Problems with MQTT and Ubidots

Troubleshooting

Try these minor alterations

void callback(char* topic, byte* payload, unsigned int length) {
    char p[length + 1];
    memcpy(p, payload, length);
    p[length] = '\0';
    Serial.write(p, length);
    Serial.println(topic);
}

And I’ds low down loop() a bit or at least not push data every millisecond to Ubidots :wink:

BTW, with SOS faults the number of blinks between the SOS patterns is important info for troubleshooting.

@jade7272, when posting code, wrap it in a set of these for better formatting

 ```cpp
 // your code here

I have corrected that for you. And for further hints on the subject have a look here
