PROFILE

Wessel

Worked on meshtastic/firmware and Meshtastic-Android, delivering targeted improvements in reliability, security, and sensor accuracy for mesh networking devices. Enhanced the Store Forward subsystem by adding detailed hop and transport tracking, improving message traceability using C++ and embedded systems expertise. Addressed network reliability in Meshtastic-Android by updating socket timeout logic in Kotlin to prevent blocking. Strengthened firmware security by zeroizing public key arrays and refining MQTT transmission logic. Improved RF receive performance and sensor voltage readings through low power design and hardware-specific calibration. The work demonstrated a methodical approach to firmware development, focusing on robust, maintainable solutions for real-world deployments.

Mar 1, 2026

March 2026: Firmware fixes to sensor power enable and sensor voltage readings for NTC/LUX sensors in meshtastic/firmware. Reclassified P0.04 as a sensor power enable GPIO, corrected use from ADC input, and switched read path to BATTERY_PIN with ADC_MULTIPLIER for accurate voltage calculations. Cleaned up pin naming and init flow for T1000-E/S variants, improving temperature reading reliability and sensor stability.

February 2026: Security hardening, messaging reliability, and RF RX performance improvements across meshtastic/firmware. Delivered key security fix to zeroize public key arrays; corrected MQTT transmission logic to respect sender's PSK preference; implemented comprehensive RF RX enhancements including deep-sleep power management, LDO startup stabilization, board-specific RX tuning, and AGC reset for SX126x/LR11x0. Impact: reduced packet loss, improved wake-on-packet RX (~17 dB) with a trade-off of ~6.5 mA extra deep sleep current; these changes strengthen security, reliability, and overall user experience for mesh networks.

Nov 1, 2025

Month: 2025-11. Delivered a targeted improvement to the Store Forward (S&F) subsystem in meshtastic/firmware, focusing on transport and hop information tracking to improve traceability and reliability of message delivery. Implemented data extensions and storage for hop, MQTT, and transport mechanism details, enabling storing and transmitting detailed transport and routing information for S&F messages. This supports better debugging and end-to-end visibility for field deployments.
