4 day class covering the full Bluetooth Low Energy (BLE) protocol stack from the bottom (PHY) up to the top (GATT).

Backdooring popular encryption to fight crime is such a silly idea I can sum up the argument in one sentence: criminals will set up and use the non-backdoored version making everyone else less secure.
