Does startGSM() claim to succeed? - Do you get the "connected" message printed out.. Perhaps you can try calling Thingspeak.begin() only after you connect to GSM rather than before? If that doesnt...

Hi ICar, You say int Wert1 = 0; //Startwert auf 0 gesetzt google helped me saying you say start with value=0 but you never made it greater than 0 and you check if (!client.connected() &&...

You are correct. The average is using null's and lowering the expected average. If you have two devices, you might want to update two different ThingSpeak channels. If that is not possible, then MATLAB...

302 is a redirection, I don't thing thingSpeak would provide that to you directly. A wild guess is that your network is redirecting the request away from ThingSpeak. Are you able to update the...
