Root cause of the dead data path (assoc/scan/RPC fine, zero data frames): esp-hosted 1.4.x is formally incompatible with IDF 5.5 (esp-hosted-mcu#47) and the factory C6 slave firmware was ancient (couldn't even answer a version RPC). Waveshare's examples pin 1.4.* — do not follow them. Fix: - host: espressif/esp_hosted ^2.12 (+ esp_wifi_remote 1.6) - slave: 2.12.11 network_adapter.bin embedded in the app (c6_ota.c streams it to the C6 over the SDIO RPC channel at boot when the reported version is < 2.x; ~10s, no wires, idempotent) - RAM diet for hosted 2.x's footprint (MEMPOOL_PREFER_SPIRAM, reduced WIFI_RMT buffers) — without it internal SRAM famine boot-loops in xTaskCreateStaticPinnedToCore before app_main - conservative 20MHz SDIO clock for first verified data path Verified on hardware: DHCP lease (even that healed), 8/8 pings to router and tower-of-joy at 1-5ms, WebSocket to the gateway connected, device registered at /devices as desklock-p4 with fw version. Also: wifi_diag.c L1 SoftAP diagnostic mode (DESKLOCK-DIAG) with review fixes, boot ping ladder in net.c, static-IP fallback, face_status() line, docs for the whole failure taxonomy.
