I am trying to get 3 values from JSON string from the server and I have my code is here : #include <ArduinoJson.h> #include <MQTT.h> char json[] = "{\"x\":\"upper\",\"y\":\"lower\",\"z\":\"gap\"}"; int refresh=1 float tempC,upperlimit=5.0,lowerlimit=2.0; StaticJsonBuffer<200> jsonbuffer; byt…

I know that, but seeing as the parsing part is working, it’s a matter of making sure the MQTT message arrives in the same format as the example. If so, then there’s no reason why that shouldn’t work either. Try comparing the data you receive from the MQTT subscription with that in the example, and …

Yes sir when I tried to send the JSON string from CLI I got my message in the terminal where I subscribed to the same topic. But the issue is those three values are not being copied to my float variables — upperlimit,lowerlimit and -int variable— refresh. This is what I am facing the problem. /…

Try reading the docs again on EEPROM and make sure the addresses and sizes involved are correct. Take care not to overlap them. [image] Jeevan_Jinnu: Yes sir when I tried to send the JSON string from CLI I got my message in the terminal where I subscribed to the same topic. Currently, you're…

I see in your code you are still not applying the hints you got a long time ago when I commented about EEPROM.write() not being the way to store float variables. I wonder why we answer questions when our answers aren't really taken into consideration. [image] To store data when not in the range …

Divide the project into small steps: figuring out what JSON is (Google is your friend here) Transmitting JSON data over MQTT, and making sure it’s formatted correctly on the receiving end. Don’t check this by subscribing on your computer, but have the Photon print it so you can compare it to somet…

[image] Jeevan_Jinnu: But one bad thing is I want to use System.reset() function whenever I update new values from CLI.So is there any ways that I can remove that System.reset() part so my code runs without resetting the device. Which one is it?
