Access to remote sky mote about 6lbr HOT 5 CLOSED

Hello,
If you want to collect data from a remote sky mote without running a webserver on that mote, the easiest alternative would be to program the node to send its data periodically to a UDP server. You would run this UDP server on your border router, or better, on a host on the IPv6 side (local network, cloud, whatever...). Note that this changes the traffic pattern requirements from general bidirectional connection to a pure-collect scenario.

For the client side, you can check out examples/ipv6/rpl-udp/, in which you configure the IP and port of the UDP server. As for the UDP server, it can be an application of your own which can be very light if it's just a python script or ncat, etc.

Hello Sebastien!

Thank you very much for your answers! I am aware about the examples from
Contiki tree and I think I start to understand them. What I would really
appreciate (and still hope to find) is some more documentation about 6lbr
and how it is organized. For now I am trying to get this by reading the
sources, but I hope to find something that will save me some time.

Thanks again for your time!

Best regards,

Calin

Reading the sources and documentation of 6LBR will give you some insight in how it functions, but you will not find answers there related to how you can retrieve information from your sensors as this is independant. 6LBR enables end-to-end IPv6 connectivity between an IPv6/NDP network and a 6LoWPAN/RPL network. What you do above 6LBR is up to you: run a webserver on a mote to send http/coap requests to it, or implement a UDP client to allow it to post measurements itself.

On a brighter side, we are looking into including CoAP-related examples above 6LBR in release 2.0, which could certainly help your understanding. We're just ony finalising 1.1 though, 2.0 is sometime during the summer.

I'm sure other people can contribute to this question, so feel free to continue this discussion on 6lbr-dev mailing list: http://lists.cetic.be/cgi-bin/mailman/listinfo/6lbr-dev

Best regards,
Sébastien

Thanks again! :-)

I fully understand the relationship between 6lbr as a connectivity
framework and the applications running above it. What I am looking for now
is to get a picture of how to run it one on top of the other. Being on the
beginning I started by learning about 6lbr and how it can be used. Then it
will come the motes part (where also I have a rought understanding).

I will follow your suggestion and move the topic on the mail list.

Best regards,

Calin

P.S. Can you give me an idea when 1.1 will be available? There is a
connectivity problem that does not really have a workaround (please see
6lbr issue #3). Thanks!

Just wanted to let you know there's a much smoother integration of coap in the upcoming release.
Closing this since it's been a while and no pending issue.

feel free to re-open of course ;)
