Mustafa Kamoona / Mbed 2 deprecated WifiFlexManager Featured

For Wifi personal security mode. It is always cumbersome to change the password whenever there is a breach in the network. and even more annoying is to distribute the passwords to the clients/guests. WifiFlexManager is a project that can change the password (with a random predefined length string) whenever the admin sends a specific IR code (through android app) and can retrieve the current password or the connected users (Through Bluetooth screen). So as a client who wants to get connected to the router, you only need to point your phone's IR towards the mbed and press a button, and the current password will be shown at your phone's screen.
