I think that return code is a bogus caused by the driver debug code, 
because when I remove all the debug I see a different behaviour, i.e., 
after brief associating with the AP, I see 3 driver messages;

wlcore: Beacon loss detected. roles:0xff

and then receive from wpa_supplicant;

wlan0: CTRL-EVENT-DISCONNECTED bssid=88:43:e1:57:79:c0 reason=4 
locally_generated=1
wlan0: WPA: 4-Way Handshake failed - pre-shared key may be incorrect
wlan0: CTRL-EVENT-SSID-TEMP-DISABLED id=0 ssid="A. Guidance" 
auth_failures=1 duration=10

and I've not make any mistake on the pre-shared key.

Also I've used this AP for tests of different wireless adapters with 
success. Inclusive have use it with the same hardware platform and same 
kernel and sysapps (ifconfig, iw, wpa_supplicant, etc...) and a TP-Link 
TL-WN722N Wi-Fi adapter (ath9k_htc driver) and had no problems in 
associating that adapter.

Can my problems be related with an inadequate NVS file? I've generated 
it with the calibrate tool from ti-utils and the INI file TQS_D_1.7.ini 
with the command "calibrator plt calibrate". Is this the correct INI for 
my module (Jorjin's WG7350 - wl1273 based)?

Any ideas also why I can not get a complete APs list with the command 
"iw wlan0 scan"? No one as seen this behaviour before?
