Hey folks!

Relatively new to the ESP8266, using the nodeMCU as a streaming wireless ws2812b pixel controller, and I’ve been running into a couple walls.

  1. Is it feasible to communicate with 10+ 30+? 100+? nodeMCU’s streaming relatively large amounts of pixel data (1536 bytes at 30 or 60 fps)?

I’ve already had some successful tests with a few nodeMCU’s:

Basically curious how well this can scale with a powerful router, and what sort of problems / limitations one might run into.

  1. On the subject of routers, do the ones that use MIMO technology work fine with esp82266’s?
    https://en.wikipedia.org/wiki/MIMO

My understanding is that MIMO is kind of like parallel streams of data from multiple antennas going to various devices at the same time, kind of like multi threading.

My assumption is that this is fine, but any other thoughts on this?

  1. Lastly, Unicast vs Broadcast - which is more efficient with large numbers of esp’s receiving constant streams of data?

I would assume Unicast is better since it limits the load being put on each nodeMCU by not blasting it with all of the data leaving the router entirely…
but is that line of thinking true?
