// wifi_cfg_dualmode.c — ESP-IDF v5.3.x

// Listens for CFG/END Wi‑Fi config on BOTH UART(console/COM) and USB‑Serial/JTAG concurrently.
|
||
// - UART path uses stdio (fgets on stdin) — works with /dev/ttyUSB*
|
||
// - USB path uses driver API (usb_serial_jtag_read_bytes / write_bytes) — works with /dev/ttyACM*
|
||
// - Tolerates ESP_ERR_INVALID_STATE on repeated inits
|
||
// - Supports DHCP or static IP, persists to NVS, applies immediately
