I2C + ArduinoJson about arduinojson

[bblanchon]

It's quite simple actually.

First you create your JSON object:

JsonObject<6> json; 
json["key"] = "value";
// etc.

Then you write into the buffer

char buffer[32];
json.printTo(buffer, 32);  

But I think there is a better way.
Since Wire implements Print, you can write:

Wire.print(json);

This will send the JSON via I2C without any buffer 😎
