Question

I saw the example give on the webclient. it is using http get instead of post. i want to the arduino uno + wizfi shield to send data to the carriots. Can i get some guide on http post for webclient?

There is HTTP-PUT example as below. Even though it’s not HTTP-POST, I believe that you can refer it. [url]https://github.com/Wiznet/Arduino_WizFi250/blob/master/Software/WizFi250/Examples/WizFi250XivelyClient/WizFi250XivelyClient.ino[/url]

Hi, This is the example for webclient using http post. “Ubidots.com” offer this example. [url]Connect an Arduino UNO + WIZnet WizFi250 to Ubidots over HTTP | Ubidots Help Center But, source code was little modified. //------------------------------------------------------------------------------------------------ /* Simple example using WizFi device This example was made using an example of the original library and was modified to work with tje Ubidots platform.
