Secure Simple Pairing Io Capability (Spp Server And Spp Master Host Mode Only) - Motorola LI4278 Product Reference Manual

Secure Simple Pairing IO Capability (SPP Server and SPP Master Host Mode Only)

Parameter # 911
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 is used to
show 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.
NOTE This option should be used to connect to an Android tablet.
No Input/No Output: Least amount of security (may not be acceptable for some devices).
•
Keyboard Only: Higher level of security.
