Hello folks,

esp-idf supports handling duplicates:

• CONFIG_BLE_SCAN_DUPLICATE : This select enables parameters setting of BLE scan duplicate.
• CONFIG_DUPLICATE_SCAN_CACHE_SIZE: Maximum number of devices which can be recorded in scan duplicate filter. When the maximum amount of device in the filter is reached, the cache will be refreshed.
• CONFIG_BLE_MESH_SCAN_DUPLICATE_EN: This enables the BLE scan duplicate for special BLE Mesh scan

In my application (https://github.com/FieldTracks/JellingS ... /ble.c#L70) I want to receive duplicates to monitor the signal level over time. I'm worried, that duplicate detection may interfere with this. Unfortunately, the help-text seems to be rather brief.

Do you know:

• If duplicate detection actually interferes?
• If so: Is it possible, to set CONFIG_DUPLICATE_SCAN_CACHE_SIZE to 0?
• What does CONFIG_BLE_MESH_SCAN_DUPLICATE_EN do? By intuition, monitoring link qualities is needed in a mesh.

Thanks,
