Hi. Yes, I still use the set-up. My OpenWRT is currently on 21.02.1, my U6-Lite is on 5.60.1 and UAP-AC-Lite are on 5.43.49. I tried to move to places where signal would force the phone to switch and I watched the transitions using WiFiMan. I started on OpenWRT, roamed to UAP-AC-Lite, roamed to U6-Lite, roamed back to the initial OpenWRT. It was successful, all transitions were done using roaming. I haven't tried using more OpenWRTs, but it should not be a problem if wifi configuration among them is identical.

Can you show me your configs ?I have tried many different configurations but it doesn't work. Thanks.
This is my config:
unifi

Code:

interface=ath5
ctrl_interface=/var/run/hostapd
vlan_naming=1
bridge=br0
driver=atheros
nas_identifier=$bssid
mobility_domain=XXXX
rkh_pos_timeout=10000
reassociation_deadline=3000
pmk_r1_push=1
ft_over_ds=0
r0kh=ff:ff:ff:ff:ff:ff * KEY
r1kh=00:00:00:00:00:00 00:00:00:00:00:00 KEY
ssid=SSID
wpa_group_rekey=3600
wpa_group_update_count=4
wpa_gmk_rekey=86400
wpa_passphrase=PASSWORD
wpa=2
eapol_version=2
wpa_pairwise=CCMP
wpa_key_mgmt=WPA-PSK FT-PSK
logger_syslog=-1
logger_syslog_level=2
wlan_id=XXXX
iapp_key=KEY
own_ip_addr=ip

Openwrt:

Code:

config wifi-iface 'wifinet3'
    option device 'radio1'
    option mode 'ap'
    option ssid 'SSID'
    option key 'PASSWORD'
    option encryption 'psk2+ccmp'
    option network 'lan'
    option ieee80211r '1'
    option ft_over_ds '0'
    option mobility_domain 'XXXX'
    option nasid 'MAC openwrt'
    option reassociation_deadline '20000'
    list r1kh '00:00:00:00:00:00,00:00:00:00:00:00,KEY'
    list r0kh 'ff:ff:ff:ff:ff:ff,*,KEY'
    option ft_psk_generate_local '1'
    option pmk_r1_push '1'

I tried changing r0kh and r1kh but it still doesn't work. With ft_psk_generate_local '1' and same mobility_domain roaming works great between 2 openwrt devices and roaming only works when i move from unifi to openwrt.
