ESP8266 Community Forum

- Thu Jan 21, 2016 7:12 pm #39401 I have successfully managed to set up my esp8266 and it is connected to my wifi, however I am having difficulty successfully posting data to the sparkfun server.

I'm just using the serial monitor on the arduino IDE to manually send the following commands, and it replies to each : see attached screenshot. Once I have achieved success I would make an arduino programme. I am just unable to get past this point.

Code: Select all//set multiple connections
AT+CIPMUX=1

//open tcp connection
AT+CIPSTART=4,"TCP","54.86.132.254",80

//send number of characters characters
AT+CIPSEND=4,95

//push data
GET /input/<publickey>?private_key=<privatekey>&flow=30.00&temp=45.00 HTTP/1.1

//close connection
AT+CIPCLOSE=4

Now, I have spent a couple of days trying different things but my sparkfun stream still has nothing in it from my arduino.

Please help thanks,

Set the number of characters to 151,

Sent the below:
GET /input/XXXXXXXXXXXXX?private_key=XXXXXXXXXXX&flow=60.00&temp=15.00 HTTP/1.1\r\nHost: data.sparkfun.com\r\nConnection: close\r\n

Hit the serial monitor/console send button several times until the following displayed :
