Dear RIOTers, How do I use the csma_sender module? I have a radio (kw41z) which only supports basic CCA before TX, but no auto retry or CSMA behaviour. I've seen the csma_sender module in the code repo and the docs, but it is unclear how to enable it for my radio. Currently if the channel is busy, the behaviour of gnrc together with this radio driver seem to be ignore the failure and drop the packet, instead of retrying a few times, like the hardware CSMA radios do. Do I need to integrate csma_sender with the send function in the radio driver or is it just a configuration change to use it between the gnrc link layer and netdev?
Best regards, Joakim Nohlgård
