NMEA server doesn't receive sentences

[psj6]

Hello, I'm trying to send over UDP on localhost sentences of NMEA, but in the debug point doesn't receive anything.

It stays here giving -1

I tried everything, from changing ports, firewall, starting server first or sending later, resending other sentences and nothing.

Also I tried the NMEA simulator 1.5.0 and doesn't work too, so I think it's something that the program has that I don't know.

Maybe it's some problem with the asio?

Wireshark receives the packet so I'm sending correctly to 127.0.0.1 in the correct port 10111

On branch master... maybe it's any issue here?

A bit of a shot in the dark here since I can't reproduce the problem on my end, but can you see if #55 fixes your issue?

Hello @antoine0183 , thanks for the PR, it doesn't work for me. Have you got any code on Python, Java or another language that I can use to test it out? I tried to use pyenet (https://github.com/piqueserver/pyenet) but I can't make it work.

I can receive data from UDP in my App but I can't send, the debug point nread > 0 doesn't work. Maybe I need to switch on the sender and after start the bridge simulator? I don't know.

Maybe it's the bridge simulator getting the port and locking it on localhost? I didn't try over network... Maybe it's an issue of my computer. I dont't know...

Hello @antoine0183 , I tried weeks later and it works. It's perfect and it receives the sentences perfectly.

I was trying with pyenet and maybe created some issue with the ports in my PC and didn't try again.

The code that works for me (in debug mode, maybe the sentence it's not correct) is:

import socket, time

ip = '127.0.0.1'
port = 10111

message = "$--RPM,a,odd,50,50.0,A*ff"

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

while True:
    sock.sendto(message.encode('utf-8'), (ip, port))
    print("sent message:", message.encode('utf-8'))
    time.sleep(1)

sock.close()

What's new with your code? Windows can be the issue
