Hello,

I’m currently working on a project using a WP7607-1 module and we’re integrating the WL1835MOD to our board.

I’m trying to use [yocto\_wp76\_wp77\_meta-bluetooth](https://github.com/dpfrey/yocto_wp76_wp77_meta-bluetooth) to add bluetooth drivers to the wp76xx linux distribution but the compilation fails at the end.

The distribution I’m using is the latest available for wp76xx found on this page: [wp76xx-firmware-latest-release-components](https://source.sierrawireless.com/resources/airprime/software/wp76xx/wp76xx-firmware-latest-release-components/).

I can compile it without adding the meta-bluetooth layer.

Error is the following:

ERROR: linux-quic-3.18.44-r1 do\_compile\_kernelmodules: oe\_runmake failed

Any idea of what could be going wrong? Did somebody manage to use this layer with latest linux sources for wp76xx?

Thanks in advance,
