26.11 KeyRequestEvent (0x8F)
KeyRequestEvent requests the application controller to enter the passkey.
26.11.1 Functional Description
KeyRequestEvent is used as part of the pairing procedure. If MITM security and applicable IO capabilities
for the peripheral application as defined in Table 5. on page 30
are set then this event is generated. Device
configuration must be completed before KeyRequestEvent is available.
The application controller must send the SetKey command (see section 24.21 on page 124
) after receiving
this event. The SetKey command must be sent from the application controller to nRF8001 within 30
seconds of the KeyRequestEvent being received. When the SetKey command is not sent within 30
seconds the bonding will fail and the link will be terminated.
