Revert b9e20b2662 because it causes app-side configuration reads to hang on GAT562.
This restores the previous Meshtastic BLE timing/notification behavior and also drops the cross-target compatibility adjustments that came with that commit.
Adjust the Meshtastic BLE transport timing on nRF52, retain pending FROMNUM notifications, and defer local admin/self replies to reduce request/response races during Android settings flows.
Also make the shared chat/UI code compile across non-nRF targets by gating RTOS and Arduino-only helpers and by updating the team page layout to the current page profile fields.
Note: this does not resolve the gat562 Meshtastic Android settings progress bar issue yet; the BLE/admin response path is improved and instrumented, but the root cause of the stuck loading state remains unresolved.
Refactor the GAT562 board runtime by extracting dedicated GPS and input runtime components and routing config application through a focused runtime apply service.
Narrow the nRF52 BLE manager dependencies, rework the Meshtastic BLE transport to better match the Android client handshake, and harden the FromRadio/FromNum flow with improved staging, read pacing, diagnostics, and stack-safe config snapshot generation.
Also repair repository text encoding issues in docs and UI comments, and add Meshtastic BLE timing documentation to capture the expected Android/firmware interaction model for future debugging.
Bundle the current workspace changes into a single checkpoint covering the in-progress shared UI, settings, and GAT562 runtime work.
What this includes:
- add the APRS asset source and image resource currently used by the shared UI asset set
- extend the shared System/settings flow so vibration and screen brightness can be surfaced through the device runtime and settings UI plumbing
- update the mono 128x64 runtime and the GAT562 platform bindings so the new settings controls are available in the GAT562 experience
- wire the ESP runtime/startup helpers needed to support the same device-runtime settings path on the ESP side
- persist the GAT562 self GPS position into the node store during core service updates so a device that already obtained a fix can retain its own last known position across reboot
- add an explicit node-store flush interface and implement it in both the nRF52 and ESP Meshtastic node-store backends so critical self-position updates can be forced to persistent storage immediately instead of waiting for the normal debounce window
- keep the existing debounced persistence behavior for ordinary node-store churn while allowing targeted immediate flushes for data that would otherwise be easy to lose during restart or power loss
- migrate ESP board-specific implementations and runtime adapters into boards/*
- continue GAT562/Tab5/UI runtime alignment across app and board layers
- sync BLE and runtime integrations, and apply repository clang-format rules
Integrate Fusion Pixel 8px as the NRF mono UI font stack and switch the mono runtime to a dedicated MonoFont/TextRenderer path that can render ASCII, CJK, and symbols from one asset set.
Add the generated NRF font assets and generator script, including the compact font format with per-glyph advance support, and fix the BDF bitmap parsing bug that previously produced blank ASCII glyphs on device.
Move the LVGL Noto CJK font asset out of shared modules into the ESP-specific platform tree and update the related build/config references so the ESP-only font boundary is explicit and NRF does not compile the LVGL asset by accident.
Update the mono UI runtime to use the new renderer, normalize major menu and title labels to uppercase, and wire the GAT562 UI runtime to the Fusion Pixel font.
Fix the core mesh adapter router so Meshtastic and MeshCore backends can coexist without overwriting each other, and ensure active protocol selection is applied before mesh config changes are pushed into the runtime.
Improve GAT562 runtime diagnostics by mirroring debug output to both Serial and Serial2, logging startup radio configuration, and logging raw RX packets with RSSI/SNR so radio-path issues are visible during bring-up.
Relax SX1262 receive polling so it no longer hard-gates RX handling on DIO1 state alone, avoiding a failure mode where the board appeared alive but never delivered packets into the receive path.
Align the NRF Meshtastic adapter with the working ESP behavior for channel handling: use the default expanded public PSK for an unconfigured primary channel, compute channel hashes from the active preset name or Custom label instead of a hard-coded Primary string, and apply the same logic to self-announcement/NodeInfo packets.
Add protocol-layer Meshtastic RX diagnostics for parse, decrypt, decode, text queueing, app-data queueing, unknown-channel, and dedup events to make packet flow visible while validating interoperability.
Fix early duplicate handling for relayed packets so the first valid packet is still delivered into text processing while later relays are correctly suppressed, which restores Broadcast conversation creation and message visibility in the CHATS page.
- extract Meshtastic and MeshCore phone/business flows into shared core_chat BLE cores with owner hook seams for ESP and nRF backends
- replace nrf-specific lite adapters with board/platform adapters that consume shared cores and shared storage contracts
- extend nrf Meshtastic radio path with packet history dedupe, flooding rebroadcast, route discovery/traceroute responses, routing ACK/error handling, observed relay learning, retransmit queueing, and next-hop persistence
- persist nrf device identity and node metadata more explicitly, including next-hop state and node-id initialization support
- move nrf chat/contact/blob storage further toward InternalFS-backed persistence and update contact/node store behavior accordingly
- wire gat562 protocol/app facade pieces to the concrete nrf stores/adapters and add supporting app time-sync hooks used by platform runtimes
- add owner-hook split files and planning/status docs to document the ongoing alignment with the reference meshtastic-firmware multi-platform structure
