at86rf233 in Raspberry Pi 3

at86rf233 in Raspberry Pi 3

[Tao Liu]

Dear list,

I am trying make at86rf233 radio from openlabs work with Raspberry Pi
3. I followed the guide here:
https://github.com/RIOT-OS/RIOT/wiki/How-to-install-6LoWPAN-Linux-Kernel-on-Raspberry-Pi,
but it seems do not work well in Raspberry Pi 3.

So far I can
- see "at86rf230 spi0.0: Detected at86rf233 chip version 1" in dmesg
- use iwpan command to list wpan0 interface and set pan_id/short_addr/etc.
- create 6LoWPAN interface
(http://wpan.cakelab.org/#_setup_a_6lowpan_test_network)

But I cannot ping other Raspberry using wpan-ping tool, and pinging
through 6LoWPAN interface also failed. Can anyone give me some
pointers about how to setup at86rf233 for Raspberry Pi 3?

Thanks in advance,
Tao

Hi Tao,

the RIOT-OS Wiki-Guide is rather outdated on this, please have look at [1] - this approach works for me and I heard from other, successfully using that one too.

Best,
  Sebastian

In my experience the most challenging part of this is getting the right
upstream RPI3 kernel things with and the right linux-bluetooth-next stuff.

On RPI2, everything is upstream, so the bt-next tree just works. That might
not be the case for RPI3... and I'd probably stick to 32-bit kernels/systems
for now, since I still see lots of 64-bit fixes going upstream.

I have two RPI2 unit working fine, but I traded my RPI3 for an RPI2, because
the serial console UART on the RPI3 is wonky. I believe that this is now fixed.

Hi Sebastian,

Thanks for the pointers. I followed the link [1] in your email, but
the at86rf233 does not show in the dmesg, and "iwpan list" command
outputs "nl802154 not found."

In the old (outdated) guide [2], I need to patch the device tree. Do I
need to do the same with the new guide?

Re: at86rf233 in Raspberry Pi 3

Hi Tao,

you don't have to patch the device directly, I use DT overlays. The important steps (different from [2]) in my guide [1] are:

- use latest Raspbian image from [3], see also [4]
- deploy a custom Linux-Kernel using Raspi sources [5], see also [6]
- enable the transceiver using device tree overlays, see [7]

For details and trouble shooting, carefully read my guide top to bottom. 

If the at86rf233 doesn't show up, you likely missed to enable the overlay in '/boot/config.txt'. But for RPi3 you also have to build a custom Linux Kernel, because the default Raspbian-Kernel v4.4 has some issues - the device is visible but is not working correctly.

Anyway, I will have to setup some RPi3 for a project in the next days - I'll let you know if there is any trouble (and how to solve it).

Best,
  Sebastian

Re: at86rf233 in Raspberry Pi 3

[Tao Liu]

Hi Sebastian,

I am able to ping my node now -- thanks a lot for your help!

It turns out I didn't enable the transceiver in /boot/config.txt. I
jumped directly to building the new kernel, and skipped the part 3 of
your guide.

Thanks again for providing the wonderful guide!

Best,
Tao

[Fwd: Re: at86rf233 in Raspberry Pi 3]

[Jan Newmarch]

Hi

I'm still struggling to get two RPi 2 B's to ping each other
with at86rf233 devices. I can see the devices. They can ping themselves
but they can't ping each other. According to wireshark and dmesg, lots
of malformed packets.

Details:

dmesg shows no errors

Wireshark shows errors on this second RPi [image removed for mailing
list]

On the first Rpi, wireshark shows NOTHING. On the other hand, dmesg on
the first RPi shows

ifconfig on the first RPi now shows bytes received on wpan0 but not
making it up to lowpan0 
I guess those are the dmesg errors

Wireshark on the first RPi shows failure [image removed for mailing

The routing table on the first RPi looks ok

The second RPi routing table looks okay too.

I have seen comments about setting the SPI rate. The default rate is
3000000. I'ev used it in all the above. 
Resetting it to 1000000 didn't make any difference, nor did 100000, by
dtoverlay=at86rf233,speed=100000
in /boot/config.txt

As you can see, I've tried a lot of things. What do I do now?

Regards

Jan

Re: at86rf233 in Raspberry Pi 3

[smlng]

Hey Jan,

the v4.4 Linux-Kernel of latest Raspbian is not working with the OpenLabs transceiver. You have to build a custom Kernel, e.g. v4.7 or v4.8 as described in [1]. That should do the trick.

Best,
 Sebastian
