Android - doesn't work with python3-zeroconf #26

Closed SrMouraSilva closed 7 years ago

SrMouraSilva commented 7 years ago

Python zeroconf is a Pure Python Multicast DNS Service Discovery Library (Bonjour/Avahi compatible) https://pypi.python.org/pypi/zeroconf

cordova-plugin-zeroconf can't discover (watch) a Python zeroconf service, but the reverse works.

Sorry for the description of the error, I do not know what the cause of it would be. If you can quote how can I help ...

Can you show how you call wsserver.watch? And how you register your service in Python? Thanks

Watch: https://github.com/PedalPi/Apk/blob/1fedfdd2223a7c18bd48dba0b9303e8f7cce4962/src/pages/configurations/configurations.ts#L43

Python service https://github.com/PedalPi/WebService/blob/b63bfc916948a2fb11f822751beb1e7c90677c94/zeroconf/server.py#L24

Observation:

The cordova-plugin-zeroconf works with my dlink router
The cordova-plugin-zeroconf works with python pybonjour3 with avahi (apt-get install libavahi-compat-libdnssd1)

Are you saying all is fine with this other python library, i.e. pybonjour3?

Looks to me that Python side you're registering your service on a loopback address socket.inet_aton("127.0.0.1")? Could you try on another interface and one that supports multicast instead?

Yes

This really does not make much sense. I followed the example and did not mind.

Could you try on another interface and one that supports multicast instead?

I tested in a PC with cable and in a notebook with wi-fi.

I will try again with an not IP loopback

Thanks

Let us know the result of you last try and then close this issue please as the problem is not with this plugin.

Hello, I'm sorry for the delay in replying.

I did some more tests and found that the problem was possibly in the configuration. The host in python-zeroconf must be the IP of the machine on the network where the other devices will be connected. So the other devices will be able to locate the machine.
