It will work maybe 1 in 30 times... sequences such as:

1. scan on, scan off, learn on ... time out,
2. scan on ... learn on .. timeout...
3. learn only ... timeout
4. scan only .... timeout.

I never see "found frequency 2 of 2" but the learning sometimes works anyway

All will work ocassionally... none more than 1 in 30 times.

Run serial no RM33220xxxxxx version 3.55 of Broadlink, ver 0.4.42 of Homebridge running on a RPi 2 with hardwire connection to wi-fi router that Broadlink is attached to.

All can be captured correctly via official app on the iphone.
