@lupyuen @RIOT_OS A first version has been released now at <https://github.com/bouffalolab/bl_iot_sdk/tree/master/components/network/lmac154>.
As feared it is just a header file and compiled blob. On the upside, the Apache license applies, so decompilation may be fair game for reverse engineering.
That should make a nutcracker challenge v2 doable -- but frankly, I rather stick with vendors that publish documentation or at least commented source.
@chrysn Interesting ... Wonder if the Nutcracker folks are aware of this
@lupyuen Only if there is documentation of the radio, or a freely usable implementation. Unless the vendor takes a less #FLOSS-hostile stance there, I don't see it happen.
For comparison, nRF5x has become very popular around @RIOT_OS, while EFR32 which we had high hopes for 5 years ago is still niche and unusable.
