Problem with Jeenode V4

(Just to start with a bit of background - I've got 8 Jeenodes so far - 4 of these hand soldered without any real problems except for turning the radio the wrong way round for the first one)

I received my first 2 Jeenode V4's a couple of days ago - and soldered them together, and started them up.

Both displayed the same behaviour - where the prompt for the Demo sketch cam up as one line, with no further activity.

I have spent a bit of time trying to find out why - including using a magnifying glass to check my soldering etc.

In the end I had to start software debugging - and it all ended up with these lines in RF12.cpp

" // wait until RFM12B is out of power-up reset, this takes several *seconds*

   Serial.println("Ready for rf12_xfer 3");

   rf12_xfer(RF_TXREG_WRITE); // in case we're still in OOK mode

   Serial.println("Ready for digitalread");

// while (digitalRead(RFM_IRQ) == 0)

// rf12_xfer(0x0000);

   Serial.println("Finished digitalread");"

As you can see between my debug statements I ended up with commenting out the "while" loop waiting for the RFM_IRQ pin.

With this line commented out both boards work as expected, and my ROOMS sketch works ok.

Running the DEMO sketch I have set the ID's correctly, and receive packets from the other active nodes in the house.

Any ideas on what went wrong?
