I haven't read your code.
Anyway I can ask a question: did you try to veryfy if your "get" part works at all by printing to the serial monitor?
I don't know any details about how "get" over Wifi works. But the receiving unit is receiving "something" I guess some characters at least. So it should be possible to print the received characters to the serial monitor to analyse what character-sequence is the receiving unit really receiving.
the while(1) loop under loop itself is not nescessary
inside function taskWifi()
you have a blocking loop while(1)
are you sure that this is working?
