400 Bad Request on CIPSEND long string
Posted: Thu Oct 01, 2015 3:30 pmHi guys,
I created a homepage that receiving data from Arduino but when i send long strings, the method that send the message fail.
The library used is
https://github.com/itead/ITEADLIB_Arduino_WeeESP8266
Code:
The string:
/Arduino/Setup?SetupData={$Identificacao$:$A109Z$,$DataInstalacao$:$01/01/2015$,$Modelo$:$Arduino Uno$}
Is working fine...i change the character "$" to double quotes on website and the data are successfully saved on database.
The Log:
When i use a small string like this:
It works.
Thanks by help
