hi I too face similar issue. Coudn't connect with my wifi
In the UART log I see
SM = 0 Sub = 0;
SM = 2 Sub = 0; It is stuck at the State Machine 2 I guess SM =3 is where it is connecting to WI-FI which is not happening right now.
I ve tried using 2 android phone
Samsung galaxy s3 and One plus 3T. Ideally it should be independent of type of mobile phones, meaning we wont able to buy a specific phone just to connect to wifi using this module.
