<p>By the way there's a bug in the <a class="issue-link js-issue-link" data-error-text="Failed to load issue title" data-id="232162594" data-permission-text="Issue title is private" data-url="https://github.com/RIOT-OS/RIOT/issues/7107" data-hovercard-type="pull_request" data-hovercard-url="/RIOT-OS/RIOT/pull/7107/hovercard" href="https://github.com/RIOT-OS/RIOT/pull/7107">#7107</a> CSMA implementation that prevents any retransmissions from actually happening if the initial CCA fails.</p>
<p>After <code>_isr_event_seq_t_ccairq()</code> calls <code>kw41zrf_tx_exec()</code> to retransmit the last frame, <code>_isr_event_seq_tr()</code> aborts the sequencer prematurely by calling <code>kw41zrf_set_sequence(dev, dev->idle_seq)</code> while handling <code>ZLL_IRQSTS_SEQIRQ_MASK</code>.</p>
<p>But with that fixed I think it works as intended.</p>
