Hello!

I just started to thinker with the esp8266 module, and it is really great! However(there always needs to be a however ofcourse) i would like to update values on my emoncms.org account.

So I tried this, following kevin darrah tips form his youtube movie: https://www.youtube.com/watch?v=qU76yWHeQuw
I can update values to thingspeak, however if I try to do this with the emoncms url, it does not do anything

How i tried uploading these values:
AT+CIPMODE=0
AT+CIPMUX=1
AT+CWJAP="X","X"
AT+CIPSTART=0,"TCP","emoncms.org",80
AT+CIPSEND=0,100
GET emoncms.org/input/post.json?json={esp:200}&apikey=API HTTP/1.1

It gives me "SEND OK", that is all... With Thingspeak I receive a log like this:

+IPD,0,551:HTTP/1.1 200 OK
Server: nginx/1.7.5

Any help would be greatly appriciated!

Hello,

with AT commands I try to send data to the server emoncms.org.
The data on the server side are not accepted. The database is left without a record.
Maybe someone can tell what's wrong here?
( To thingspeak.com server data are received correctly)

AT+CIPSTART="TCP","emoncms.org",80
CONNECT

OK
AT+CIPSEND=82
> GET /input/post.json?json={power:220}&apikey=5f95184d8fafxx***xx1e0fd9aad868 HTTP/1.0\r\nbusy s...
