How does rrm work?

Installing and Using OpenWrt Network and Wireless Configuration
38

Thanks, this script is working (modded it to include udp instead of nr). I can see a successful Neighbor Request and Neighbor Response on ath10k-ct-htt, hostapd-2.9 with openssl. The setup includes 2x Archer A7s Dumb APs with a WRT1900ACS router (disabled wireless functionality) – all three have OpenWrt built from the master branch.

Additional roaming settings were: 802.11r with FT-over-the-Air, 802.11v with BSS transition, 802.11k with list populated by your script.

This is my config in /etc/config/wireless:

config wifi-iface 'default_radio0'
	option device 'radio0'
	option network 'lan'
	option mode 'ap'
	option ssid 'OpenWrt'
	option encryption 'psk2+ccmp'
	option key 'XXXXXX'
	option dtim_period '3'
	option ieee80211r '1'
	option ft_psk_generate_local '1'
	option ft_over_ds '0'
	option ieee80211v '1'
	option bss_transition '1'
	option ieee80211k '1'

The following capture shows an exchange between an Archer A7v5 and an iPhone 11 Pro on iOS 13.3.

In the neighbor report I see four APs, (corresponding to 2x N SSIDs and 2x AC SSIDs).

However, I have an issue with your script whenever I reboot the APs. I have to keep restarting them (3x on each AP) to populate:

  1. ubus call hostapd.wlan0 rrm_nr_list
  2. ubus call umdns browse
