Betaflight: Just a question that I can't seem to find an answer for...

[DubLD]

Can someone please tell me what Dshot Burst does in the cli commands?

[jflyper]

It turns on burst mode dshot.

Difference between regular dshot and burst mode dshot is that former use one dma stream/channel per motor (equals timer channel) while later use one dma stream/channel per timer (all motors = channels connected to a particular timer). Burst mode MAY provide better dma stream/channel resource utilization, slightly less inter-motor skew and slightly more bus bandwidth usage (atm).

Note that not all targets benefit from the burst mode.

Baseline is to leave it alone.

With the average person likely be able to feel / notice the difference?

You will immediately notice if a target does not support either mode and switched to the un-supported mode; motors will not spin 🤣

Otherwise, you will never notice the difference 😉
