Post Body

I read an older article that talks about reducing power consumption on an ESP8266. As a part of his experiments, the total time to establish the connection is shown in his graph.

I'm developing an application that is composed of:

A unit that is mains-powered and is always on

and

Two units that stay asleep and wake with a pin interrupt.

My application is rather time-sensitive, so I'm curious: Between BLE and ESP-Now, does anyone have information on how long it takes to establish those connections?

Any idea where I might find the info? I've scoured the interwebz to no avail...
