Hi all I need LE secure authentication to be enabled on the device (nRF52 DK). Enabled Legacy and LE secure authentication in syscfg.yml and added *BLE_GAP_EVENT_PASSKEY_ACTION *code (means calling *ble_sm_inject_io*()) in the *bleprph_gap_event*(). The Legacy authentication is working as expected, but if we select LE secure authentication *BLE_GAP_SEC_STATUS_PDU_INVALID *is showing in nRF Connect Desktop application.
Please anyone mention if there any other configurations or code I need to add, for LE secure authentication to work. Regards Jain
