Exception in thread after new connection

[justinjdickow]

Tried on two different computers, a Mac with OS X 10.9.3 and ODroid with ubuntu 14.04. I'm connecting using a network device. Dev phone is a Galaxy Nexus. When I connect to the emulator the terminal logs

New connection to 0.0.0.0 from ('192.168.0.151', 53557)
Exception in thread Thread-3:
Traceback (most recent call last):

    data = self.connection.recv(1024)
error: [Errno 104] Connection reset by peer

Exception while sending data: [Errno 32] Broken pipe

On the phone I do not receive any callbacks and logcat spams

anyone out there?

@justinjdickow so not sure about your specific problem, but am able to get the simulator to work. Can you confirm the version of the openxc-enabler you are using?

[DaveMelcher]

Sorry Justin, I've been on paternity leave. I'll push this toward the top of my queue.

[DaveMelcher]

@justinjdickow When you see this, does your sim continue to function? If yes, I've replicated the issue, and I'm looking into it. (Replicated with a Mac OSX 10.9.4 and a Google Nexus 4.)

@sudipto13 the exception doesn't kill the simulator. Everything seems to continue working. Whatever's screwing up, it seems to be recovering.

[justinjdickow]

@DaveMelcher Yes, the sim continues to function - good news on this one is that I was able to get access to a Lincoln Navigator and the application I built worked as expected. Hoping to be able to obtain new vehicles soon, but working with the sim would be amazing.

Do you think it will work with a different phone?

[DaveMelcher]

It might be a network issue of some kind.

A clarification: Yesterday I replicated the error message, but the connection wasn't dropped. Everything worked just fine. Today I'm on a different network, and I can't replicate the error message. (Same computer, same phone, same software build.)

Is there anything distinctive about the wifi you're on?

[DaveMelcher]

Hey @justinjdickow , What happens if you comment out handler.start() in listen_loop(self, this_ip) ?

(It's on line 41 in my editor.) The Enabler doesn't actually send anything to the sim, I'm not sure why we're checking for it. (And I notice that the function that actually processes that is never called.)

Let me know how that goes, and if you still get consistent disconnects, please post the new error here.

It does! I use it very often for testing if a command is sent properly from my app, through the Enabler to the VI (added the feature here: https://github.com/openxc/openxc-vehicle-simulator/commit/71035ca0a2a823a01de7a000b3ac3bc0cff7515c)

[DaveMelcher]

Well shoot. (Yeah, I misread the line in simulator.py.)

@justinjdickow , Try the experiment anyway and let me know if it changes the behavior of the disconnect. I'm still having a heck of a time reliably replicating this.
