Still the same with wifi_station_set_reconnect_policy(0):

Could you test with this libnet80211.a?

libnet80211.a.zip

And provide the entire logs for debugging?

Same result, but no debugging message besides "switch to channel 2" after calling wifi_station_scan(). Should I try to change wifi_station_set_reconnect_policy(1) to wifi_station_set_reconnect_policy(0) as well?

Hi st0ff3r,

Could you have a try with the new test lib?

libnet80211-test2.a.zip

(113.11 KiB) Downloaded 27 times

If possible, could you provide captured Wi-Fi packets for analyzing?

Thanks.

[st0ff3r]

Sure, I'll do that

Hereby attached tcpdump wifi capture file and serial debugging output of the following scenario:
1. esp 8266 connected to ssid "Loppen Public" on channel 1
2. "beacon_spammer" sending out CSA's on channel 2
3. tcpdump running on same host as "beacon_spammer" on channel 2

Thanx a lot for your help to debug
