I didn't really understand the box. Open Mesh makes and supports the ideal device that you can't use. It's only one item to add and reduces the connections at the radio. A great idea, but can't be used.
It's possible to use the extra wires in the cable with the work around adapters posted above. I've used similar ones (
mine come from Adafruit for $5.95+shipping with good success in non-mobile applications. But only needing one end would be good.
Any ideas why the GDC decided to not allow the Open Mesh device?
