Connecting Arduino to network…
DHCP Failed, reset Arduino to try again
Connection to ThingSpeak failed (1)
Connection to ThingSpeak failed (2)
pleade help me.

I had a question about uploading string to the channel. I have a sensor that gives me two data every second. And I want to upload these data to my thingspeak channel every minute that is 120 data in total. I put them in a long string like 2,4,5,1,3,1,…….
Can thingspeak support this kind of data format? Most of application on thingspeak only upload one single point of data every time. How to update a array of data in one time?
Thanks a lot !

I have an Arduino Mega with ethernet shield W5500 processor with.
Everything works properly, but after about an hour, telling me error in the connection to the site. To make it work I have to power cycle.
I also tried it with several other ethernet shields (W5100, W5200), but the result and the same.
Possible that these ethernet shield do not work all the time and always give problems? If so, it would be only of disappointments.
Someone managed to make it all work?

Please try the official library and see if that works for you.
Here is the forum post for more information;

You can set up the new ThingSpeak Communication Library for Arduino in about 60 seconds from within the Arduino IDE, and try out the examples right away! You can read and write with just 1 line of code!

Arduino: 1.6.5 (Windows 7), Board: “Arduino/Genuino Uno”
thingspeak01:35: error: The Client class has been renamed EthernetClient.
As of Arduino 1.0, the Client class in the Ethernet library has been renamed to EthernetClient.
Any help appreciated

However, I think it is better to update two seperate Thingspeak channels. I added the following lines to the sketch:
String Key1 = “…”;
String Key2 = “…”;
…
// update channel 1
writeAPIKey = Key1;
updateThingSpeak(…);
client.stop();
// update channel 2
writeAPIKey = Key2;
updateThingSpeak(…);
Though this seems to work, I don’t know if it is the best approach. And it is only the update response from the second channel printed to the Serial Monitor.
Any suggestions on this?
