I have no association with Nordic, but I'm developing a product using them. The E1 has an integrated 8051 in a 36 pin chip - a lovely clean solution with pcb track antenna, no licencing required.

Nordic doesn't have a discussion group & suggested I start one - so I have.

If you are looking to use this chip, you might like to join to give it a kick along. At this point, I have posted to the discussion forum the correspondence I have had with Nordic on various issues. It's here:
