Issue with ESP-01 & Terminal & pushingbox API
Posted: Wed Feb 08, 2017 4:32 pmHello guys, after 3 days of struggling I decided to ask for some help.
I have my ESP-01 connected to a USB-to-TTL converter and I send the commands through Terminal (by bray).
What I want to do is to put the esp-01 into client mode then connect to pushingbox and finally send a GET request with my deviceID (API) to pushingbox. Then a notification will come to my android through my newtifry account.
I have tested the pushingbox scenarios from my PC and newtifry notifications comes to my android as expected.
Also when I type the url with my deviceID ( http://api.pushingbox.com/pushingbox?de ... xxxxxxxxxx ) in the address bar it works fine.
BUT when I try to do the same thing with esp-01, when I send the get request i receive a... 400 Bad request (Your browser sent an invalid request). I changed the GET request format several times but nothing works.
I believe that the GET request I send is incomplete somehow but I cannot figure out what is missing.
Note: Terminal doesn't recognize \r and \n as single byte characters ( so \r\n = 4 bytes ===> one for each character \ r \ n). So the URL string I send is the number of URL characters + 4 bytes for every \r\n in the string.
For example if the URL string is 88 characters (bytes) long with \r\n\r\n in the end I add 8 characters.
Below I display the exact sequence of commands I send everytime and also the different versions of the GET request I have tried to send so far with no success.
Thank you for your time and help
