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

[MartieTheSmartie]

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

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
When I go to the Arduino Library I don't have ArduinoJson
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..

In my case, I've determined that the problem was that the deauther board package that is required to be installed via the board manager (http://phpsecu.re/esp8266/package_deauther_index.json) includes the ArduinoJson library. On my Windows system, it was found here after installation:

%USERPROFILE%\AppData\Local\Arduino15\packages\deauther\hardware\esp8266\2.0.0-deauther\libraries

I deleted the ArduinoJson directory located there, and then installed the latest version 5 iteration (in my case, version 5.13.4) via the IDE Library Manager . This will install the ArduinoJson lib in your Documents folder (specifically, %USERPROFILE%\Documents\Arduino\libraries).

Oddly, the ArduinoJson library included with the deauther board package appears to be a valid version (5.13.0)... but I still got the upgrade/downgrade error message until it was deleted. Haven't had an issue since.

[tobozo]

@labomb @jumblies thanks for reporting this, the deauther SDK is now bundled with ArduinoJSON 5.13.14

you will need to remove/reinstall the deauther SDK from the boards manager to see the effects though

can you please confirm this action fixed the issue ?

[labomb]

@tobozo that took care of the problem. I removed the locally installed ArduinoJson lib and removed/reinstalled the deauth board package as requested and it appears that the updated ArduinoJson library that is now bundled works fine... no version errors during build. Thanks for the update.

[nc9710]

Followed advice by spacehuhn and resolved issue. I also deleted previously installed libraries which got rid of some warnings I had while compiling. Also, a quick work around (if engaging in the deauther project) is to download the latest bin file and use the ESP8266Flasher.

[tytower]

Importantly for those installing on Arduino , now until they change to ver 6 you can install the Arduinojson version 5 but the error message then will tell you you have 2 Arduinojson libraries and importantly will give you the address of the version 6 it tried to use . Note that directory address down ,go there and delete the whole file first then restart.

Hello there,
i checked every setting. Downgraded ArduinoJson library to version 5.13.4.
I tried everything that was mansioned here but still the same problem:

you still have two versions, you can safely delete the first folder (Benutzt)

comment 17,21,22 line, install 5.x, works for me

Thanks man!

[James0329]

I got a strange problem. friends.

If I don't delete checker all things will stop at version checker.
If I delete the version checker method.
Then install any 5.x ArduinoJson when I upload file to esp8266 will trigger a error like
"invalid initialization of non-const reference of type 'ArduinoJson::JsonArray&' from an rvalue of type 'ArduinoJson::JsonArray'
"
or
"no matching function for call to 'ArduinoJson::DynamicJsonBuffer::DynamicJsonBuffer(int)'
"
this problem location at ssid.cpp file.
"DynamicJsonBuffer jsonBuffer(4000);"
"JsonArray & arr = obj.get(str(SS_JSON_SSIDS)); "
I try 5.0.0|5.0.5|5.1.0|5.4.0 but nothing change.
Need some help (T_T)

[5ch4um1]

had this issue yesterday, but somehow it went away, i tried a few versions of ArduinoJson, to no avail, but today it works, not sure if it was the logout (restart in my case) ? I also deleted the repository and cloned it again, but i guess this shouldn't make a difference?
