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.

/* L1 driver diagnosis: the device becomes its own access point.
|
|
*
|
|
* Ladder (docs/architecture.md): prove each layer before climbing.
|
|
* L0 SDIO control path — proven (RPC works)
|
|
* L1 wifi data path AT ALL — this file: SoftAP + DHCP + HTTP, no external network
|
|
* L2 STA to any network — phone hotspot
|
|
* L3 STA to "Outside" — the real network
|
|
* L4 gateway + Tatlock — only after L3
|
|
*
|
|
* Join DESKLOCK-DIAG (pass desklock123) with a phone:
|
|
* - association -> log + on-screen counter
|
|
* - DHCP lease from us -> IP_EVENT_AP_STAIPASSIGNED = SDIO data path PROVEN
|
|
* - http://192.168.4.1/ -> full TCP round trip PROVEN
