5 years ago not esp32 specific but the only data ive come across. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5751532/
seems to indicate to me a .650s window with 1.250s interval optimal for power. but who knows.
My requirement is to purely scan for ble devices, advertisements - with no connection whatsoever to any other ble devices. I was wondering if anyone here has an idea as to what the optimal values (setInterval, setWindow) for pure ble scanning would be? Default of 100/99 seems to work but sometimes it does miss some devices that are nearby even though my scantime is 10 seconds and the ble devices advertise every 3-4 seconds.
As we speak I am trying to write a little program that will vary the values for setInterval/setWindow and "keep a count of hits". This way I can narrow down on the values that gives better result. But I thought I'd drop in a question in case someone has some ideas on this? Wonderful library btw, thanks
