+Hyperterminal settings: 115200 bauds, 8-bit data, no parity
+
+This example
+ - connects to a wifi network (SSID & PWD to set in mbed_app.json)
+ - Connects to a TCP server (set the address in RemoteIP)
+ - Sends "Hello" to the server when data is received
+
+This example uses SPI3 ( PE_0 PC_10 PC_12 PC_11), wifi_wakeup pin (PB_13),
+wifi_dataready pin (PE_1), wifi reset pin (PE_8)
