…d thermal risk Lower the STA auth threshold from WPA2_PSK to WPA_PSK so routers running WPA/WPA2-mixed compatibility mode aren't rejected with WIFI_REASON_NO_AP_FOUND_IN_AUTHMODE_THRESHOLD (reason=211), and log the disconnect reason/rssi instead of retrying blind. Also document the thermal risk of running this firmware's continuous-radio, tier-2 DSP pipeline on coin-sized clone boards (ESP32-S3-Zero, SuperMini) with minimal PCB copper and budget regulators, after a field report of three such boards failing to power on following a normal session.

Summary
WIFI_AUTH_WPA2_PSKtoWIFI_AUTH_WPA_PSKso routers running WPA/WPA2-mixed compatibility mode (common default on many consumer routers) aren't rejected withWIFI_REASON_NO_AP_FOUND_IN_AUTHMODE_THRESHOLD(reason=211). Also log the disconnect reason + RSSI instead of retrying blind, so this is diagnosable from serial output next time.firmware/esp32-csi-node/README.md, the repo'sCLAUDE.mdhardware table, and theruview-hardware-setupskill (so an AI agent flashing on someone's behalf asks about board form factor and warns proactively).Why
Hit both issues live while onboarding a fresh 3-node deployment:
reason=211, traced it to the router's WPA/WPA2-mixed mode being rejected by the strictWPA2_PSKthreshold.WIFI_PS_NONE) plus a full edge DSP pipeline (edge_tier=2) continuously, with no duty-cycling. Full-size dev boards (DevKitC-1, XIAO) have the copper pour/thermal mass to handle that; coin-sized clones with minimal PCB copper and budget regulators may not. Nothing in the docs warned about this before someone (or their AI agent) walks away from a board assuming any ESP32-S3 handles sustained full-load operation.Full incident writeup + follow-up ideas (duty-cycled mode for compact boards, runtime thermal check) in #1289.
Test plan
espressif/idf:v5.4Docker buildwifi-densepose-sensing-serverover UDPreason=211before the fix, and connects cleanly aftercargo test --workspace --no-default-features/ firmware CI as this only touchesmain.c+ docsDocs portion addresses #1289 — thermal follow-up items in that issue remain open.
