I just wanted to share my method of point to point communication between two computers using a Jetson TK1 and linux desktop.
Connect Jetson TK1 and Linux PC using RJ45 cable
Set ethernet IP address for both Jetson and PC
For Jetson: sudo ip ad add 10.0.0.20/24 dev eth0
For PC: sudo ip ad add 10.0.0.10/24 dev eno1
Check the assigned IP address by using “ifconfig” command in terminal We can also ensure by using the command ==>
nmap -p 80 10.0.0.20 (IP address of other device)
which returns the following in case everything is successfully connected
Starting Nmap 7.80 ( https://nmap.org ) at 2020-11-24 11:54 IST
Nmap scan report for 10.0.0.20
Host is up (0.00064s latency).
PORT STATE SERVICE
80/tcp closed http
Nmap done: 1 IP address (1 host up) scanned in 0.04 seconds
ping 0.0.0.0(IP address of other device)
- Run socket_server.py in Jetson and socket_client.py in the LINUX PC .
IN the Jetson: Connected by (‘10.0.0.10’,37240)
IN the PC: Received b’Hello , world’
NOTE: 10.0.0.20 is the IP address of Jetson and 10.0.0.10 is the IP address of PC
The TCP connection is now established
import socket HOST = '10.0.0.20' # Standard loopback interface address (localhost) PORT = 65432 # Port to listen on (non-privileged ports are > 1023) with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s: s.bind((HOST, PORT)) s.listen(5) conn, addr = s.accept() with conn: print('Connected by', addr) while True: data = conn.recv(1024) if not data: break conn.sendall(data)
import socket HOST = '10.0.0.20' # The server's hostname or IP address PORT = 65432 # The port used by the server with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s: s.connect((HOST, PORT)) s.sendall(b'Hello, world') data = s.recv(1024) print('Received', repr(data))
