Hi Janna,

welcome to RIOT! Short answer: Yes and no, but we could need more people
working on it :-). Maybe the authors can share further insights. Please
have a look at the following efforts:

https://github.com/RIOT-OS/RIOT/tree/master/examples/gnrc_networking_mac
https://github.com/RIOT-OS/RIOT/pull/6554

https://github.com/RIOT-OS/RIOT/pull/8332

https://github.com/RIOT-OS/RIOT/pull/8570

Best
Peter

[riot-devel] networking

[Janna Om]

Hello,
i am new in RIOT OS.
I want to write an application that uses different mac protocols.
I would like to know if there already exist CSMA, TDMA and XMAC implementations 
in RIOT.
Are there any tutorials or examples available about network configurations and 
communication settings?
Thank You in advance!

Hello Bernhard,

AFAIK autoinit module is enabled by default, just check if you have defined
-DMODULE_AT86RF2XX, -DMODULE_AUTO_INIT_GNRC_NETIF and
-DMODULE_AUTO_INIT_GNRC_NETIF while compiling.

Im not using default toolchain based on Makefiles so Im not that familiar
with it...

Hello malo,
the output of ps show at me the same as you have posted it here with the
exception that there is no at86rfxx. The at86rf2xx driver is compiled - 
I see it there.
And I have no hint - no error message or something like that why it 
isn't loaded.
It seem for me, that at86rf2xx_init is not executed - that 
auto_init_at86rf2xx was
not inivolved in the init-phase. I will check this tomorrow with the 
emulator...
If so - which action/module invokes the execution of 
auto_init_at86rf2xx?  As far

I have seen this are gnrc-netif modules?
Thanks a lot,
Bernhard

Hello Bernhard,

if you are using rf233 the name of the thread is at86rfxx - check with ps
output. you should get something like
> ps
pid |name | stateQ | pri | stack ( used) | location
  1 |idle |  pending Q |  15 |   128 (   96) | 267a
  2 |main |  running Q |   7 |   640 (  440) | 1880
  3 | 6lo |bl rx _ |   3 |   512 (  460) | 1d00
  4 |ipv6 |bl rx _ |   4 |   640 (  484) | 1380
  5 | udp |bl rx _ |   5 |   512 (  208) | 1f00
  6 |at86rfxx |bl rx _ |   3 |   640 (  312) | 1100
  7 |   blink | sleeping _ |   7 |   640 (  180) | 1600

in the function auto_init_at86rf2xx the thread is created only if the radio
was successfully initialized.
do you have no error return from the at86rf2xx_init?

note that im newbie as well:)

Re: [riot-devel] Networking Module does not appear in process list

Hello Peter,
thank you.
Just for your understanding - I just tried to make everything exactly as 
shown in the Iotlab-M3 board but I get not the result which is listed in 
the readme files or the other documentation.
One remark - I think most new RIOT users would resolve their problems by 
themself if they have some documentation about the relationship between 
the modules. It would be also nice to now where it is the right place 
for adding a module (makefile in the board directory / makefile in the 
project directory / makefile in the top directory e.g.).
Where is the correct place to invoke auto_init (I guess the Makefile in 
the project directory)? Is it necessary to load the radio module driver 
manually or will it be loaded automatic (by the make utility)?
You see - a newbie has totally different questions than an implementer 
who works with RIOT since for a long time.

Hi Bernhard,

without looking into details of your problem, just a quick hint from my 
side: The mac layer (nomac) and the device driver are running in the 
same thread which should be automatically initialized in our networking 
examples. I don't remember the name of the thread out of my head...


Did that already help a bit?

Hello everybody,
today I tried to get the at86rf2xx working with my board. I have the
following statement in the board's Makefile:

ifneq (,$(filter gnrc_netif_default,$(USEMODULE)))
 USEMODULE += at86rf233
 USEMODULE += gnrc_nomac
endif

I tried all the networking examples but no example shows the at86rf2xx
networking module when I list the threads.
I see all networking threads but not the driver.

I tried to include (USEMODULE) the Module  in the project makefile and
then i tried to invoke the auto_init mechanism on serveral places -> no
success.

Can you please tell me what I have to do to load the radio module
driver? I think it would be a good idea to write down how it should go
in a tutorial. It's not very nice for newbies to grep through the source
code to find out how it should work and what might go wrong (it a little
bit like beeing Sherlock Holmes but without having fun).

Question 2 - ifconfig:
ifconfig help
usage: ifconfig []

 From where do I get the if_id ?
I think you will get it if you invoke ifconfig without parameters (when
you have a network module thread running). Is this true?

Thanks a lot!
Regards,
Bernhard
