Native USB host (ESP-IDF USB Host library + usb_host_hid): enumerate and talk to USB HID devices (mice, keyboards, gamepads, vendor HID) from an ESP32-S2/-S3/-P4
Point-to-point UDP datagram transport for ESP-IDF v6.0.x. One socket, one peer, one stream: a 12-byte header with sequence number and session, strict validation of every received datagram, zero-copy send and receive, and a receive timeout that never ends early. No tasks, no callbacks, no buffering, no retransmission: it reports loss and restarts, you decide.
