adustm | 0:c301ccc87f5b | 6 | This example |
adustm | 0:c301ccc87f5b | 7 | - connects to a wifi network (SSID & PWD to set in mbed_app.json) |
adustm | 2:9a54ede37c7e | 8 | - Connects to a TCP server (set the address in RemoteIP) |
adustm | 2:9a54ede37c7e | 9 | - Sends "Hello" to the server when data is received |
