The order of operations are described in that github wiki link, but I remember using linux-quic instead of linux-yocto. We followed the instructions here
Building Custom Yocto Image to build the yocto image and simply enabled Bluetooth driver support from the menuconfig.
For instructions on using swicwe we followed this, https://source.sierrawireless.com/resources/airprime/software/swicwe/
So our steps were
- Follow the instructions in https://github.com/mangOH/mangOH/wiki/Bluetooth-WL18xx-driver-for-mangOH and Building Custom Yocto Image to build our yocto image.
- Download compatible modem firmware and bootloader from https://source.sierrawireless.com for our WP module.
- Build our applications into a legato image.
- Stich all of the above into a single image using swicwe https://source.sierrawireless.com/resources/airprime/software/swicwe/
- Flash using swiflash https://source.sierrawireless.com/resources/airprime/software/swiflash/
We used a native Linux box as we couldn’t get some of these tools working on a VM.
