Major fixes and improvements to Bluetooth device management and menu navigation: **Bluetooth Device Pairing** - Fixed discovered devices not being saved as paired after connection - Only save devices to NVS when successfully connected (not just discovered) - Auto-pair discovered devices on successful A2DP connection - Update device list to show paired status immediately after connection **Critical Bug Fixes** - Fixed dangling pointer crash in NVS request/response mechanism - Was sending pointer to stack variable, now sends result value directly - Prevents crash when connecting to Bluetooth devices - Fixed use-after-free crash when clicking menu items after dynamic updates - Menu context now properly synchronized after adding/removing items - Prevents InstructionFetchError crashes in menu navigation - Fixed memory exhaustion by reducing MAX_BT_DEVICES from 20 to 8 - Prevents heap allocation failures when populating device list **Menu & UX Improvements** - "Clear Paired" button now properly disconnects active connections - "Clear Paired" button always visible when paired devices exist - GUI updates immediately after clearing paired devices - Paired devices marked with asterisk prefix (* Device Name) - Removed redundant "(paired)" suffix text - Long device names scroll smoothly when selected (3-second animation) - Refresh button preserved during menu updates to prevent crashes - Menu focus state properly maintained across all dynamic updates **Technical Details** - bt_add_discovered_device() no longer saves to NVS - Added currentFocusIndex() calls after all menu modifications - Improved clear_bt_device_list() to avoid deleting active buttons - Added bt_disconnect_current_device() for clean disconnections - Fixed NVS notification mechanism to avoid stack variable pointers 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
