# Default sdkconfig overrides for the Quantumancy sensor node.
#
# These are seed values applied when `idf.py set-target esp32p4` generates the
# real `sdkconfig` (which is machine/toolchain-specific and NOT committed —
# see .gitignore). UNVERIFIED: nobody has run `idf.py build` against a real
# ESP-IDF install for this project, so treat these as reasonable, standard
# starting points rather than confirmed-working values.

CONFIG_IDF_TARGET="esp32p4"

# --- Wi-Fi via the onboard ESP32-C6 co-processor (esp_wifi_remote/esp_hosted) ---
# The ESP32-P4 has no integrated Wi-Fi radio. On the target hardware
# (Waveshare ESP32-P4-Module-DEV-KIT), an ESP32-C6 co-processor is wired to
# it over SDIO — 7 fixed pins: CLK=18, CMD=19, D0=14, D1=15, D2=16, D3=17,
# RESET=54 — and esp_hosted/esp_wifi_remote handle those transparently once
# configured; wifi_manager.c's esp_wifi_init()/esp_wifi_start() calls need
# no changes. These CONFIG values match Espressif's own reference
# ESP32-P4-Function-EV-Board, whose SDIO pin assignment is identical to
# Waveshare's board (verified against two independent sources) — still,
# this is the single most important thing to confirm against the physical
# board before flashing, since it was never run against real hardware.
