    you want to connect rpl border router to other machines via internet or
    just in virtual machine, you are having your rpl border router and you want
    to ping it from the machine? try using tunslip

    Thanking you,

    Hi, I'm new to contiki! [Ubuntu 16.04, x64].

    I'm trying to perform the command sudo make hello-world.upload using saved target sky. I've scoured the internet and not found a fix that has work for me yet. However, I keep getting the code below:

    using saved target 'sky'
msp430-objcopy hello-world.sky -O ihex hello-world.ihex
make IHEXFILE=hello-world.ihex sky-reset sky-upload
make[1]: Entering directory '/home/liam/contiki/examples/hello-world'
using saved target 'sky'
make -k -j 20 sky-reset-sequence

make[2]: Leaving directory '/home/liam/contiki/examples/hello-world'
make[1]: Leaving directory '/home/liam/contiki/examples/hello-world'
rm hello-world.ihex

    To my understanding, this did not run correctly and breaks the subsequent command, make login which gives me:

    using saved target 'sky'
../../tools/sky/serialdump-linux -b115200 /dev/ttyUSB1
connecting to /dev/ttyUSB1 (115200)
open: Invalid argument
../../platform/sky/Makefile.common:193: recipe for target 'login' failed
make: *** [login] Error 255

    I think this means that the mote is not properly connected somehow??

    With make motelist I receive back that my device is in /dev/ttyUSB1, which makes me think that it is properly connected.

    Could someone advise me how to fix this?
    (I apologize if this is not the correct place to ask; if it isn't please let me know where I should ask at.)

    Thank you for your time.

    Hi!

    I am having problems using "coffe-manager" with Zolertia Zoul RE-Mote hardware. I am trying to insert different files into the .bin image before its burning. Nevertheless files seem not to be available once the code is burned.

    Is there any solution or configuration?

    Thanks in advance.

      Any decent system will get the job done. You will just nned to run contiki as a virtual machine using VMware or VirtualBox. I am not sure if it ansers your question

        Thank you dear Hangkum for your reply. However I am running Contiki as a
        virtual machine using VMware, my issue is about relic implementation on
        Contiki Os.
        In other words, I would like to know how can I implement ECC on Contiki
        without using Relic toolkit any other library?
        Or if the use of library is the only path, how can I do it using Relic or
        any other library?

        Thank you

        Best Regard,

    Hi all, i'm new to contiki.I've succesfully set up an RPL Border Router and a few sky-websense, it runs as expected and I'm able to acces the websense nodes. The RPL border router finds its neighbour nodes. But, my problem is when i paused it then it doesnot find the edge router address and i need to reset the edge router to catch the address. How can i solve ma issue other than reset option.... All help will be greatly appreaciated. with regrads, Neethu V P

    I am working with TelosB node in Contiki OS.
    When I am running commands like motelist , .upload etc, the terminal is showing
    Clock Skew detected. Your build may be incomplete.

    Can anyone tell what will be the reason for this? How can i avoid clock skew?

    I try to implement thé RPL routing protocol with Contiki in order to imropve its advantages. I use the node energy metric. For that raison, I changed the following line in the file 'rpl-conf.h': #define RPL_DAG_MC RPL_DAG_MC_NONE
    by : #define RPL_DAG_MC RPL_DAG_MC_NONE
    However,the energy consumed values given are not logic. What is the problem?

    Hello everbody
    I am trying to use zoul platform found in contiki-ng (because of the memory limitation of sky mote) but this platform is not ported in Cooja. Even when I choose z1 platform ported in Cooja, it gives me error that no such platform called z1 because there is no corresponding z1 platform in contiki-ng.
    How I can handle this issue?
    Thanks.

    Hello everyone!

    I am new in contiki and I want to implement Ed25519 algorithm using Relic toolkit, I already installed contiki and and downloaded relic in relic-master and built it in contiki-2.7/MyProject/relic-target as described in https://code.google.com/archive/p/relic-toolkit/wikis/BuildInstructions.wiki

    And then I created a new folder called MyProject-relic in contiki examples folder, where I created the RelicTest1.c and the Makefile and then I added the code lines below in Makefile.include from contiki-2.7 folder:

    RELIC_SOURCE = ../../MyProject/relic-master
    RELIC_TARGET = ../../MyProject/relic-target

    CFLAGS+= -|$(RELIC_SOURCE)/include -|$(RELIC_TARGET)/include -Os
    PROJECT_LIBRARIES+= $(RELIC_TARGET)/lib/librelic_s.a

    When I go to my MyProject-relic folder and try to compile RelicTest1.c I get this error(permission):

    TARGET not defined, using target 'native'
    CC ../../core/net/rime/rimeaddr.c
    /bin/sh: 1: ../../MyProject/relic-target/include: Permission denied
    /bin/sh: 1: ../../MyProject/relic-master/include: Permission denied
    cc: error: -E or -x required when input is from standard input
    make: *** [obj_native/rimeaddr.o] Error 126

    I tried to run chmod, chown to give permission everywhere but nothing happens, I can't move forward, I really need help in order to solve my problem.

    Any help or recommandation will be highly appreciated :) :)

    Thank you

    Best Regards;
