usteer is sending beacon requests in a wrong way, that's why it's not working properly for me.
I always receive beacon responds in this format:
hostapd: wlan1: BEACON-RESP-RX xx:xx:xx:xx:xx:xx xx 04 0000000000000000000000008000000000000000000000000000
When sending beacon request manually with mode: 0 ,It's receiving the correct beacon respond :
ubus call hostapd.wlan1 rrm_beacon_req '{"addr":"xx:xx:xx:xx:xx:xx", "op_class":0, "channel":1, "duration":1, "mode":0, "bssid":"xx:xx:xx:xx:xx:xx"}'
DAWN have the option to set beacon mode, usteer does'nt .
it's a pity, I think usteer have very good potential, but this beacon responds makes roaming to not work at all .
