These standalone devices should not act as transport nodes.
Remove the config toggle, settings UI, and boot-time config peek.
Hardcode transport_enabled(false).
- Tighten transport announce rate limit from 5/sec to 2/sec
- Reduce RNS loop frequency from 200Hz to 100Hz
- Throttle LVGL rendering to 30 FPS (was unthrottled)
- Time-box TCP frame loop to 3 frames / 8ms per client
- Add 12ms global TCP budget across all clients
- Replace blocking WiFi announce delay(1500) with deferred non-blocking check
- Rotate persistData() across 3 cycles to spread file I/O
- Reduce LvNodesScreen rebuild frequency (2s → 5s, skip small transient changes)
- Bump version to 1.5.9
- Evict highest-hop unsaved nodes first when peer list is full (nearby peers survive)
- Add first-boot SD data cleanup screen before name input
- Conversation summaries cache for faster message list rendering
- Optimize message view refresh with summary-based change detection
- Streamline unread tracking through MessageStore instead of LXMFManager
- Add NTP time sync on WiFi STA connect (fixes --:-- timestamps)
- Throttle LXMF send retries to 2s intervals, increase max to 30 (~60s window)
- Restore message status re-save to disk after send completes (QUEUED→SENT/FAILED)
- Update GitHub org URLs to ratspeak
- Fix LXMF wire format: standardize on opportunistic [src:16][sig:64][content]
- Fix LXMF signature: sign(dest||src||packed) per spec, remove message_hash
- Fix MsgPack interop: handle both str and bin types for title/content
- Radio defaults changed to Balanced preset (SF9/BW250k/CR5/TX14)
- Messages screen: sorted by most recent, preview with You:/Them:, green unread dot, timestamps
- Status bar: replace LoRa/BLE/WiFi text with signal bars (green=connected, red=offline)
- Home screen: remove Unread info (shown in Messages tab)
- Contacts screen added (Friends tab)
- Identity manager: multi-slot identity support with per-slot display names
- Message store: fix peer hash truncation, SD directory creation, .bak file leak
- Settings: check for updates, active identity display, info diagnostics
- Migrate all screens to LVGL v8.4 widget system
- Non-blocking radio TX (async endPacket via LoRaInterface)
- Live TCP server switching with transient node cleanup
- Fix UI freeze during radio transmit
- Trackball long-press delete, deferred click with debounce
- Pin microReticulum to 392363c, fix list_directory API
- Fix CI build: portable include path, remove hardcoded local path
- Rewrite MessageView with word-wrapped chat bubbles, timestamps,
incoming/outgoing alignment, pixel-based scrolling
- Add IdentityManager for multi-identity support (create/switch/delete,
8 slots max, per-identity display names)
- Fix transport mode: default to endpoint (no rebroadcast) — was acting
as transport node, rebroadcasting every TCP announce over LoRa causing
5-11 second UI freezes per TX. Loop time: 11146ms → 6ms
- Add Transport Node toggle in Settings > Network
- TCP interface now drains up to 10 frames per loop (was 1)
- Reduce LoRa debug polling from 5s to 30s
Stability fixes:
- Fix message duplication (8x repeat) via messageId-based filenames
- Fix message ordering with epoch timestamps (NTP-aware fallback)
- Fix device freezes: MessageView caches messages instead of reading
disk every frame at 20fps (now refreshes every 500ms)
- Fix .bak file cascade: filter all file ops to .json only, cleanup junk
- Fix radio presets not persisting across reboots (removed force-override)
Settings redesign:
- Collapsible category navigation (6 categories with summaries)
- Enter to drill into category, Backspace to return
- WiFi network scanner with signal bars and RSSI display
- WiFi SSID/Password fields for STA mode
- TCP server preset (None / Ratspeak Hub / Custom) with host/port
- Frequency selector (868/906/915/923 MHz) and Preamble setting
- Factory reset with confirmation step
- Reboot device action
- Merged small categories (Input into Display, Actions into System)
New features:
- TCP network support for rns.ratspeak.org connectivity
- Preamble stored/applied in config and radio at boot
- Version bumped to 1.3.0
- Fix trackball completely dead: remove gpio_reset_pin() calls that
prevented GPIO interrupts from registering on ESP32-S3
- Add trackball left/right tab cycling when screen doesn't consume event
- Add NameInputScreen: Ratspeak-branded first-boot name input
- Add display name to all announces as MessagePack app_data
- Add TEXT_INPUT setting type; expose Display Name in Settings
- HomeScreen Enter key sends announce with toast notification
- Bump version to 1.2.2
- Remove boot display test (color bars + 1.5s delay)
- Show identity hashes on NodesScreen (colon-formatted, matching own identity display)
- Show node names in MessagesScreen and MessageView instead of raw hex
- Add message status indicators in chat (*/!/~ for sent/failed/queued)
- Fix LXMF send: retry Identity::recall() up to 5 times before failing
- Add LXMF logging throughout send/receive/queue drain
- Remove Alt+IJML arrow key mapping (obsolete with trackball)
- Filter own node from discovered nodes list
- Update troubleshooting docs with SetModulationParams STDBY fix
