Hi Felipe,

All the messages to the firmware seem ok. If connection would succeed I
normally see a LINK event followed by SET_SSID event. In your log I only
see the SET_SSID event with failed status, hence the connect is
unsuccessful. Do you have any control over the AP? Could you try without
WPA security to quickly confirm connection works? May help in root
causing the issue.

Arend
