Secure Simple Pairing IO Capability (SPP Server and SPP Master Host Mode Only)
Bluetooth 2.1 uses the Secure Simple Pairing method to authenticate devices and create an encryption key. As
a part of that algorithm, the device must state its IO capabilities. When in Serial Profile Host (master or slave),
the default is No Input/No Output and no user interaction is required; however, a device may prompt the user
to confirm the pairing process.
Keyboard Only (passkey entry) is used between a device with a display and a device with numeric keypad
entry (such as a keyboard), or two devices with numeric keypad entry. In the first case, the display shows a
6-digit numeric code to the user, who then enters the code on the keypad. In the second case, the user of each
device enters the same 6-digit number.
