Riot: LWMAC/GOMACH on Openmote-b

It should be possible with minimal effort to get both LWMAC and GoMacH working on any platform that has periph_rtt available. I don't know whether that includes openmote-b.

If you need a port of LWMAC or GoMacH from periph_rtt to xtimer you can try this branch, but I haven't maintained either port since a year ago aside from merge conflicts and I don't know whether they still compile or work.

If you can post what compile errors you're running in to that would help someone guide you to getting it working.

Yes, that is ture! Both GoMacH and LWMAC need RTT module for timing.

Also, make sure that openmote-b supports radio RX-start and TX-END interrupts (at least, GoMacH relies on these hardware functionalities).

Hi @benemorius, @zhuoshuguo and @miri64,

I have just tested the gnrc_lwmac.c file under the tests directory in order to test the MAC layer on openmote-b, and I have changed the BOARD_WHITELIST to openmote-b in the makefile, and everything compiles successfully with this warning (There are unsatisfied feature requirements: periph_rtt EXPECT ERRORS!)
And I was successfully able to send and receive packets between 2 motes (please see the attached picture).
So, my question how it is possible to get rid of this error/warning? and am I able to send and receive in this way with lwmac?

The picture shows 2 messages sent from one mote to the another using the txtsnd, the first one is a unicast and the second is a broadcast.

The Error I am getting.

Thank you,
Nancy

Hi @benemorius, @zhuoshuguo and @miri64,

I would like to update you that I have solved the error/warning related to the both LWMAC and GoMacH by adding the rtt feature in the makefile of the directory that I was testing. and hence the problem was gone.

Thanks,
Nancy
