Hi,

It looks to me like you are comparing a empty FDS flash page on the left side, and a populated FDS page on the right side. Therefore it is tempting to believe that the error you are seeing is because you are trying to re-pair with a device (phone) that was already paired. That is not allowed by the peer manager by default. If that is the problem then you should either delete the bond on the nRF side as well before attempting to repair, or you should configure the Peer manager to allow repairing. The latter can be done by setting .allow_repairing = true in the handling of the PM_EVT_CONN_SEC_CONFIG_REQ event in your application.

Br,

Einar
