Re: [riot-devel] Border Router and SLIP

2016-01-19 Thread Cenk Gündogan

Hello Francisco,

You do not need RPL for your setup:

* Start your border router application and tunslip6 (e.g. beef::1/64)
* configure beef::2/64 on interface 6 at the border router and
  add beef::1 to the neighbor cache on interface 6
  (these steps are outlined in the border router README)
* add abcd::1 to interface 5 of the border router
* connected 6lr applications (e.g. the microcoap example) should receive
  a RA that contains information about the prefix (abcd::/64) and
  they configure a global ipv6 address automatically
* now you should be able to do a ping6 from/to your microcoap examples.

You might however follow the discussion in [1], because there might be 
problems

with IPHC/NHC for this setup.

PS: You can use ethos [2] to reduce the number of UARTs for your border 
router.

Hello RIOTers!

I'm trying to make a small network with 3 samr21 boards, one as a border
router connected to my PC via SLIP (using the example
gnrc_border_router), and the other two as CoAP servers (using
microcoap_server example). My goal is to reach both boards from my PC
using Firefox with Copper.

For now, I succeeded creating a RPL network with the BR and the two
boards (ping6 is working on all boards, the BR as the root). I followed
the steps in [1] to configure RPL and [2] for the SLIP interface. I also
added a route:

fibroute add :: via  dev 6

on the BR.

Afterwards, I connected the SLIP interface through an USB-Serial cable
which is connected directly to the 2nd UART on the samr21 board, but I
cannot make work the SLIP interface with tunslip6 (I cannot ping any
board from my PC, even the BR).

I'm thinking about modify the slip implementation to use only the main
UART interface, but as far as I know some people is already working on
this.

So, my questions are: is there a tutorial or step that I'm missing? Is
actually possible to do what I want?

Thanks in advance!

Cheers!

Francisco.

Re: [riot-devel] Contiki as a RIOT thread

2016-01-19 Thread Cédric Adjih
Hi, 

That's an excellent idea! 

Also as you are looking for implementation pointers, 
maybe it is worthwhile to look at what the company HiKoB did: 

- for their product, they modified Contiki to run on top of FreeRTOS 

- a derived version is available here: https://github.com/iot-lab/contiki 
( shameless plug: ported to M3 nodes of http://iot-lab.info ) 

cheers,

Re: [riot-devel] Contiki as a RIOT thread

2016-01-19 Thread Martine Lenders
Hi,
Just on the subject on uIP: I'm currently working on an emb6 port (in
parallel to the lwIP port), which is a proto-thread-less fork of uIP. But
as discussed in [1] and by the advantages you have given additionally, it
would definitely make sense to run Contiki in RIOT.

Cheers,
Martine

[riot-devel] Contiki as a RIOT thread

2016-01-19 Thread Joakim Nohlgård
Many legacy applications are built on Contiki, and many papers on IoT
are written around tests done on Contiki. Contiki also has a quite
large community who work with applications on the platform.

Because of this it would be useful to have a way of running Contiki
applications and projects under RIOT with minimal porting effort.

Contiki is effectively running on the hardware as a single thread with
some preprocessor magic to make the protothread functions behave as if
they are cooperatively multitasked threads, which makes it quite
doable to run Contiki as a subprocess/thread inside a RIOT system.

It would also be possible to use Contiki's uIP as an alternative
network stack to gnrc, just like the lwIP port in
https://github.com/RIOT-OS/RIOT/pull/3551.

Some important points to know about Contiki from a RIOT perspective:
- Tick-based (platform specific, but usually 64 Hz)
- Cooperative scheduling of protothreads, which are not "full"
threads, but more light weight, no individual stacks etc.
- There is a native port which runs on Linux, just like RIOT native.
- Contiki's network stack is somewhat modularised to allow for
swapping radio devices, mac layer etc.
- No real time guarantees, as far as I know.

A starting point might be to use the native platform and to apply an
adaptation layer to allow netdev2 devices to be used as output by
Contiki's uIP stack. Another way would be to write an adaptation layer
between Contiki uIP and RIOT conn, to use gnrc instead of uIP.

Benefits from this would be that we could for example use 6TSCH in uIP
on RIOT and/or the lwm2m and IPSO smart object implementation from
Contiki. Since RIOT is, in my opinion, way superior with regards to
hardware support and its hardware abstraction layers, and with many
drivers for common sensor devices already implemented it might attract
some Contiki users to try RIOT for their IoT projects.

I would like to hear any ideas and opinions on this list on how to
effectively implement this.

Best regards,
Joakim
