nRF Memfault connects to Devices supporting the Memfault Diagnostic Service, and then uploads their Data - Chunks in Memfault terminology - up to the Memfault Cloud. The Memfault Diagnostic Service, or MDS, is a special GATT service which can be used to connect to and enable Chunk streaming via Bluetooth Low Energy (LE). Upon reception of these new Chunks of data, they're uploaded to the Memfault Console using the Authentication Token provided by the Device itself, through the aforementioned MDS GATT Service. Once uploaded, the the User can visualize and analyze all the uploaded data from the Memfault Console.

Note that a Device properly configured with Memfault firmware, including Authentication keys, is necessary to enable the full feature set of this application.
