Comment on Bluetooth tracker hidden in a postcard and mailed to a warship exposed its location — $5 gadget put a $585 million Dutch ship at risk for 24 hours

The science behind this one confuses me. Bluetooth is short range, and gps is too low power to penetrate. There’s no way a gps will get lock from inside a ship, and someone would need a compatible app and internet to relay it out.
