Hi folks,

I need to send receive plain TCP data packets (one byte payload only) to a given IP at a given port.

I have found the UDP library and the corresponding classes, but nothing similar to TCP.
udp.beginPacket(address, 123);
udp.write(packetBuffer, NTP_PACKET_SIZE);
udp.endPacket();

Could somebody help me how to code the same with TCP?
Thank you.

Simply take that example and rip off the serial port stuff, you will end up with plain TCP server.
