Hi,

 

As above I have a wifi connection that frequently drops out. Typically with the following, but instantly reconnects:

CFG80211-ERROR) wl_is_linkdown : Link down Reason : WLC_E_LINK
link down if wlan0 may call cfg80211_disconnected. event : 16, reason=1 from 18:83:bf:cb:66:21
CFG80211-ERROR) wl_is_linkdown : Link down Reason : WLC_E_LINK
CFG80211-ERROR) wl_notify_scan_status : scan is not ready
CFG80211-ERROR) wl_cfg80211_connect : Connecting with18:83:bf:cb:66:21 channel (6) ssid "BTHubIsABoxOfJunk", len (17)

 

wl_bss_connect_done succeeded with 18:83:bf:cb:66:21
wl_bss_connect_done succeeded with 18:83:bf:cb:66:21

 

Power saving is off. Once connected via wpa_supplicant etc, what keeps/monitors the connection state between the AP and my board? Is something exchanged on a frequent basis between the warp7/imx7 and AP? Or once connected does the connection wait forever silent for an AP disconnect like TCP or visa-versa?

 

Thanks,

Ed.
