Memfault is configured for firmware type smha-91m1 and uploads through nRF Cloud CoAP (CONFIG_MEMFAULT_USE_NRF_CLOUD_COAP). The SDK collects heartbeat metrics on its internal timer and uploads data periodically (CONFIG_MEMFAULT_PERIODIC_UPLOAD), and the cloud module posts pending data on every cloud synchronization, when main asks for it with CLOUD_MEMFAULT_POST_REQUEST. Coredumps are RAM-backed. See Memfault remote debugging for dashboard setup.
