Contiki with MQTT

You can refer to processors.wiki.ti.com/.../Cc26xx_contiki_sw_apps .

I trying but nothing. I see this error:

Can you help me?

I don't see how those errors are related to MQTT.

You see the error !

Can you elaborate what example you build and test?

Look at the error messages. It clearly says, that it cannot find a number of ti_lib things. `ld` is the linker. And, searching for any of those reveals that they are part of the CPU files and driverlib. I would guess that you either have not fully checked out the correct driverlibs (available as git submodules), or are using the incorrect version of those since there was recently a change to the GPIO module in it.

You can see it basically something like this: the compiler takes your source files (.c etc) and creates a bunch of puzzle pieces of compiled object code (.o files), then, it's the job of the linker (the `ld` utility) to connect this together into a binary. What happens is that some puzzle piece uses `ti_lib_thisandthat()` but when the linker looks at them all, it can't find it so it fails with an error. This means that there is a puzzle piece missing, which in turn means that something is amiss in the compiler stage (it could also be that you are not instructing the linker correctly on eg where to find them, but since you are using Contiki this is already taken care of). I'd place my bets on the driverlibs being incorrect in your local copy.

Try to git latest CC26xxware frin github.com/.../cc26xxware

You can use the following commands to do it:

git submodule sync
git submodule update --init

Try to remove everything and git a new Contiki source to build again.

What do you mean nothing?

I just test it and I see no problem. What is your build command?

cd contiki/examples/cc26xx/cc26xxwebdemo/ sudo make clean 

sudo make TARGET=srf06-cc26xx BOARD=srf06/cc13xx mqtt-client.bin

You cannot build MQTT-client.bin under cc26xx-web-demo folder like this.

How?

You should use "sudo make TARGET=srf06-cc26xx BOARD=srf06/cc13xx cc26xx-web-demo.bin" to build cc26xx-web-demo example and there is MQTT client in CC26xx-web-demo.

How do I use MQTT-client? How do you build it?

As I replied in previous post, MQTT client will be included in cc26xx-web-demo.

Try to refer to processors.wiki.ti.com/.../Cc26xx_contiki_sw_apps

So how do I code the device to enter the broker IPv6 address?

I suppose you can input broker IP and port in MQTT setting page.

processors.wiki.ti.com/.../File:Contiki_webserver_config.PNG

Where can I see the address?

I couldn't understand your question. Can you elaborate?

The address of the device to be placed on the broker, where can I see it?

The broker IP is the IP address of MQTT broker not device.

Ok, I found it in mqtt-client.c. But he does not get me into the broker

What do you mean "he does not get me into the broker?"

I can not access IBM

What is your border router?

I use a cc26xx-web-demo.bin and cetic-6lbr router

Try to run tcpdump on linux console of your cetic-6lbr router to see if anything is sent out on port 1883

tcpdump –X –v –i eth0 port 1883

Do I have to write this on the terminal?

This command is used for checking if there is MQTT traffic go through port 1883.

I'm not leaving anything

I couldn't understand.

Use "sudo tcpdump..." to run again.

What should it look like?

It should look like i.stack.imgur.com/bT5xU.png

It does not come out to me, it does not seem to me

That means there's no MQTT traffic so I suggest you to use sensniff to check if your cc26xx-web-demo sends MQTT message over the air to your 6lbr GW first.

Ok, I use the cc26xx-web-demo with the cc13xx and the 6lbr device with the gateway ENC28J60 Or the slip-radio

I couldn't understand your descriptions. Can you elaborate?

I use cc13xx (cc26xx-web-demo.bin) and the gateway. But I can also use the slip-radio with Raspberry

So, what's your point?
