+# Next Steps
+
+## Priority
+
+1. Investigate Protocol 2 stop handling.
+2. Complete Protocol 2 Alex support for boards with `Alex1`.
+3. Continue UI cleanup for Protocol 2 specific hardware presentation.
+
+## Immediate Issues To Debug
+
+### Protocol 2 stop crash
+
+- Re-test why the application crashes when the user presses `Stop` while working with a Protocol 2 device.
+- Re-verify why the Protocol 2 stop command may still not be correctly sent to the transceiver.
+- Check the shutdown path across:
+  - `src/DataEngine/cusdr_dataEngine.cpp`
+  - `src/DataEngine/cusdr_dataIO.cpp`
+  - `src/DataEngine/cusdr_protocol2_io.cpp`
+- Already fixed one likely cause in `src/DataEngine/cusdr_protocol2_io.cpp`:
+  - duplicate `P2 stop` send,
+  - stop without `m_running`,
+  - timer/socket signal disconnect before deletion.
+- Already fixed a second class of issues in `src/DataEngine/cusdr_dataEngine.cpp`:
+  - `DataIO` control calls now go through `QMetaObject::invokeMethod(..., Qt::BlockingQueuedConnection)`,
+  - so start/stop/init execute in the `DataIO` thread instead of the caller thread.
+- Already fixed a concrete `Protocol 2` destructor bug in `src/DataEngine/cusdr_dataIO.cpp`:
+  - `m_dataIOSocketOn == true` with `m_dataIOSocket == 0` could dereference a null pointer during shutdown.
+- Already moved `CSoundOut` deletion out of `DataIO::stop()` and into the destructor to reduce timer/thread teardown issues.
+- Pay special attention to:
+  - socket lifetime,
+  - timer lifetime,
+  - `QObject` ownership and deletion thread,
+  - repeated stop calls,
+  - `networkDeviceStartStop(0)`,
+  - `Protocol2DataPath::stop()`,
+  - `sendHighPriorityPacket(false)`,
+  - whether the command socket is still valid when stop is triggered,
+  - whether `DataIO` / `Protocol2DataPath` should be destroyed via `deleteLater()` in their own thread instead of direct delete from `DataEngine`,
+  - whether the target `P2` board expects additional shutdown packets or repeated `run = 0` frames.
+
+## Protocol 2 Functional Work
+
+- Implement proper `Alex1/BPF2/RX2` handling for boards that support a second Alex register:
+  - Orion MkII
+  - SATURN / ANAN-G2
+- Use Appendix D from `doc/openHPSDR Ethernet Protocol v4.3.docx` to map the second Alex register bits correctly.
+- Consider extending Protocol 2 capability handling beyond board defaults where discovery returns more precise information.
+- Consider support for XML/full hardware description discovery replies for board `254/255`.
+
+## UI Work
+
+- Review UI areas that still assume `Metis/Hermes` semantics internally.
+- Make Protocol 2 model/capability presentation more explicit where useful:
+  - selected model,
+  - protocol version,
+  - ADC/DDC count,
+  - Alex availability.

+# cudaSDR Protocol 2 Worklog
+
+Date: 2026-04-13
+
+This file records the Protocol 2 related work completed in this repository so future sessions can quickly restore context.
+
+## Implemented Earlier In This Session History
+
+- Added separate openHPSDR Protocol 2 transport implementation:
+  - `src/DataEngine/cusdr_protocol2_io.h`
+  - `src/DataEngine/cusdr_protocol2_io.cpp`
+- Added separate Protocol 2 discovery implementation:
+  - `src/DataEngine/cusdr_discoverer_P2.h`
+  - `src/DataEngine/cusdr_discoverer_P2.cpp`
+- Wired Protocol 2 into the existing project flow without replacing Protocol 1.
+- Updated `DataIO` so it delegates network start/stop and receive path to the separate Protocol 2 module when the selected device reports `protocolVersion >= 2`.
+- Added Protocol 2 fallback search after Protocol 1 and fixed the `Search` button path so manual search also tries Protocol 2.
+- Added initial RX-only Alex support for Protocol 2:
+  - General packet enables Alex.
+  - High Priority packet sends `Alex 0`.
+  - Filters switch automatically by band/frequency using existing Alex settings.
+
+## Implemented Today
+
+### 1. Device capability model for Protocol 2
+
+- Extended `TNetworkDevicecard` in `src/cusdr_settings.h` with Protocol 2 specific fields:
+  - `adcCount`
+  - `ddcCount`
+  - `dspClockHz`
+  - `iqFormatFlags`
+  - `phaseWords`
+  - `hasAlex0`
+  - `hasAlex1`
+
+### 2. Separate board profile helper
+
+- Added:
+  - `src/DataEngine/cusdr_protocol2_profile.h`
+  - `src/DataEngine/cusdr_protocol2_profile.cpp`
+- This helper maps Protocol 2 board ID to default hardware capabilities and human-readable model name.
+- It also provides a summary string for UI device lists.
+
+### 3. Discovery improvements for Protocol 2
+
+- Updated `src/DataEngine/cusdr_discoverer_P2.cpp` to:
+  - use board profiles,
+  - fill the new capability fields in `TNetworkDevicecard`,
+  - parse extra discovery reply fields from the documentation:
+    - byte 20: number of implemented DDCs,
+    - byte 21: frequency vs phase word,
+    - byte 22: supported IQ/endian formats.
+- Updated `src/DataEngine/cusdr_discoverer_P1.cpp` to initialize the new fields to safe defaults for Protocol 1 devices.
+
+### 4. Protocol 2 initialization based on actual device profile
+
+- Updated `src/DataEngine/cusdr_protocol2_io.cpp`:
+  - fixed General packet bit handling,
+  - enabled phase-word mode where required,
+  - selected IQ format only when the discovery flags say it is supported,
+  - used discovered/default ADC count in the DDC Specific packet,
+  - routed DDCs across ADCs,
+  - limited receiver count to hardware DDC count,
+  - used board DSP clock to compute phase words,
+  - preserved RX-only behavior.
+
+### 5. Data engine behavior for Protocol 2 devices
+
+- Updated `src/DataEngine/cusdr_dataEngine.cpp` so Protocol 2 devices:
+  - are treated as modern integrated hardware instead of legacy Mercury/Penelope stacks,
+  - automatically clamp receiver count to discovered DDC count,
+  - publish Hermes firmware field from the Protocol 2 discovery result for existing UI/status paths,
+  - enable Alex UI only if the selected Protocol 2 board profile says Alex is present.
+
+### 6. UI modernization for Protocol 2 devices
+
+- Updated `src/cusdr_networkWidget.cpp` so the device list shows a summary instead of only IP address.
+- Updated `src/GL/cusdr_oglDisplayPanel.h` and `src/GL/cusdr_oglDisplayPanel.cpp` so the top status display uses the real Protocol 2 model name instead of always showing `Hermes`.
+
+### 7. Documentation-driven corrections made today
+
+- Re-read local documentation:
+  - `doc/openHPSDR Ethernet Protocol v4.3.docx`
+- Corrected Protocol 2 board naming and assumptions from the document:
+  - board 1: `Hermes / ANAN-10/100`
+  - board 2: `Hermes / ANAN-10E/100B`
+  - board 5: `Orion MkII / ANAN-7/8000DLE`
+  - board 10: `Saturn / ANAN-G2`
+- Corrected one important capability assumption:
+  - board 2 no longer auto-enables Alex RX support, because the document indicates no Alex receive filters for that board.
+
+## Build Status
+
+- Full build completed successfully:
+  - `make -j4`
+- Output binary:
+  - `bin/cudaSDR`
+
+## Additional Fix Applied Later Today
+
+### Protocol 2 stop path hardening
+
+- Investigated the stop path after a reported crash when pressing `Stop` with a Protocol 2 device.
+- Confirmed that the shutdown flow was effectively hitting Protocol 2 stop twice:
+  - first through `DataEngine::stop() -> DataIO::networkDeviceStartStop(0)`,
+  - then again through `DataIO::stop() -> Protocol2DataPath::stop()`.
+- Updated `src/DataEngine/cusdr_protocol2_io.cpp` so that:
+  - `Protocol2DataPath::stop()` only sends the final `run = 0` High Priority packet if the path was actually running,
+  - `networkDeviceStartStop(0)` returns immediately if Protocol 2 is already stopped,
+  - `closeSockets()` explicitly disconnects timer and socket signals before deletion.
+- This removes the most obvious duplicate-stop race and reduces the chance of a timer/socket callback firing during teardown.
+- Build was re-checked after this fix:
+  - `make -j4`
+  - success
+
+### Still needs runtime verification
+
+- This stop-path fix is compile-verified but still needs validation on real Protocol 2 hardware.
+- If the transceiver still does not stop cleanly, the next thing to verify is whether the specific board expects more than a single `High Priority run = 0` packet before socket teardown.
+
+## Additional Investigation And Fixes After Emulator Testing
+
+### 1. Cross-thread DataIO control calls
+
+- Emulator testing showed that Protocol 2 startup and shutdown were still unreliable.
+- Investigation found that `DataIO` is moved to its own `QThread`, but `DataEngine` was still calling these methods directly from another thread:
+  - `sendInitFramesToNetworkDevice(...)`
+  - `networkDeviceStartStop(...)`
+  - `stop()`
+- Updated `src/DataEngine/cusdr_dataEngine.cpp` to route those calls through:
+  - `QMetaObject::invokeMethod(..., Qt::BlockingQueuedConnection)`
+- This was done so the Protocol 2 sockets and timers are manipulated from the `DataIO` thread they belong to.
+
+### 2. Additional Protocol 2 stop crash findings
+
+- User logs then showed:
+  - `QObject::killTimer: Timers cannot be stopped from another thread`
+  - `QObject::~QObject: Timers cannot be stopped from another thread`
+  - `DataEngine:: data IO thread not yet finished...`
+- This indicated there were still object-lifetime issues during teardown, not only packet-order issues.
+
+### 3. DataIO destructor bug in Protocol 2 mode
+
+- Found a concrete bug in `src/DataEngine/cusdr_dataIO.cpp`:
+  - in Protocol 2 mode, `m_dataIOSocketOn` can be true while `m_dataIOSocket` is never created,
+  - but `DataIO::~DataIO()` still dereferenced `m_dataIOSocket`.
+- Fixed destructor logic so the legacy socket is only closed/deleted when the pointer is valid.
+- This was a direct segfault candidate in Protocol 2 shutdown.
+
+### 4. Sound output teardown issue
+
+- Found that `DataIO::stop()` was stopping and deleting `CSoundOut` while Protocol 2 shutdown was already in progress.
+- Adjusted `src/DataEngine/cusdr_dataIO.cpp` so:
+  - `DataIO::stop()` no longer deletes the sound object,
+  - `CSoundOut` shutdown is deferred to `DataIO::~DataIO()`.
+- This was done to reduce cross-thread/timer teardown problems during the live stop sequence.
+
+### Current status after these fixes
+
+- Build re-checked successfully after each change:
+  - `make -j4`
+- Protocol 2 stop handling is more robust than before, but user testing still shows there may be at least one remaining shutdown/lifetime issue.
+- Most likely next area:
+  - final deletion order of `DataIO` / `Protocol2DataPath` and their child `QObject`s after `m_dataIOThread->quit()`.
+
+## Known Limitations / Remaining Work
+
+- Protocol 2 implementation is still RX-only.
+- Protocol 2 Alex support currently sends `Alex 0` only.
+- Boards with `Alex1` support such as Orion MkII / SATURN are not yet fully mapped to the second Alex register according to Appendix D.
+- Full XML or extended hardware-description discovery modes (`board 254/255`) are not implemented.
+- Wideband Protocol 2 path is still not integrated.
+- Some UI sections still conceptually assume old `Metis/Hermes` naming internally even though the visible device/model handling is now better.
+
+## Good Starting Points For Next Session
+
+- If continuing Protocol 2 work, read these files first:
+  - `src/DataEngine/cusdr_protocol2_profile.cpp`
+  - `src/DataEngine/cusdr_discoverer_P2.cpp`
+  - `src/DataEngine/cusdr_protocol2_io.cpp`
+  - `src/DataEngine/cusdr_dataEngine.cpp`
+  - `src/cusdr_networkWidget.cpp`
+  - `src/GL/cusdr_oglDisplayPanel.cpp`
+- For documentation reference, use:
+  - `doc/openHPSDR Ethernet Protocol v4.3.docx`
+- Highest value next task:
+  - implement proper `Alex1/BPF2/RX2` handling for Protocol 2 boards that support a second Alex register.
