#74471 Hi,
As part of my project, I'm uploading data to the Thingspek IOT platform. To test the wifi module and to get an idea how the whole thing works. I connected ESP8266 with a USB TTL Serial. I used Serial Prompt in Linux to send AT commands. Module gave a response to every command and connected it to a wifi network. Then I tried to update field value of Thingspeak.
1.AT+CIPMUX=0
2. AT+CIPSTART = "TCP","www.thingspeak.com",80
2.AT+CIPSEND=74

got reply as

then I pasted the following link
GET https://api.thingspeak.com/update?api_k ... &field1=25\r\n

SEND OK

But the Thingspeak filed values were not updated. Anyone have any idea about this.

Thanks
