Worked on the meshtastic/firmware repository to address a reliability issue affecting the ESP32-S3 USB CDC Serial Console. Using C++ and embedded systems expertise, implemented a dynamic TX timeout mechanism that switches USB CDC writes from blocking to non-blocking mode when no API client is connected, preventing main loop stalls and task watchdog reboots. The solution restored bounded timeouts during active sessions to ensure data integrity, and was validated on HELTEC_WIRELESS_TRACKER_V2 hardware across macOS and Linux. This fix reduced log write stalls from over 52 seconds to 30 milliseconds, improving CLI reliability and reducing field downtime for production deployments.

Jul 1, 2026July 2026: Delivered a reliability fix for ESP32-S3 USB CDC Serial Console in meshtastic/firmware. Implemented dynamic TX timeout switching from blocking to non-blocking when no API client is active, preventing the main loop from stalling and triggering the task watchdog. Restored normal bounded timeout during active sessions to ensure protobuf API frames aren't truncated. The fix eliminates post-disconnect task watchdog reboots, improving resilience of serial CLI and logging. Validation on HELTEC_WIRELESS_TRACKER_V2 across macOS/Linux shows reboot_count no longer increases after disconnect and log write stalls dropped from 52.4 s to ~30 ms. This reduces field downtime, improves CLI reliability, and strengthens production deployments. Key commit: 144b07986bea4e19d135a39527d587725b1dbf55. Co-authored by Ben Meadors.
