Hi, see [1]. If you want get fix it yourself, you can extend `_get` as such, that it returns the length in byte of `cc110x->radio_address` (which would be 1 in the cc110x case) as a uint16_t [2] on that opt value and provide a PR for it [3]. I think in the end that would be the faster alternative.
In general, I don't know if anyone ever tested NDN over cc110x (we usually use IEEE 802.15.4 devices), so expect more errors the way done ;-). But I think it's good that somebody finally does that work.

And i read an paper[1] from Freie Universität Berlin, in this paper, people used MSB-A2 and cc110x to running CCN-lite on RIOT.
