Help Getting The Arduino to Communicate to the ESP8266

By FireRaven101
- Wed Nov 11, 2015 1:07 am #33674 So, I got into arduino a few months ago. Recently I purchased the ESP8266 and a few sensors, my goal was to send the sensor info to a website (simple right?). I looked up SOOO many tutorials on it and did not really find anything useful, I dont want to flash my ESP8266 with any other software.

So now whats the problem? I can send the data to the site via the Arduino serial moniter but as soon as I try to do it via code it does not even seem to talk to the ESP module. Are there any tutorials out there that I may have missed that you could maybe link? Or if you have any idea what might be wrong it would be awesome if you could let me know.

Any help is greatly appreciated and if you need to know anything else to be able to maybe solve my issue let me know. :D

Cool – bet that’s messed with your head.

Not a problem: need more detail as to the method and problem.

A common problem – You’re not the first & won’t be the last. Things move so fast and the internet has a habit of throwing up the most popular searches even if they are out of date.

An interesting statement: most of the Arduino sketches (with a little tweaking will run on the ESP) & it’s a form of coding that you are learning.

You have come to a fantastically informed place (unlike some of the internet).
There are some amazingly informed people here who will spend hours to help others.
Answers may take a few hours to come through (up to 48).
Sometimes an answer may just be a link to another website – that’s not someone being ignorant, it’s here’s what you wanted to know.
Finally in answer to your problem, need more detail.
You are about to become involved in a world that will stimulate you brain and connect you with very informed (& friendly) people.

- Mon Nov 16, 2015 9:17 pm #34250 Thank you for the reply! You asked for more info so here you go:

After a while I found another tutorial, this one actually worked! it was able to send data to a thingspeak server and to data.sparkfun.com. But when I tried with my server it did not work.

Here is everything I sent to get it to send to thingspeak:
-AT+CIPMUX=1
-AT+CIPSTART=4,"TCP","184.106.153.149",80
-AT+CIPSEND=4,(#)
-GET /update?key=NN2TJICI823NPLZW&field1=(value)

and that works perfect. Now as soon as i try to send it to my server which is server on openshift (openshift.redhat.com). So I do the following:

-AT+CIPMUX=1
-AT+CIPSTART=4,"TCP","https://greenhouse-moun10.rhcloud.com",80
-AT+CIPSEND=4,(#)
-GET /Server/Server?command=setData&key=i3hkd7k3&data=2|3|5|6|7|8|12|No Fire|No Gas

and it goes through and gives me a SEND OK message, then it hangs for like 10 seconds and then gives me this message:
Code: Select all+IPD,4,485:HTTP/1.1 400 Bad Request

So then i tried again but changed AT+CIPSTART=4,"TCP","https://greenhouse-moun10.rhcloud.com",80 to AT+CIPSTART=4,"TCP","https://greenhouse-moun10.rhcloud.com",443, now it gives me this message:
