BLE Encryption without any

[Jusang Kim]

I'm using the nRF52DK and S132. Is it possible to encrypt a link without any pairing, bonding and authentication process ? Please show me the way how to implement with the APIs if it is. Thank you.

The peripheral/slave cannot initiate the encryption procedure, it cannot call sd_ble_gap_encrypt().

It can only call sd_ble_gap_authenticate(), and then it is up to the central device to initiate the procedure and encrypt the link (if the devices have a bond).

Thank you for reply.

Whst about the role of the central ? Is it possible to call sd_ble_gap_encrypt () without calling any pairing API functions or bonding API function in the role of central in nRF52 DK just for test purpose ?
