I am using iteaduino nano with esp8266 (esp-01) using esp8266 library from ubidots and I got http 400 while submitting to ubidots. beside http error 400 it also display {"detail": "JSON parse error - Expecting property name enclosed in double quotes: line 1 column 74 (char 73)"}

I am able to display the data sent to ubidots, this is the data :
[{"variable": "5763276b7625426909349ce2", "value":"28.10000", "context":{, }}, {"variable": "5763277376254269b8a5c72f", "value":"84.80000", "context":{, }}]

this is the whole response that display in serial console :

Hi @nugrahadi usually if you’re not using the context key, the correct payload should be:

[{"variable": "5763276b7625426909349ce2", "value":"28.10000"}, {"variable": "5763277376254269b8a5c72f", "value":"84.80000"}]

We’ll verify if the problem lies in Ubidots’ library and get back to you. Thanks!

Could you go to source tab and try to find if there is a data source named ESP8266 ?

11

yes there is data source named esp8266. is that auto generate?

12

@nugrahadi
Yeah i update that library. I change something, now you can save variables in Ubidots, using just the name of variable

client.add("variable_name", value);

But i will add the old method to maintain the compatibility. do you like the new method or you want the old method?
Whatever the response, I will add the old method.

13

well, I prefer the old method. But I’ll try to use the new method for a while.

Thank you

14

ok than you for your answer. I think that today i will post the old method too, then i will write you to let you know.
