BLF Write to socket - help

[lesliehallaerospace]

Hey all,

I am new to python-can and working with sockets in general, so please forgive me if this a basic issue.

The goal is to receive can data with a pi and send it over UDP to a simulink target machine. Simulink can read BLF, so I was hoping that'd be the simplest way. The BLF writer expects a file-type object, which I thought socket would work with, but it isn't compatible.

If I'm missing something obvious that'd make this work, I'd appreciate any advice - or insight on a way to format a can message so that I can actually send it on udp. Thanks!

This is the type error received

TypeError: expected str, bytes or os.PathLike object, not socket

with this code:

import os
import can
import socket

# Configure CAN connection
os.system('sudo ip link set can0 type can bitrate 500000')
os.system('sudo ifconfig can0 up')
can0 = can.interface.Bus(channel = 'can0', bustype = 'socketcan')# socketcan_native

# Configure UDP Connection
UDP_IP = "169.254.212.136"
UDP_PORT = 5005
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)  # UDP

# Configure BLF Writer
write = can.BLFWriter(sock)

try:
    while True:
        msg = can0.recv(1)
        if msg is not None:
            print(msg)
            write.on_message_received(msg)
            sock.sendto(write, (UDP_IP, UDP_PORT))

except KeyboardInterrupt:
    write.stop()
    os.system('sudo ifconfig can0 down')
