Hi,
I'm using a Arduino Mega with a Ethernet Shield. The last 10 months it worked great. But this month data is missing in the graphs. I've reset-ed the Arduino and updated the ThingSpeak library to 1.2.1. and now it only sends a very limited number of data points and then stops.
Is there a method/command to put a read-back in the Arduino code to see on the Serial.plotter how ThingSpeak response to my write action?
(I have put the data I'm sending to ThingSpeak on the Serial.plotter and it seems the right values).
