jruby - artoo connect serial not listening on port

[PragTob]

Hi there,

thanks for making artoo. I got a sphero and today I wanted to play with it a bit from ruby. I got jruby-1.7.6 and I tried following the guide but things didn't work as they should.

I'm running Linux Mint Debian Edition latest Update Pack.

Basically it seems to me that the artoo connect serial command does not actually result in something listening on that port. I'll give you my basic shell output:

tobi@speedy:~$ cd github/shoes-artoo/
tobi@speedy:~/github/shoes-artoo$ artoo connect scan
         run  hcitool scan from "."

    68:86:E7:00:3D:BE   Sphero-OYP
tobi@speedy:~/github/shoes-artoo$ artoo connect bind 68:86:E7:00:3D:BE Sphero-OYP
         run  sudo rfcomm -i hci0 bind /dev/rfcomm0 68:86:E7:00:3D:BE 1 from "."
[sudo] password for tobi: 
         run  sudo ln -s /dev/rfcomm0 /dev/Sphero-OYP from "."
tobi@speedy:~/github/shoes-artoo$ artoo connect serial Sphero-OYP 8023
         run  sudo chmod a+rw /dev/Sphero-OYP from "."

Exception: java.lang.ThreadDeath thrown from the UncaughtExceptionHandler in thread "Thread-17"
         run  socat -d -d FILE:/dev/Sphero-OYP,nonblock,raw,b57600,echo=0 TCP-LISTEN:8023,fork from "."
tobi@speedy:~/github/shoes-artoo$ netstat -a | grep 8023
tobi@speedy:~/github/shoes-artoo$ ruby try.rb

(snipppp)

When I rerun artoo connect serial Sphero-OYP 8023 it just does:

tobi@speedy:~/github/shoes-artoo$ artoo connect serial Sphero-OYP 8023
         run  sudo chmod a+rw /dev/Sphero-OYP from "."
         run  socat -d -d FILE:/dev/Sphero-OYP,nonblock,raw,b57600,echo=0 TCP-LISTEN:8023,fork from "."

But yeah. still no effect.

Ah yes, try.rb is the sample from the guide e.g. the connection code is:

require 'artoo'

connection :sphero, :adaptor => :sphero, :port => '127.0.0.1:8023'
device :sphero, :driver => :sphero

So yes, 8023 is the right port :-)

Help? =D

Cheers, Tobi

PS: Oh btw. I got sphero 2.0

@PragTob whats the output of

$ socat -V

[PragTob]

Output is this:

Is socat a dependecy that i missed? Needed to install that package.

Thanks for the help! Tobi

[PragTob]

Yes it seems that socat was a dependency, sample works now, thanks.

That dependency should absolutely be mentioned in the docs and the failure message maybe could be improved at one point.

Is the website open source e.g. can I submit a PR? I dunno the source so improving the error message seems harder to do for me, but if you give me a pointer I'd also love to do this.

Thanks for your help, Tobi
