What needs to be done to support 6lowpan via slip via uart ?

Hi Devs,

excellent work you have done so far - congratulations !

i got my nb-iot sim card from magenta today, ten minutes after fw upgrade i was able to send out my first udp packets ! - GREAT !

as i am also experimenting with 6lowpan (contiki os), i want to connect them to my FiPy in order to query the 6lowpan nodes via CoAP and send the responses to my server via NB-IoT.

therefore the question is what needs to be done in order to add this functionality to micropython ?

on the linux side this is done with a tool called tunslip6 which bridges the 6lowpan via slip to a tun device on the pc.

i checked out pycom-micropython-sigfox from github and to my surprise i found 6lowpan and slip code in lib/lwip/src/netif.

so how can this be integrated in a custom build ?

how does the socket code know how to interface with the network devices ?

what about the AbstractNIC stuff that is documented in docs/library/network.rst ?

and how would i set this up under micropython ?

i am experienced python and embedded programmer (ported pymite a couple years ago), so no problem to get my hands dirty with this !

i think i haven't found the correct documentation, or "big picture" on how the things are connected - also not on the micropython page ... :(

so please, point me in the right direction or give me some hints so that i can bring this to life ;)

regards,
mexx.
