BC127 Melody 6.1.5 - Secure Simple Pairing


I would connect a Smartphone to BC127 with a secure pairing. In this specific case, with Smartphone I want to insert a passkey in order to open an audio communication with BC127 (so I want to store a specific passkey into BC127 memory).
I’ve tried to configure BC127 with the configuration command SET SSP_CAPS but in any case the Smartphone generate a random passkey and then passed it to BC127.
Is it possible to enable the comumnication if the passkey sent by Smartphone matches with the passkey stored into BC127?
