Linux/CC1310: CC1310_PING6 Issue

PRINT6ADDR is an API just dumping the content of address pointer you input as a parameter. I think the problem is that somewhere in the application changes the content of address pointer. I suggest you to check it first.

Dear sir,

If this is the address pointer isuue means every time it should give PRINT6 address issue,but i am able to print the address successfully but sometimes we are getting this issue.

Regards,
Rajesh.M

How do you call PRINT6ADDR in your application?

Dera sir,

This is our Application please check,

This is not example code in Contiki. I have no idea how to check it.

Dear sir,

We are using the Chip set CC1310F128RSMR.we have downloaded the latest 6lbr-1.4.x from the Git. In this we modified the example code
in examples/ipv6/ simple-rpl-udp. In the application we are register the simple-udp connection with call back receiver function.In the receiver call back function we are printing the remote LPR IPV6 Adderess using PRINT6ADDR.if we call this function we are facing this issue.
please reply.

Dear YiKai Chen,

I used broadcast-example.c example from Contiki (Contiki/examples/ipv6/simple-udp-rpl) and run Run "make CC26XX_NVM=ext TARGET=srf06-cc26xx BOARD=launchpad/cc1310 all" for LAUNCHXL-CC1310 

I used two Launchpad CC1310 board, after load broadcast-example.hex to both LaunchPad, and run Tera terminal, It's show only "Sending boardcast". Please show me what happen.

Do you setup 6lbr?

Dear YiKai Chen,

I used Contiki, not using 6lbr.

Do you setup any edge router? If not, two LAUNCHXL-CC1310 cannot communicate to each other.

Dear YiKai Chen,

I only used two LaunchPad, How can I setup an edge router? Please show me the way?

Try to refer to sunmaysky.blogspot.tw/.../spi-connection-between-launchxl.html and sunmaysky.blogspot.tw/.../build-6lbr-for-cc2650dk-or-cc1310dk.html

Dear YiKai Chen,

Thanks for your help, so that, one Launchpad we will using 6lbr and download cetic_6lbr_router.bin and another kit will load broadcast-example?
Thanks,

I think you need to have 3 LAUNCHXL-CC1310, one runs cetic_6lbr_router, and anther two run broadcast-example.

Dear YiKai Chen,

How can I setup chanel in broadcast-example to 25? And I want to ask you why I got 

"INFO: ENC: resetting chip"

You can add "#define RF_CORE_CONF_CHANNEL 25" in project-conf.h of your 6lbr and broadcast-example. As for why you get "INFO: ENC: resetting chip", do you connect ENV28J60 to your LAUNCHXL-CC1310?

Dear YiKai Chen,

For 6lbr, it run in chanel 25 as image, and I use ENC28J60

Can you open web page [bbbb::100] from Firefox?

Dear YiKai Chen,

I used Chrome and still open webpage.

It looks running correctly. What's your issue?

Dear YiKai Chen,

Sometime It's show on terminal  "INFO: ENC: resetting chip"

And I still don't make broadcast-example work in Chanell 25

1. There might be something wrong with latest 6lbr. You can go to /6lbr folder and run "git checkout ff69ae4214407eeec4c71f87589ac4bc7d3a8a49". You will get 6lbr version on 2016 Dec. 22th and you can rebuild 6lbr to test again.
2. I suggest you to setup sniffer to check if message is sent over the air.

@Cuong Do Dinh, I test broadcast-example and I can see it broadcast/receive broadcast message between two LAUNCHXL-CC1310.

Dear YiKai Chen,

Thanks for your help. I will try it. So that we don't need ENC26J80? When we load broadcast example, it's include of mesh function for Launchpad board? Or not?

How can I use Mesh function for LaunchPad board?

Dear YiKai Chen,

It's work well with two board using broadcast-example.c as image file I attached, How we can do setup mesh function for Lauchpad board? How we can use  discovery to join network , accept network,... in Contiki?

Thank so much.

Actually, you need ENC26J80. I just don't do a screen shot of my LAUNCHXL-CC1310 with ENC26J80. Mesh function is native supported when you run Contiki 6LowPAN.

Dear YiKai Chen,

How can I to do to run Contiki 6LowPAN? Is it I must use BB Board or Raspi board for this?

Thank so much for help.

You already run it, don't you? broadcast example is one of Contiki 6LowPAN working examples. I would suggest you to include BBB or Raspberry Pi to do more test with Contiki 6LowPAN.

Dear YiKai Chen,

Thank you very much! I will test with BBB and Raspi board.
Hope you can help.

You can refer to sunmaysky.blogspot.tw/.../setup-6lbr-to-run-6lowpan-with-cc2531.html which shows you how to setup 6lbr on Raspberry Pi or BBB to test Contiki 6LowPAN.

Dear YiKai Chen,

Thanks so much. I will follow you.
