Other Parts Discussed in Thread: MIO

Hi, I have implemented in my work code data to read on the CoAP and so far everything works. Now I would like to save this data on a cloud that works with CoAP. Can I do this with the cc26xx-web-demo? I have the url of the cloud, how can I implement it in the code?

I just download tinydtls-0.8.2 and build it again on my InstantContiki. It can be configured and built without problem.

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

Why to me not function? What is the step that you following?

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

1. Use firefox accessing to sourceforge.net/.../ and download tinydtls-0.8.2.tar.gz
2. Untar it to home folder and cd to tinydtls-0.8.2
3. run "./configure

When I digit make, I have this error.

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

Do you run “./configure” before make?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

I resolve my error

I arrive at this point: route -A inet6 add aaaa::/64 gw bbbb::100 and I see SIOCADDRT: No route to host

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

Try to use fe80 instead of aaaa. By the way, how do you solve the issue? Forget do “./configure”?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

I solved the problem by downloading the file again and following the steps described on the site. I changed from aaaa :: / 64 to fe80: / 64 but it always says SIOCADDRT: No route to host

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

Do you run the following two commands before you run “route -A inet6 add fe80::/64 gw bbbb::100”?

sysctl -w net.ipv6.conf.eth0.accept_ra=1
sysctl -w net.ipv6.conf.eth0.accept_ra_rt_info_max_plen=6

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

Yes, now I see no such device

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

What do you mean no such device?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

When I digit "route -A inet6 add fe80::/64 bbbb::100, I see: SIOGIFINDEX: No such device

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

I see the same problem on my current InstantContiki.

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

Then?

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

Then what? Am I supposed to be the one to fix this issue?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

No, I not tell this. The problem Can it the version of Contiki 3?

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

I remember there is only one version of InstantContiki 3.0.

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

I think you have to run 6lbr on a Raspberry Pi to have bbbb::100 to solve "SIOCADDRT: No route to host" issue.

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

Does it work with a previous version of Instant Contiki, such as InstantContiki 2.7?

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

Try to run 6lbr on Raspberry Pi before you run “route -A inet6 add fe80::/64 gw bbbb::100”.

Hi Yikai, I try to generate the my example with tinydtls. I add the APPS += tinydtls in the Makefile, but when I compile the code I see "fatal error: sys/socket.h no such file or directory. Have I wrong something?

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

I don’t know what’s your problem according to your descriptions

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

I'm creating an example with tinydtls. I added within the Makefile APPS + = tinydtls, and when I go to do sudo make clean and sudo make TARGET ..... I see this error. Depends on what?

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

If you follow step 1 to 9 On SmartRF06EB+CC2650EM side: of sunmaysky.blogspot.tw/.../how-to-build-dtls-example-for.html to build 6lbr-demo.bin, does it build successfully? By the way, have you solved "SIOGIFINDEX: No such device" issue?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

Yes the 6lbr-demo works correctly, but I would like to create an example with the tinydtls library but I see that error in the attached photo. I have not yet solved that problem of SIOGIFIDEX

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

Try to clone a 6lbr-demo example to revise on it. Do you try to start 6lbr on Raspberry Pi to solve SIOGIFINDEX issue.

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

I tried to test it with the raspberry. But when I go to type:

- route -A inet6 add fe80 :: / 64 gw bbbb :: 100

I read, SIOCADDRT: No route to host

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

Can you access to bbbb::100 of Raspberry Pi running 6lbr from InstantContiki?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

How?

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

Use Firefox browser in InstantContiki.

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

No, I not access to 6lbr of Raspberry on InstantContiki

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

Does your InstantContiki and 6lbr Raspberry Pi connecting to the same internet router?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

Yes

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

Are you sure your 6lbr run correctly?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

Yes sure

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

If you are sure about this, how do you access to bbbb::100?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

I access to bbbb::100 on my browser Mozilla Firefox of Windows, but I not access on Mozilla of InstantContiki

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

Can the firefox browser in your Instant Contiki access to any web site? After I start 6lbr on my Raspberry Pi, I am sure it fixes the issue.

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

I testing the tinydtls on Contiki/apps. I following this step:

1) copy tinydtls in contiki/apps

2) cd tinydtls

3) sudo autoreconf

4) sudo ./configure --with-contiki

5)sudo make and I see this error

Where are those steps from?

Scusa il mio errore, mi risolvo. Ora costruisco l'esempio del coap con tinydtls ma quando compilo il file lo vedo:

Guru 735595 points

I don't know what you are typing.

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

I solved the previous error. Now, I'm building the 6lbr-demo with the coap functionality. In the makefile I have enabled TINYDTLS, COAPSERVER and DTLS_COAP. When I go to fill out I get the error that I showed you. What can it be?

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

Why don’t you make a Copy folder "6lbr-demo" under "\6lbr\examples\" to "\contiki\examples" and clone it for your application?

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

I did it. Now I do not want to create dtls-echo but dtls-coap. I have enabled the apps feature in the Makefile. But I have problems with compiling

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

If you do it in different folder level, you have to revise Makefile to include correct source path by yourself.

0 Mark Felberg over 7 years ago in reply to YiKai Chen

Guru 19990 points

I modify the Makefile for Coap, but now I see this error

0 YiKai Chen over 7 years ago in reply to Mark Felberg

Guru 735595 points

It means you still miss some source path.
