   I'm looking for some JeeNode Diagnostics.

   I've hooked up a 2 RFM12B's(915MHz) to some RBBB's(replacing the 5V supply with the MCP1702(3.3V) that the Jeenode uses).

   I have wired things up exactly as the schematic(jlpcb-044.sch) shows. Basically, I have a DIY JeeNode, as silly as that sounds.

   I've run through the README demo, and can't quite figure out if I'm communicating with either RFM12B. Is there a simple way to tell if I've hooked everything up correctly? Some way to send a local command/response to the RFM12B?

   No errors have popped up in the serial connection. Basically, I don't want to have to tear apart the code to figure out if I've messed up some basic soldering.

   I'll admit, I haven't delved too deeply into this, but if you can save me a few hours I'd appreciate it immensely.

   Thanks,
   Chris Stotts

   Okay, I'm looking into this further.

   I've noticed that the actual Arduino I'm using won't connect to any of the RFM12B's. It'll respond to the first command I send but after that it doesn't seem to do anything.

   My serial log for the Arduino looks like this:
   > 0t
   -> 66 b
   > 0t
   > 0t
   > 0t
   > 0t

   My serial log for the RBBB with the bastardized power looks like this:
   > 0t
   -> 66 b
   > 0t
   -> 66 b
   > 0t
   -> 66 b
   > 0t
   -> 66 b

   Is there some issue with using the RFM12B on a standard Arduino?

   That first log looks fishy. You could try the raw RF12 demo on the wiki - http://wiki.jeelabs.net/p/38 - it doesn't use IRQs.

   I can't think of any issues with a standard Arduino - the RFM12B is simply an SPI device.
