Benoit, this is one of the best programming videos I have seen in a while. Clear, concise, and well laid out. It's obvious you spent a lot of time setting this up and working on the presentation. Thanks and Kudos!
Phenomenal presentation!! Just bought the eBook in part because I can't begin to imagine the amount of time you've put into this and it's already been a massive help!
Thanks, Ed! Indeed, it took me quite a lot of time to prepare this video; that's why I rarely publish a new video even though I have many ideas for them.
Thanks for your video tutorials and explanations, i love your french accent because i'm also french speaker and so je comprend bien mieux ton anglais que celui d'un natif 😉😉 @+
hey, really appretiate your contribution at arduino json library that you created. I am having a memory issue on my esp 32, could you please please help me sort that out?
Dear Benoit can you make a video for a basic I2C arduino to arduino communication? I'm trying to doing this but it gives me back always an invalid input error.
Hi! I never did anything like that, but I take note and I'll see if I can do something. Maybe not a video, but at least an article on arduinojson.org. BTW, Arduino to Arduino communication can be a good candidate for the binary serialization I present at the beginning of the video.
Hey! Great video! Question, would you recommend Json as a method of communicating between Android and Arduino (Uart BLE Service) for a table that has 30 rows by 3 columns. plus some general settings properties, about 10. I am wanting to implement some CRC checking of the whole Json string if I do.. is this a rabbit hole? or is the right idea?
Hi! I think JSON is inappropriate for tabular information; I would use a binary format instead. If I were you, I'd try to send the JSON settings and the binary table in two different messages. As an analogy, if this was a REST API, I would use a JSON endpoint for the configuration and a BMP image (or any other binary format) endpoint for the matrix (each endpoint would have its own URL).
@@BenoitBlanchon Understood and Thank you! any tips on sending large Serial strings along with Checksum values with retry if mismatch? been looking for a best practice implementation example.
Hi Benoit, if you could help me please it would be great. I want to send data from Arduino mega to a Wemos D1 ESP8266 module with ArduinoJson but for some reasons it is not going through. I connected the TX and RX correctly on both boards and this is my code. to send: while(Serial.available()){ // Create the JSON document StaticJsonDocument doc; //getting data from sensors doc["Vin"] = Vin; doc["Iin"] = Iin; doc["Pin"] = Pin; doc["Vout"] = Vout; doc["Iout"] = Iout; doc["Pout"] = Pout; serializeJson(doc, Serial); delay(2000); } receiver: StaticJsonDocument doc; char data[] = "{\"Vin\":\"17.085\",\"Iin\":\"17.085\",\"Pin\":\"17.085\",\"Vout\":\"17.085\",\"Iout\":\"17.085\",\"Pout\":\"17.085\"}"; deserializeJson(doc, data); if (Serial.available() > 0){ DeserializationError error = deserializeJson(doc, data); if(error){ Serial.print(F(("deserializeJson() failed with code"))); Serial.println(error.c_str()); return; } //Fetching values float Vin = doc["Vin"]; float Iin = doc["Iin"]; float Pin = doc["Pin"]; float Vout = doc["Vout"]; float Iout = doc["Iout"]; float Pout = doc["Pout"];

Thanks, Rick. This does require a lot of effort; that's why I published so few videos.
generous genius
I don't remember when was the last time I spent 1h continuously watching - thank you for y our effort and presentation!

This is the best way for understanding need of JSON, XML etc
Geweldige video en zeer goed uitgelegd. Ben benieuwd naar de volgende.
This video is amazing! Extremelly clear and helpful! Thanks!
you're a very good teacher. thanks for all you've contributed. :)
Thank you very much. I wish I had time to do more videos.
Merci Benoit pour cette merveilleuse librarie... je lutilise a chaque jour... :)
Excellent presentation. Very helpful in appreciating Arduinojson's benefits and requirements.
Thanks!
Thumbs Up, New Subscriber. Excellent discussion!

Hi Benoît,
thank you very much for your absolut great json library. It helped me alot.
I liked the content and how it is delivered. I wish if you can explain it for non-arduino based platforms specifically arm Cortex series.
What a beatifull work. Thanks a lot for share.
Thanks Carlos!
tres bien fait, merci
Thanks for everything.
Thanks ,Great work - Imed ali fom Tunisia

I would applaude if you made something to work with JSON as simple as in python or JS, this is to complex.
