Where is the developer information on the bluetooth stack for the imx6ul?
Is the 4.2 Bluetooth stack part of yacto linux?

we are seeking to build a Bluetooth device to do analog to digital data acquisition
seems like the digi-connectcore-6ul-starter-kit might work, but I have not been able to find anything “developer class” at the digi site for Bluetooth development.

There is the Digi ConnectCore® for i.MX6UL Development Kit but I haven’t been able to figure why I need that vs. the starter kit, but it makes me nervous they call it a “developers kit” Do I need that?

Both kits are developement kits. Both have the same cc6ul module soldered in. cc6ul starter kit uses 76 edge-castellated pins and cc6ul SBC uses 245 LGA pins. Obviously more functionality is available on cc6ul SBC.

yes.
