Development Libraries
1

Hello,
I am trying to send HTTP request from Arduino UNO + Seeed Studio Wifi Sheild

I am using the example provided by Seeed Studio
(Downloaded from: GitHub - Seeed-Studio/WiFi_Shield: WiFi library using WiFly)

But whenever I send HTTP request server gets some extra word HELLO before the http request.

HELLOGET / HTTP/1.1
Host: 192.168.43.30
Connection: close

But, I searched in my code there is nothing like HELLO

From where its coming ? Can anyone help me ?
