writeStream() drained the whole queue in one call - "send every packet we can". A client asking for the full config gets the node database, then the file manifest, then the packet backlog and the position replay, and none of that returns to loop(). On a full node database (120 entries) the dump runs past eight seconds, so on RP2350, where rp2040Loop() arms an 8s hardware watchdog and is the only thing that calls watchdog_update(), the board resets in the middle of the manifest. Reproducible on every connection; with a small node database the dump finished under the timeout and nothing looked wrong. Measured on a pico2_w5500_e22: last loop iteration at millis=27242, ServerAPI kept logging until uptime 35s, reset at 35.2s = 27.242 + 8.0. Take a slice instead. The PhoneAPI state machine is resumable, so writeStream() stops after STREAM_WRITE_BUDGET_MSEC and reports whether anything is left; runOncePart() then asks to be re-run immediately rather than sleeping out readStream's idle delay, so the dump keeps its throughput while loop() gets to feed the watchdog between slices. Backpressure on a retained frame still returns the normal delay - re-running at once would just spin on a full transport. Verified on hardware: 10/10 full config dumps against a node with 120 entries, no resets, dump still completes in ~8s. |

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.
