Hi, I confuse the relationship between the 4 pairing mode in SSP with the IO capability parameter for the agent. From the agent-api.txt file, the capability parameter can have 5 values: DisplayOnly, DisplayYesNo, KeyboardOnly, NoInputNoOutput and KeyboardDisplay. I think there are only 4 pairing mode in SSP: just works, numeric comparison, out of band, and passkey entry. How the 5 IO capabilities can map to those 4 pairing modes? Thanks a lot.
