Sphero

An Elixir library for interacting with a Sphero device that's connected via bluetooth. Brought to you by Josh Adams, purveyor of Elixir Sips.

Usage

{:ok, s} = Sphero.Client.start(device)
Sphero.Client.ping(s) #=> Sends an 0x01 0x00

Or to see an example:

mix run examples/square.exs

Development

To get some sockets to play with without worrying about the sphero, use socat:

socat -d -d pty,raw,echo=0,nonblock=1 pty,raw,echo=0,nonblock=1

Then connect to one of those sockets in screen with:

screen /dev/pts/7 115200,8,N,1

And open the other with the sphero client. Send it commands. See them come through...

Debugging

To see what's being written to a given socket, you can do the following with socat:

socat -d -d -u pty,raw,echo=0,nonblock=1 OPEN:/tmp/foo.data,create,append    

Now any bytes written into that socket will end up in the new file.

TODO

I don't yet parse any of the messages coming FROM the sphero, but that's not relevant to my Erlang Factory 2014 talk, so it won't come for a bit :) Pull Requests welcome :)
