Hello! Thanks for the code provided! Used it on my project as a base for communication. Made a minor change to Tcp_Read() to avoid extra \r in the end.

def Tcp_Read(): a = ' ' b = '' a = s.recv(1) while a != '\r': b = b + a a = s.recv(1) return b

Thanks for sharing your work ! I've created full-duplex TCP/IP communication between two ends using threads.

s.send(D + '\r')

TypeError: a bytes-like object is required, not 'str'

Thanks for sharing your work ! I've created full-duplex TCP/IP communication between two ends using threads.

can you share it? ^^
