J-M-L:
That should be good reasons to drop this idea of using the String class that will poke holes in your memory. Build a buffer with read and you can parse with standard C functions
Thanks for reply! I have defined a buffer in the beginning, just don't know how it exactly works and with which function to read the Respons at the first step. I have also searched other ways to read data, like with cleint.read() which returns the complete response. But i don't know which c function I can use to parse the JSON string. Could you pls name some functions, I can try myself.
Thanks very much!
