PROFILE

Clive Blackledge

Worked on the meshtastic/firmware and meshtastic/meshtastic repositories, delivering three features over three months focused on mesh networking and embedded systems. Developed a Traffic Management Module in C++ that introduced packet deduplication, rate limiting, and memory optimizations for NRF52 devices, improving routing reliability and efficiency. Enhanced router-to-router communication by preserving hop limits for favorite routers, updating core routing logic to support scalable mesh deployments. Contributed technical writing by authoring a detailed blog post on zero-cost hops, clarifying mesh concepts for onboarding and external engagement. Emphasized robust unit testing, protocol buffers integration, and cross-variant support to ensure maintainable, reliable code.

In March 2026, delivered a Traffic Management Module for packet forwarding that introduces position deduplication, rate limiting, and unknown packet filtering to improve routing reliability and memory efficiency. Achieved targeted memory optimizations on NRF52 devices, reducing per-entry memory to 12 bytes and total cache usage to ~12 KB, enabling larger-scale NodeInfo caching. Hardened NodeInfo response handling and cache behavior, updated hop logic, and ensured seamless activation across variants (including portduino) with consistent traffic management enablement. Implemented comprehensive unit tests (including mock classes) to prevent regressions, expanded logging, and refined configuration checks for better observability. Updated dependencies (protobuf submodule) and improved cache allocation/destruction to properly manage PSRAM vs heap, reducing leaks and fragmentation. Overall impact: higher throughput, lower latency under load, and more predictable behavior in dynamic networks, delivering tangible business value for operators and developers.

September 2025 monthly summary for meshtastic/firmware focused on delivering a performance-enhancing feature and stability improvements. Implemented preservation of hop limits for router-to-router communication, emphasizing favorite routers to reduce hop-count depletion and extend effective communication range. The feature updates the FloodingRouter and NextHopRouter to conditionally decrement hop limits based on device role and previous relay, enabling more efficient mesh operation.
