after=v5.1.0-beta.1
and add it to Documents/Arduino then go to sketch tab in Arduino IDE and include it from there..
