Any news on this?
I would love to use the SparqEE Cell on BeagleBone Black, the new BeagleBone Green Wireless or any BBB-compatible board.
The NimbeLink Skywire cape (see http://elinux.org/Nimbelink:SkywireCape
) seems to be a valid alternative, but it seems also to be quite expensive.
I'm going to try M2M solutions from Yantrr (see https://yantrr.co/m2m-cape-for-beaglebone
), but they are not going to have a distributor, so ordering their goods is a pain.
Yantrr also developed VIBE, a BBB variant with USB port extended to powered hub to eliminate USB device power down issues (maybe you should also consider this when working on a cape for SparqEE).
