Hello @vandai,

We were able to reproduce this issue and our engineers are working to solve it. Will get back to you once it is fixed.

thanks!
with your library. everything is working.
but I want to try with your own code. I just wanted to do programming.

Hi @vandai

You have some mistakes:

  1. The Content-Length header should no have break lines between the key and the value, you should be replace println by print:
...
client.print("Content-Length: ")
int length = json.measureLength();
client.println(length); ...
  1. The endpoint POST /api/v1.6/demo/Temperature/values/..... does not exists, send values to one variable using devices so it should be POST /api/v1.6/devices/demo/Temperature/values 
...
client.println("POST /api/v1.6/devices/demo/temperature/values/?token=TOKEN HTTP/1.1");
...
  1. Additionally personally add the header Connection: close for close de connection TCP and free de memory.

Let me know if you have any other problem
Gustavo.

@vandai replace your code with the next code, don’t forget to change “YOUR_TOKEN” in my code.

client.println("POST /api/v1.6/devices/demo/temperature/values/?=YOUR_TOKEN HTTP/1.1");
client.println("Host: things.ubidots.com");
client.println("Content-Type: application/json");
client.println("Connection: Close");
client.print("Content-Length: ");
int length = json.measureLength();
client.println(length); Serial.rpint("length = "); Serial.println(length);
client.println();
String out;
json.printTo(out);
client.println(out);
client.println();
while (client.available() > 0) {
    char c = client.read();
    Serial.write(c);
}

thanks you very much!
Now It’s working!
