Resolve Serial macro and ESP-NOW wrapper compilation errors. Preserve queue, neighbor, advert-history and Room post capacities while using qualified RTC, PSRAM and word-only IRAM storage on constrained ESP32 targets. Reduce Full infrastructure flash through lossless Room web compression, compact crypto and unused exception metadata removal.
Add focused native regressions for storage ownership, exact protocol output, OTA proofs and build policy. Keep physical flash sizes, OTA slots and RAM guard formulas unchanged.
Share nRF52 checked-record reads and command-family lookups without changing
storage formats, error protection, fleet authorization, or delegated scopes.
Use the existing bounded Merkle proof workspace for qualified ESP32 repeaters
while retaining source capacity, wire format, and every enabled feature.
Restore advert tab/CRLF delimiters and expose nested qualification build logs.
Validation: all 1932 native CI test cases; exact canonical RAK4631 Full,
Wio-E5 Mini, Station G3 Full MQTT, and Wireless Tracker Full wrappers;
linked RAK crypto/workspace checks and retained Reader code equivalence;
focused persistence, authorization, source-proof, and RAM policy regressions.
Use the committed node credential for setup WiFi, WebConfig and browser OTA. Add persistent ESP32 WiFi Companion management credentials without changing preferences layouts, revoke stale browser sessions on rotation, retain scoped save receipts, and coordinate credential changes with flash uploads. Keep external-service credentials and trusted TCP protocol compatibility independent. Update live join QR codes, failure handling and documentation.
Validated 51 native cases, 158 related host and browser methods, and serial Full V4 Companion, Station G3 Repeater, ESP32-C6 Room Server and V4 Sensor firmware builds.
Preserve observer discovery when forwarding is disabled while honoring hidden-node settings. Keep GPS power ownership paired and incorporate upstream GPS diagnostics.
Share one bounded WiFi outage and recovery schedule across MQTT, automatic NTP, Companion station ownership and WebConfig. Preserve enabled settings and foreground access while allowing normal sleep after confirmed physical shutdown.
Honor failed SDK client stops before handing off WiFi, protect clean teardown and reconfiguration, and retry transient ESP-NOW channel restoration without repeated disconnects. Add production-method, SDK failure and real sleep regressions to CI.
Validation: native MQTT/NTP/clock/reconnect suites; production power and wrapper failure tests; browser, room HTTP, OTA and combined bridge regressions; Full Heltec V4 repeater, room and companion builds with capability, flash and linked-memory checks.
Reject truncated anonymous reply paths and advert metadata before copying,
while preserving timestamp-only empty-password logins. Limit room posting to
read-write/admin ACL roles, retain inbox frames until the requesting transport
accepts them, and lock raw LittleFS traversal against concurrent writes.
Separate ISR event generations from main-loop radio state. Confirm RX/TX IRQs,
detach concrete wrapper callbacks safely, and discard inconsistent LR2021 FIFO
snapshots before rearming. Preserve bridge RX frames through packet-pool
exhaustion and bound ESP-NOW retries and missing-callback recovery. Screen RTC
register layouts without losing DS1307 startup, and ignore poisoned future
contact timestamps during clock bootstrap.
Keep the nRF52 loop stack at 8 KiB while reducing the OTA listing call chain
from 7,832 to 6,056 static bytes. Retain all target names through lossless Full
Companion compression and the canonical size optimizer. Preserve constrained
STM32 filesystems and bind corrected ESP32 UART/OLED budgets to source size
assertions. Document the separately measured preexisting W12 package limits.
Adapted for this branch from meshcore-dev/MeshCore PRs #3521, #3340, #3362,
#2062, #3503, #3038, #3534, #3544 and #3512.
Validation: 1,829 native tests; sanitized parser, inbox, LittleFS, ACL, clock,
RTC, IRQ/FIFO and bridge fault tests; 332 additional Companion cases; real
RAK4631 Full and both repeater profiles, G2 Full/standard, V3 Full and both
constrained STM32 release recipes. Radio-family compile coverage continues
separately; W12 full/portable package guards remain enforced.
Automatically split longer signed envelopes into two bounded group-data packets, reserve both before queueing, and roll back exact packet copies and retries on admission failure. Collect fragments in either order with a fixed deadline and verify the complete command before durable replay reservation and dispatch.
Raise whole-fleet protocol capacity to 230 bytes, preserve target-specific budgets and radio acknowledgement barriers, and reject rule-token and USB rescue-line truncation. Document existing app input limits and add real-signature, sanitizer, queue failure, timeout, replay, and compact-board regressions.
Enroll a private channel and publisher public key on repeaters and room servers. Local Companion fleet sends sign targeted or whole-fleet commands, with expiry, durable replay protection, and a restricted command allowlist. Preserve exact transmitted-reply barriers for secondary-radio changes, bound validation and replies, and qualify crypto, persistence, transport scope, role permissions, and compact-profile exclusions with regression tests.
Specialize repeater ACL session state, compact recent and flood records, stream Merkle proofs, and release cold OTA buffers safely. Preserve saved formats, stack sizes, table capacities, and OTA source limits. Account for lazy buffers when active and add compatibility, ARM alignment, allocation failure, and queued-response tests.
Validated six representative board/role builds, 1736 native test cases, sanitizer fixtures, and strict documentation. Document the preexisting Wio-E5 Mini flash overflow separately.
