hexfactory 0:d4bf65e1d0d7 6 This example
hexfactory 0:d4bf65e1d0d7 7 - connects to a wifi network (SSID & PWD to set in mbed_app.json)
hexfactory 0:d4bf65e1d0d7 8 - Connects to a TCP server (set the address in RemoteIP)
hexfactory 0:d4bf65e1d0d7 9 - Sends "Hello" to the server when data is received
hexfactory 0:d4bf65e1d0d7 10
hexfactory 0:d4bf65e1d0d7 11 This example uses SPI3 ( PE_0 PC_10 PC_12 PC_11), wifi_wakeup pin (PB_13),
