Re: Benchmarking latency across common wireless links for microcontrollers
#2We nerd sniped ourselves into testing the latencies of a whole bunch of wireless communication links and protocols for microcontrollers.
We’ll probably do a series of power consumption / range tests later on, let me know if there are any setups in particular that you’d be interested in seeing test cases for.
Raw data, firmware and post processing scripts are here on GitHub:

#3This is one of the most thorough and well laid out analysis of useful hobbyist and low level research options out there. I'll be referencing this for years, thank you very much. Clearly a lot of effort has been put into this.

Once there's decent embedded HaLow options, I would love to see analysis of this level on it.

#6If we had more great reviews like this we'd see hardware improve faster! Thank you! Shine that light!

#7Outstanding blog post. NRF24 had been my fav for a long time, I planned switching to LoRa but I didn't know the latency is that high.

I nearly did, but the write-up was getting pretty long.
I'll try to find something for the planned range/interference tests. Morse Micro is also an Australian company so I'll probably look into their parts first unless there's any recommendation?

#9That is great stuff, many thanks for it. While not in such depth, for a precision timing network covering multiple sensors our analysis also showed that the delays and variation inherent in most higher-level radio protocols are far too high for microsecond-level synchronisation.
For this reason, we use the nRF52 radio peripheral directly (i.e. barebones C) which means we know exactly when the packet was sent and - at the other end - when it was received. Details are in the Production Specification document, which also shows how long it takes for the transmit to spin up (turn on, transmit pre-amble and so on).

#10Something of a tangent but I couldn't find anywhere a way to wirelessly extend usb ports. Allowing you to plug a mouse/keyboard/Yubikey to a computer in another room with minimum latency and without the need of any software or particular drivers.
If one wanted to do something like that one would probably start by reading that article I guess.
Thanks for this very thorough work.
