Hi @wpardis
About Mote to Ethernet Adapter: if I understand correctly BM works on top of Ethernet then in theory I think Mote to Ethernet adapter should not even be needed. In theory it should be enough to have 10Base-T1L to “regular Ethernet” adapter, like i.e. EVAL-ADIN1100 board which @spiderkeys was using here Bristlemouth Native Linux Support - A work in progress! or even the one I’ve made 10Base-T1L RPi header with power over data line extension. In practice however I think some version of native Linux support for BM would be needed in both cases.
On the other hand because both are basically Ethernet I think it should be possible to use both BM and non-BM devices.
