Still struggling with this

May 15 22:23:46 pi-loft homebridge[25435]: [2018-5-15 22:23:46] [Broadlink RM] Scan RF (scanning) May 15 22:23:46 pi-loft homebridge[25435]: [2018-5-15 22:23:46] [Broadlink RM] [Hold down the button that sends the RF frequency] May 15 22:23:54 pi-loft homebridge[25435]: [2018-5-15 22:23:54] [Broadlink RM] Scan RF (found frequency - 1 of 2) May 15 22:23:54 pi-loft homebridge[25435]: [2018-5-15 22:23:54] [Broadlink RM] [Keep holding that button!] May 15 22:24:07 pi-loft homebridge[25435]: [2018-5-15 22:24:07] [Broadlink RM] Scan RF (stopped - 20s timeout) May 15 22:24:07 pi-loft homebridge[25435]: [2018-5-15 22:24:07] [Broadlink RM] Scan RF (stopped) May 15 22:24:10 pi-loft homebridge[25435]: [2018-5-15 22:24:10] [Broadlink RM] Learn Code (ready) May 15 22:24:20 pi-loft homebridge[25435]: [2018-5-15 22:24:20] [Broadlink RM] Learn Code (stopped - 10s timeout) May 15 22:24:20 pi-loft homebridge[25435]: [2018-5-15 22:24:20] [Broadlink RM] Learn Code (stopped)

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.

Research direction
The issue describes a user struggling with RF learning on Broadlink RM Pro where the scan/learn sequence times out most of the time. The problem might be related to timing or RF frequency detection logic. Investigate the learnRF function in the homebridge broadlink rm plugin, specifically the scanning and learning steps. Check for any known issues with firmware version 3.55 or hardware variant RM33220. Review any related PRs or comments in the issue #375 for additional context.
