HWCDC::isPlugged() is a SOF watchdog that reads false transiently while USB is connected and working. runOnce() answered that with a 20 s sleep, and nothing wakes the thread on RX, so host traffic sat in the CDC RX ring and reached the API as a burst. Cap the sleep at 250 ms, the rate readStream() already idles at. IS_USB_SERIAL only tested ARDUINO_USB_CDC_ON_BOOT, so ARDUINO_USB_MODE=0 boards ran the same check against a USB-Serial/JTAG peripheral that is not attached to the PHY and never sees a SOF. Gate the check on IS_USB_HWCDC. Measured on tlora-t3s3-v1, 900 s of 1 Hz ToRadio/FromRadio round trips: before 12 stalls, rtt_max 19.96 s, console asleep 26.4% of wall time. After 0 stalls, rtt_max 0.147 s, p50 unchanged at 0.028 s. Fixes #11864
Meshtastic Firmware
Overview
This repository contains the official device firmware for Meshtastic, an open-source LoRa mesh networking project designed for long-range, low-power communication without relying on internet or cellular infrastructure. The firmware supports various hardware platforms, including ESP32, nRF52, RP2040/RP2350, and Linux-based devices.
Meshtastic enables text messaging, location sharing, and telemetry over a decentralized mesh network, making it ideal for outdoor adventures, emergency preparedness, and remote operations.
