Device Networking & Provisioning

Trace first-command latency across AP buffering, DTIM and client sleep policy, then measure energy and responsiveness together.

Design roaming decisions around fresh BSSID candidates, hysteresis and application continuity, with explicit k/v/r boundaries.

Keep WPA-PSK passphrases and raw keys distinct, map each backend correctly, and reject input errors before association.

Preserve SSID bytes through scanning, Unicode display, provisioning transport and persistence, with reproducible boundary fixtures.

Compare deployment region, per-PHY channel flags and AP settings to explain why an embedded device cannot discover a network.

Diagnose missing hidden SSIDs with scan evidence, exact manual input, bounded directed probes and channel-aware validation.

Compare ESP32 SoftAP and BLE provisioning by phone workflow, security, memory and recovery needs, with practical prototype decision gates.

Plan an ESP-IDF 6 provisioning migration with explicit dependencies, API mappings, security checks and older-app regression evidence.

Design ESP32 provisioning recovery for wrong passwords, router changes and power loss using layered logs, state transitions and acceptance cases.

Define DHCP client and server roles by interface, then test leases, recovery, address conflicts and setup-network isolation before delivery.
