yes. actually. They accepted us. Our boards were already made and the chip
didn't come in time to change them. Our first app is on Android.

We didn't use LE in the past designs as it didn't have the bandwidth to let
images and animations through the wireless pipeline. However, I'm open to
new ideas and Broadcom's chip sounds interesting, can have a looky see.
Thanks - A
