Let the mesh timed OTA retry guard own byte-identical requests instead of the permanent bridge FIFO. Bind bridge ingress to its primary profile generation and preserve UART reflection/liveness protections. Verified a LoRa to ESP-NOW to LoRa update with outage recovery and install.
Integrate upstream 1.18.0, delayed direct ACK forwarding, zero-scope routing, Waveshare LR1121 and dynamic WiFi variants. Preserve fork chemistry-aware power management and bounded multi-interface UI; retain retry/dedup safety while adding upstream ACK delay. Qualify LR1121 band power and HP-only Morse handling with native regressions.
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.
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.
Report the upload address and required network, honor AP switches on an existing uploader, and keep delayed WebConfig cleanup from disabling OTA WiFi. Preserve actionable startup errors and account for OTA in wireless state controls.
Exercise the production OTA lifecycle and stock website console, including power-saving idle sessions, in host regression tests.
