Notes #

Pairing #

Factory reset the light bulb (video). After resetting the bulb will automatically connect.

While pairing, keep the bulb close to the CC2531 USB sniffer.

What works is to use (very) short “on’s” and a little bit longer “off’s”. Start with bulb on, then off, and then 6 “on’s”, where you kill the light as soon as the bulb shows signs of turning on.
