Basic example using a TCP protocol. Client version. It connects to a Raspberry Pi server using a Python Script.
Dependencies: EthernetInterface mbed-rtos mbed
Fork of TCPEchoClient by
Basic program.
It connects to a remote server on a LAN running a Python script. Server send data to a spreadsheet in my google docs account.
