Hello,

i am having packet lost problems while communicating 2 motes (dtls-client and dtls-server).
It only happens when the DTLS handshake try to send 3 packets ( 120 bytes each) in a aproximately 150 ms between the first and the last one.
The sender(dtls-client) sends all properly ( wireshark detects it too, properly), but the receiver(dtls-server) just receive the first one, or the second one too, but never all of them. I think that is it not problem of buffer size or queuebuf, since the defines are the following:

define QUEUEBUF_CONF_NUM 14

define UIP_CONF_BUFFER_SIZE 2560

Since i think that the problem is caused by the lack of the delay between sends, I would like to make a delay separation between the packets to give to the receiver some extra time to receive all properly, but the three packets are sent from a function, not directly from the main of a process, so i am only able to make some _delay_loop_2(50000); but this doesnt work because ( i think) its stops all the retransmission by making the CPU stay busy.
I have tried by calling a second process from the function, just to make a process_wait_event_until ( etimer expired..) but when the second process is waiting, the program returns to the first process, where the function is running, so it doesnt works too.

Any idea? Maybe any way to pause the first process from the second process while the process_wait_event is waiting.. and then resume the first process ( if its posible, i dont know..). I have read that the process_wait_event doesnt makes the CPU stay busy so i guess that the packets would be sent while the program is waiting, so i only need a way to pause the first process while the second one is waiting.

If you think that the problem is not the lack of delay between packets, tell me please.

If more information is needed, please just ask for it :)

PD: i am using Contiki-2.7, ATMEGA256RFR2, csma.c and nullrdc.

Hello Guys,
I am trying to connect with rest-server using copper plugin, but it gives error "server" not responding. I am running rest-server within cooja and able to ping it from linux machine but not abel to connect through copper.
I also tried coap-client-server simulation but not able to connect.

Thanks,

A not editable configuration page was present in 1.0 and has been removed in 1.1. It should be reintroduced as currently anybody can access the configuration page and modify the configuration.

Also, a nvm option should be added to select wether the configuration could be modified through the webserver or not.

Dear friends.
iam always struggle with the 6lbr due to getting errors when i typed this command----make all_native.
it's always displayed error i.e "compilation terminated and something else." please slove my issue to know anything on my problem.
Iam appreciate with your help.

thanks.
nagesh.

The neighbour table displayed in the network page of webserver is sometimes garbled. We should add a additional flush buffer action somewhere, either in the loop or before beginning to write the route table

Hi,
Just wanted to let everyone following this project that we now have a mailing list for feature announcements and general discussions on 6LBR dev and usage.

http://lists.cetic.be/cgi-bin/mailman/listinfo/6lbr-dev

Kerry Lynn asked about supporting Slip-Radio on Econotag.

I look forward to getting this working with ingredients I have close at hand: namely the
Raspberry Pi with an Econotag radio.  If you already have this recipe handy
then please point me to it, otherwise I shall gain familiarity by first building
the 6lbr for an Ubuntu system and then move to Raspbian.

Dear developers,
I am very interested in 6lbr, but i don't have the hardware you support. So I made a hardware by myself, using stm32f103ret6 as the main cpu. It has 512K flash and 64K SRAM and I think it is better than MC13224( and MC13224 is hard to buy in China). The ethernet interface I use enc28j60 as you did on Econotag and I have tested it worked. The radio chip I used is at86rf231 and I ported the driver in AVR Raven and it can worked as a leaf node runing coap rest server.
Recently, I have tried to port 6lbr onto my hardware according to the Econotag part in the example but failed. I plug one end of the cable into the RJ45 interface on my hardware, and the other end to my ipv6 router(it runs openwrt) from which my computer can obtain the prefix 2001:1::. But I failed to ping my eth addr or wsn addr. Is there anything wrong with my test method? Do you have some publications besides the website? Or any material that may help me, please send to my email: [email protected]. Thanks very much!! If I succeed I will put my code on github. BTW, I have AVR Raven USB Stick at hand, I usually use it to capture the data with wireshark. Can this help?
Here is my debug output, hope you can find something.

1. I was trying to run 6lbr as rpl root router but it is not able to detect the neighbour nodes when i add some rpl-udp-client and rpl-udp-server in cooja.
2. After running 6lbr as rpl root , now i tried using 6lbr as rpl router , it give following error:-

Dear developers,

1. The 6LBR installed in my Ubuntu 10.04 doesn't auto-generate 6lbr.conf.
2. 6lbr-demo is failed to upload into the Z1 node, with error 'Import Error: No module named serial'. I don't understand why the line 17 in 6lbr/tools/z1/z1-bsl-nopic is appending "/usr/lib/tinyos" in the path? I must install Tiny OS in order to make 6LBR works?
3. Do you have more examples of 6LBR on Linux PC, I need more examples for understanding.

Thank you.

Greetings!

We seem to be having a bit of trouble getting 6lbr up and running on a few Redwire IO's. (i.e. - these: https://redwire.myshopify.com/products/io-embedded-router-contiki-based)

We have followed the directions found here: https://github.com/cetic/6lbr/wiki/Redwire-IO-Configuration

The host OS is Ubuntu 13.04.

Though a bit rocky at first, it appears as though we have managed to successfully build everything.

These are the results of using the loader to upload the "router" image:

So, fantastic, it looks as though everything was flashed. However, now we seem to be stuck.

There is no output on the serial. Should there be? We have assumed 115200 8N1 with no luck. Other configurations also fail to produce output.

Following the connection guide here: https://github.com/cetic/6lbr/wiki/6LBR-Connection
seems to allow us to connect. (eth0 shows connection at least)

eth0 Link encap:Ethernet HWaddr (eth0 MAC)
inet6 addr: bbbb::101/64 Scope:Global
inet6 addr: (eth0 IPv6 address)/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

What should the address of the Redwire IO be? We presumed bbbb::100 but

user@host:~$ ping6 -I eth0 bbbb::100
PING bbbb::100(bbbb::100) from bbbb::101 eth0: 56 data bytes
From bbbb::101 icmp_seq=1 Destination unreachable: Address unreachable
From bbbb::101 icmp_seq=2 Destination unreachable: Address unreachable
From bbbb::101 icmp_seq=3 Destination unreachable: Address unreachable

Alternatively, the broadcast: ping6 -I eth0 ff02::1 produces responses only from eth0's IPv6 address.

Additionally, we cannot reach the webserver http://[bbbb::100]. Should we be able to or does this require further configuration?

Ideally, we would like to be able to set up a transparent link between two Redwire IO's (i.e. - what goes in the IPv6 ethernet interface of one comes out the other and vice versa) but we can't even seem to verify that a device is working at all. How can we tell?

Any information that anyone can provide would be greatly appreciated.

Thank you in advance for your support.

nvm_tool does not handle endianness properly (It assumes little endian) We should replace UIP_HTONx() macros from Contiki to proper call of htonx()

Hi,

Thanks for suggestion but I didn't try the Python2.7 yet. The 6lbr still not works for me.

Everything is configured as default except that

1. /etc/6lbr/6lbr.conf (RAW_ETH=1 and DEV_ETH=eth1)
2. /6lbr/examples/6lbr/package/etc/6lbr/6lbr.conf.example (#DEV_ETH=eth1)
   because my 6LBR is connected to a Eth1 interface.

The Ubuntu client unable to connect to the [bbbb::100]. Can you point out me where I did wrong.. Thank you.

The first packet towards an Ethernet new neighbour (the packet that has triggered a NS/NA handshake) contains RPL Hop-by-Hop extension header. Because of that extension header, the packet is dropped by the host. This explains why sometimes the connexion towards 6LBR seems to hang but is fine when we refresh the page.

When make build-cooja fails as root in one of the COOJA plugin build steps (for reason I have yet to determine), the rest of the build fails, and we never go through the few lines of bash that edit ~/.cooja.user.properties

I was trying to run the 6lbr on the MIPS platform. I am using D-LINK router running openwrt linux. These routers are much cheaper then raspberry pi/beaglebone and come with inbuilt wifi capabilities.

I successfully cross compiled the 6LBR code using the MIPS uClibc and the mips gcc.
I could not get the startup scripts(init.d and /usr/bin/6lbr) running. the openwrt uses the ash shell whose syntax differs significantly from bash. So i just thought i would run the binaries manually to save time and effort
.
Here is how i started the binary
/usr/lib/6lbr/bin/cetic_6lbr_router -c /etc/6lbr/nvm.dat -s /dev/ttyACM0 -t tap0 -R -B 115200 -U /usr/lib/6lbr/6lbr-ifup -D /usr/lib/6lbr/6lbr-ifdown -w /usr/lib/6lbr/www

I have all the necessary dependency installed on openwrt
-brctl
-ip

Hello,

I am trying to simulate 6lbr in cooja following the tutorial you provide. But, when i try to launch 6lbr, i obtain an error which says that SLIP can't connect to localhost.

This is what i obtain when i execute

Hi, guys:
Today I use 6LBR and cc2538 board to do a test, when I use the 6lbr-demo example the board works well. But when I use the ipv6 example(udp-clinet or udp-sever) the node can't get the aaaa:: prefix. On the 6lbr network page the node only appears under the Neighbors title, not appears under the Routes title. Could someone tell me why? And how to solve the problem if use udp-client or udp-server?

Regards,
Hengli

Hi, does the 6lbr examples work on a SMARTrf06 evaluation board with a cc2538 on it?

We are pleased to announce that Version 1.3 of 6LBR is available. This
version is merged against the latest Contiki, it provides CoAP over DTLS
support (Interoperable with native TinyDTLS and Californium), many RPL
stability improvements, better reliability of slip-radio and many others
bugfixes. See the changelog below or the Wiki for more information.

As the RPL modification are not yet merged into Contiki, it is
recommended to build your motes and slip-radio inside 6LBR tree.

Hi, we are using 6LBR 1.0 in BeagleBone Black with our Atmega128-RFA1 based platform (www.batmote.net). The problem occurs when we put two border routers nearby, one in channel 25 and the other in channel 26. It is not automatic, but after some hours, somehow a new DODAG from one of the networks appears in the other one and everything mess up. How is this possible?

Hello Guys ,
I have cloned the latest version 1.3.1 of 6lbr, i am trying to compile /example/6lbr-demo/ for cc2538dk evaluation module ,its compiled perfectly and able to flashed it, Now to connect it from client i need t make er-rest-client natively, but when i m trying to do that by the command "make TARGET=native er-rest-client-example , its not happening.
I have not changed anything into the code i m just compiling the code what has been provided.
Its showing the errors ,
In file included from er-example-client.c:57:0:
../../apps/er-coap-13/er-coap-13-engine.h:89:17: error: too few arguments to function ‘coap_blocking_request’

^
er-example-client.c:142:7: note: in expansion of macro ‘COAP_BLOCKING_REQUEST’

Thanks ,

Hi,
I intend to install 6lbr on my naptop with ubuntu12.04,but I can't make it.
Under the example/6lbr I use the command "make all_native" but finally it print the following error message:

../../platform/native/ctk/ctk-curses.c:34:20: fatal error: curses.h: No such file or directory
compilation terminated.
make[2]: *** [obj_native/ctk-curses.o] Error 1
make[2]: Leaving directory /home/li-ubuntu/Documents/cetic-6lbr-74dac48/examples/6lbr' make[1]: *** [bin/cetic_6lbr_smart_bridge] Error 2 make[1]: Leaving directory/home/li-ubuntu/Documents/cetic-6lbr-74dac48/examples/6lbr'
make: *** [all_native] Error 2

could someone give some help?

I seem to be having a bit of trouble sorting out the NVM settings.

It had been mentioned in Issue #48 that:
"About connecting two IO, it is not possible using RPL enabled builds. What you have to do is either use the NDP-Router mode and the two IO will act as vanilla IPv6 routers. Another possibility is to use full transparent bridge mode, in that case each IO will forward packet received on one interface to the other and vice-versa. (please note that this mode is untested on IO, although it should work)"

While Redwire IO's fit my specific application, the question/request for documentation is general and could apply to any 6lbr device.

Here is what my nvm.dat file looks like:

Reading nvm file 'nvm.dat'

Any documentation other than that mentioned at: https://github.com/cetic/6lbr/wiki/Nvm-Tool would be useful perhaps? What settings might need to be adjusted to get two devices to connect to each other? Links to external documentation referring to what these settings mean (or should be set to) would also be perfectly acceptable.

Currently one has to recompile 6LBR to change the amount of log produced by 6LBR. For modules under 6lbr/ (at least packet-filter and rap-tap-drv) it should be possible to configure at run time if they should print out logs or not, like what it's done in slip driver.

Also, we should add in 6lbr.conf two new parameter to configure the actual log files (LOG_FILE=..., ERR_FILE=…)

6LBR requires that slip-radio performs a reset at 6LBR startup (in order to start from clean condition). However, on Econotag the function watchdog_reboot() is empty and the slip-radio keeps using the old configuration.

I wrote a small walkthrough for interfacing a 6LBR with a simlulated WSN.
The doc needs a double-check on a clean config to make sure I didn't miss a step.

Hello,

    my scenario is the following:

I have two raspberry pi respectively attacked with a telosB each. I would like to send a raspberry to another COAP a package with a java application made ​​by me.

Example starting the program Test.java 4000 192.168.0.2:5000 a raspberry is listening on port 4000 and sends CoAP packet to the address 192.168.0.2 port 5000.

With a wifi interface everything works perfectly. Now I would like to replace the wifi with two telosB.

In practice I would use the two telosB as communication interface (not using wifi or ethernet). What programs do I need to load on telosB and how should I configure the two raspberry? How do I assign the interface tap0 a certain address (eg 192.168.0.3)?

thanks

Hello Guys,
I am using cc2538dk EM kit for my purpose, i have gone through the whole "Hello 6lbr" thread and able to set-up everything, but when i access the 6lbr-border router web page using "[bbbb::100]" address i am not able to get any entry in the node field, i am attaching the image of that.
One more problem i am having that when i access the module on which 6lbr-demo is been flashed through UART , i am not getting any "Tentative IPv6 address " on screen as it shows on cooja , and i have tried same thing on STM32W platform there i am getting "Tentative IPv6 address". But on cc2538dk i am getting only following
Contiki-6lbr-1.3.1
TI SmartRF06 + cc2538EM
Net: sicslowpan
MAC: CSMA
RDC: nullrdc
Rime configured with address 00:12:4b:00:89:ab:cd:ef

So it should be like that only or it should show IPv6 address too.
Please Help
Thanks

Any way to ease development of an RTLS with 6lbr?

Cooja plugin serial2pty is broken on MacOS-X, for very strange reason (bug), when a pty is created, everything that is written on the master pty is read back on the master. One have to connect a slave pty to end this erroneous behaviour.
Because of that bug, mote's serial output is directly fed into their input and after a few seconds the whole simulation collapse due to this infinite loop.

It seems that the default value of LIB_6LBR is wrongly inferred when not specified in 6lbr.conf

6lbr-functions line 75 :

LIB_6LBR=`dirname $0`/../lib/6lbr

should be replaced by :

LIB_6LBR=`dirname $BASH_SOURCE`

Otherwise LIB_6LBR depends on the calling script location

Or one could set up LIB_6LBR explicitly in 6lbr.conf

LIB_6LBR=/usr/lib/6lbr

Dear developers.

I sat up an SLIP-radio with stm32W108cB controller with my custom board. But I read this between the debug log file:
2013-10-12 19:29:25.460826: ERROR: PF: No input function set
I downloaded the precompiled 6lbr and installed to Rpi with Raspbian. RADVD running and configures the bridge and the IP addresses.You can find the attached files at:
https://drive.google.com/folderview?id=0B0T6b2efIoQ5NkdqSV9lclpIMU0&usp=sharing

I need to make a border router using the wifi (I have a usb dongle) and let me know if you can use the examples that we are here on github. How do I set 6lbr on wlan0?

When using an Econotag based slip-radio, packet fragmentation is not working. Only the first fragment is sent, all the others are dropped.

Multi-BR support option in webserver is not working : in update_config() the code handling the option is missing.

Workaround : use nvm_tool with -smart-multi-br option

Hello Guys,
Using following command i run the daemon
devesh@devesh-Inspiron-5420:~/6lbr/examples/6lbr$ sudo /etc/init.d/6lbr start
Following error has been throwing

• Starting 6LoWPAN Border Router 6lbr
  /usr/lib/6lbr/6lbr_run.sh: 13: /usr/lib/6lbr/6lbr_run.sh: /usr/lib/6lbr/bin: Permission denied

Thanks

Currently the Makefile targets (launch-6lbr-router-1-cooja) which allow to launch COOJA automatically and connect a 6LBR to it does not use to auto-start mode of the UDP clients. It would be good for a newcomer to not have to deal with starting udp clients manually, so he can visualize the DODAG as soon as the webserver is UP.

The targets need a bit of refactoring to allow with or without auto-start.

Hello Guys,
In the rest coap-client the ip address of server is hard-coded, but in real deployment how we'll come to know the ip address of coap-server dynamically. Which API of 6lbr will able to get it.
Thanks.

Hi All,

I have few basic questions regarding 6LBR,

1, what is the purpose of TAP interface in 6LBR, why it's needed to bridge the TAP interface with Ethernet ?
2. The 6LBR is hardcoded with BBBB::100 to access the webserver, but, when I run "ifconfig -a", I cant see on which interface that addressed is set.

Thanks for your englightenment.

Sundi

Hi,

I am attempting to use 6lbr for my dissertation project but cannot seem to get it to work.

I have installed it on the Raspberry Pi and 6lbr starts okay in the terminal windows. However, when I try to 'make' the hello-world example I get errors saying that curses.h and term.h cannot be found in "../../platform/native/ctk/ctk-curses.c". I am sure there is something I am doing wrong and was wondering if anyone could point me in the right direction. I am using a Raspberry Pi with the Nooliberry add-on

Thanks,
Ben

Hello Guys,
I am trying to compile rest-server-example for my platform which having cc2530dk core, so its giving following error,

CC ../../apps/rest-coap/coap-

../../apps/rest-coap/coap-common.c:69: syntax error: token -> 'uint16_t' ; column 10

../../apps/rest-coap/coap-common.c:90: error 20: Undefined identifier 'i'
make: *** [obj_cc2530dk/coap-common.rel] Error 1

So why these errors are coming and what changes i need to do to get rid of them.

Thanks

Currently we can only set the 802.15.4 channel and not the PAN-ID which is hardcoded inside the slip-radio. Also, it is not possible right now to retrieve the actual configuration of the slip-radio and its MAC layer, one has to look inside 6LBR logs.

We should add a command to set the pan-id and also to retrieve the slip-radio configuration. Note that these command will break the compatibility with Contiki slip radio. If we can not push our modification into Contiki either we develop two slip-radio interfacing code or we require now that only 6LBR slip-radio can be used.

Sometimes S11xx tests are failing because of interferences between the background pings and the test ping. When commenting out the background ping process the tests are successful.

Webserver commands, like log, restart, halt, rpl-gr, .. should be accepted with or without the query mark : ?

Some browser automatically adds it, others adds it only if there are actual parameters to be transmitted.

Currently it's difficult to see when there's an error in the test framework due to COOJA not starting (which can fail for a number of reasons).

signal this in the top-level trace, and cat the last few lines of the COOJA.log

Hello!

I am sorry to bother, but I am interested to get access to the other sensors of a Sky mote (e.g. GPIO, battery, power) in a manner similar with collect-view or sky-shell (the lightest way possible, no java application, no web-server). I am wondering if you can point me to a documentation showing how I can access remotely a Sky mote running 6lbr stack.

Any other idea will be highly appreciated.

Thank you in advance for your time!

Dear developers,

I'm planning to integrate the current 6LBR with non-ip devices using rime communication.
I want all all rime-based node associate them selves with current border-router, the web-server on border router should then able to display those non-IP devices (rime devices).

Any clues on how to start modification of current 6LBR code to enable the above communication

Regards
Sundi

When many packets that requires fragmentation are forwarded by 6LBR towards WSN, the fragmentation system fails and only the first fragment of every packet is sent until the traffic slows down.

Hello Guys ,
I am trying to run er-rest examples , i m trying to get the response payload of helloworld resource at the client side but i am not able to get the payload.
