CrumBLE v4.5.3

CrumBLE v4.5.3

Fixes

• Bluetooth Setup now reachable from Sync & Network in Settings. Previously you had to open a book before pairing a page-turner remote; first-time users can now bond their device from cold-boot Settings.
• BT scan no longer flashes back to Home on tight heap. The silent-restart-to-recover heap path was correctly firing when scan needed more contiguous heap, but the post-reboot dispatch was snapping the target value to 0 (Home). Fixed the bound so the device lands back in BT Settings on the freshly-recovered heap and can complete the scan.

Web UI

• LAN-OTA upload retry cap 8 → 16 for users on weaker WiFi.
• Install-handoff timeout + retry. Previously a successful upload could hang at 100% in the install-firmware handshake (WS cleanup race). Now has a 3s deadline + 5-attempt retry loop, so reaching 100% reliably progresses to Installing.

Misc

• Stuck "Loading" popup on non-Flow Home themes after fresh-flash boot now clears automatically without needing a button press.
