15 = SSP + IO_CAP_DISPLAY_ONLY
Note 1: SECMODE is now driven by the Simple Secure Pairing procedure included in and after v.2.1
of the BT specification.
Note 2: For SECMODE, the No I/O Capability option is equivalent to the ‘Just Works’ scenario in SSP.
Note 3: When this module interacts with a pre-2.1 device, it is unconditionally forced into legacy
pairing mode.
Note 4: Laird recommends that the reader become familiar with the SSP concept introduced in all
subsequent version of BT (post v2.1). The best introduction is to Google the phrase Bluetooth
Simple Secure Pairing.
Note 5: Contact Laird for an informal discussion if necessary.
