10 years ago Hello forum.
I made some progress on this issue, but still can't start testing communications.
This is the progress done:
* On the host side, want to use Jennisense/contiki-jn51xx/tools/tunslip6.cThe tunslip6.c tool compiles and works fine on the PC host:
$ cd Jennisense/contiki-jn51xx/tools
$ make tunslip6
$ sudo ./tunslip6 -B 115200 -s /dev/ttyUSB0 -v5 aaaa::1/6
* On the mote side, want to use examples/ipv6/rpl-border-routerThe rpl-border-router doesn't compile fine. This is the compilation log:

Can somebody help this this issue, please?
Thank you in advance.
Hello.
I want to test IPv6 communications between my PC host and a Jennic JN5148 mote on the 6LowPAN network. I want to use a SLIP channel to exchange (send/receive) information between mote and host.
On host (PC) side, I have found these two examples on Jennisense:
What is the best option to use? tun? tap? Or once setup, it doesn't matter?
In file: Jennisense/applications/ethbridge/README (and also in some old posts published on the forum), this link is pointed:
Supposedly, it points to a document explaining more information on slip bridging. But that link is broken. I would like to take a look, to learn more about this before asking stupid questions. I have searched on Google, but it seems not being available at all. Does some of you know a different source to find it?
Related with mote side, what Contiki application should be loaded on the mote, to be able to exchange information with my host?
Reading README file applications/ethbridge/README, it seems tapslip6.c should be used on mote side, and slipbridge.c on host side. But there are so many alternatives, that I'm not sure how to start with this...
Any help on this will be very welcome!
Thank you in advance!!
Best regards, -- Ivan
