import socket
import numpy as np
from connections.socket_utils import send_text, send_image

sk = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sk.connect(("localhost", 5000))

# send text with length with format: {lenth}:text:{your_text}
# ex client send "Hello", server revcieve "5:text:Hello"
msg = time.strftime("Client sent %H:%M:%S\n")
send_text(sk, msg)

# send array with length with format: {lenth}:image:{your_array_encode}
mat = np.random.radnint(0, 256, (640, 480, 3))
send_image(sk, mat)

Logger
