Unable to use feed from serial port (ttyS0) #11

Open yanniedog opened 3 years ago

yanniedog commented 3 years ago

Hi Mikey,

I get this error when trying to use the ttyS0 serial port for AIS data:

pi@SmoothIsland:~ $ sudo docker run --rm -i -t -p 8888:8000 -e DATA_SOURCES=ais-serial://dev/ttyS0?baud=38400 mik3y/airdash yarn run v1.22.5 $ WEBPACK_TARGET=prod node server/server.js info: Server starting ... info: config: {"listenPort":8000} info: Starting server ... Error: Failed to add data source ais-serial://dev/ttyS0?baud=38400: Error: Unsupported protocol "ais-serial:"

Hey @yanniedog! Okay, this will probably take us a few iterations, but I think we can get this solved.

Your command looks right, the issue here is the docker image has not been updated. I'm checking why, and it looks like this is because the automatic build failed - so there's no fresher one for you. Let me see if I can get this fixed, it may take about 20-30 minutes. Stand by!

@yanniedog okay, please try updating the docker image, and running again.

You can update the image with this command:

docker pull mik3y/airdash

@mik3y thanks very much. Please see below:

Hm! That error suggests you might already have it (or something) running on port 8888.

Try a docker ps to see what's running. You should then be able to use docker stop or docker kill to shut down an existing version of airdash, if one is running.

Thanks mik3y, that fixed it. Now, Docker loads correctly, but unfortunately it still doesn't show ships on the map:

Whoops! Sorry I missed your comment here.

Could you try enabling debug logs? I am not sure if it will add what we need.. but it could.

Should be something like adding the following to the docker run command:

-e DEBUG='airdash:*'
mik3y commented 3 years ago

Hey @yanniedog - I thought of another issue that could be affecting this. Do you run some other software that reads from the AIS device at port /dev/ttyS0? I believe only one program can read from that at a time, so if something other than airdash is running, that could be the problem.

yanniedog commented 3 years ago

The issue I'm really, really struggling with is the basic Docker / Docker-compose commands. I don't know how to do the fundamental basics of Docker, and don't have any idea what I'm doing when it comes to docker/docker-compose. It's preventing me from participating

mik3y commented 3 years ago

Understood! Sorry about that - I remember there is indeed a bit of a learning curve. And probably doubly so when you aren't sure whether the software itself is buggy (as could definitely be the case here)..

Would you be up for letting me ssh in and look things over? I can probably troubleshoot things quickly that way. No worries if not - I understand not wanting to trust a random internet stranger with computer access :-)
