Connecting to a CupCake

To follow up on yesterday’s post, I wrote some test code to request the extruder nozzle temperature from the JeeCake and send the results out over wireless. Here is the full “jeeStatus.pde” sketch:

And sure enough, it works:

You’re seeing the nozzle cool down, after heating it up via ReplicatorG. The connected JeeNode has been given node ID 19, and it’s transmitting in group 5 of the 868 MHz band, so I can simply track these incoming packets through the JeeLink which is already collecting all sorts of data anyway.

So much for the easy part – the real software will be more work!
