Thanks chunlinhan for your effort.
I modified chunlinhan's library to fit into Arduino Uno. There are several limitations because of the limited memory and UART port of Uno.
- AltSoftSerial was used and RX buffer may be too small.
- Only web client functionality was tried. Even scan functionality was removed because Scan reserves 10 entries in the memory (huge for Uno)
- For unknown reason mySerial.begin should be called from the main sketch file.
