CCS/MSP432E401Y: Create TCP Connection between MSP432E401Y(Client) and PC(Server)

Part Number: MSP432E401Y

Tool/software: Code Composer Studio

Hello,

I want my MSP432E401Y to work as a client and connect to the PC. In the example tcpecho, although a connection is established with the PC, the microcontroller waits (accept ()) for a request. I want the microcontroller to send the connection request (connect ()).

I did the following but unfortunately it does not work. what am I doing wrong?

regards,

Fares
