MeshCore DeskOS for SenseCAP Indicator D1L

DeskOS 1.2 / RC2 is the current corrective core_1_0 release for the SenseCAP Indicator D1L. Download the public v1.2.0 files from the GitHub release.

DeskOS is a standalone, dark, touch-first MeshCore client. Public binaries are built and packaged by GitHub Actions. GitHub Releases provides the complete user package, standalone ESP32 BIN files, the RP2040 UF2, checksums, and installation instructions.

Release train

Release	Purpose	State
1.0 / RC1	Published baseline, including the v1.0.1 packaging correction	Shipped/historical
1.2 / RC2	Correct channel selection and Contacts, document mobile-to-D1L parity, add actual-device screenshots, and retain explicit update/fresh-install paths	Current public release (v1.2.0)
1.5 / RC3	Fold deferred features, architecture work, localization, and technical debt into the corrected product	Planned after RC2

1.2 / RC2 product

RC2 includes the complete 1.0 product plus:

• selecting Public or another enabled channel immediately opens its chat;
• Contacts search across name, role, fingerprint, and key;
• Recent, A-Z, Role, and Signal contact sorting;
• direct Message and Manage actions for companion DMs and repeater/room detail, status, and login; and
• a read-only production framebuffer export for support and actual-device documentation.

The retained product includes Home and core navigation; Public/channel and direct messaging; contacts, Nodes, Finder, PATH/Ping/TRACE; repeater/room administration; Map/location; Wi-Fi and radio/device settings; diagnostics; and opt-in Observer/MQTT. It uses conditional SD-primary retained history with visible live-only fallback.

If prepared SD storage is unavailable, DeskOS does not silently redirect retained history to default NVS.

The exact product boundary is docs/RC2_SCOPE.md. The current mobile-to-D1L outcome matrix is docs/DESKOS_MESHCORE_FEATURE_PARITY.md.

RC2 correction status

• The #320 channel-selection root cause is fixed in 1.2.
• The #321 Contacts search/sort/action workflows are included in 1.2.
• The full current mobile baseline and explicit D1L adaptations are recorded under #322.
• The exact Actions package, attached-device update, actual-device screenshots, update BIN, full-clean BIN, and RP2040 UF2 are published with v1.2.0.

Actual-device screenshots

These are native 480x480 production framebuffer captures from the attached D1L running DeskOS 1.2.0, build e15aff9eed9feb94bef6a81f90d62ac0f9fd9610. The Map image was captured only after all 9 local SD tiles were loaded and rendered. Full capture provenance is recorded in docs/screenshots/DEVICE_1_2_CAPTURE.md.

Locations and public node labels are intentionally visible. Private messages, passwords, private keys, and admin credentials are not shown.

Deferred to 1.5 / RC3

BLE companion transport, signed OTA/update/recovery, richer QR/deep-link sharing, localization expansion, broad UI architecture work, and optional telemetry expansion follow RC2. They are tracked in docs/RC3_BACKLOG.md.

Install and use

Download the v1.2.0 package from the GitHub release, extract it fully, and follow its START_HERE.md. The repository user guide describes the current release; the SD preparation guide applies to both lines. The firmware never formats an SD card.

Every release package has two explicit ESP32 paths:

• Update: the app BIN for an existing DeskOS installation; it preserves unrelated retained flash regions.
• Fresh clean install: the full 8 MB BIN at 0x0 for a blank device, another firmware, or an intentional clean start.

The same complete RP2040 SD-bridge UF2 is used with either ESP32 path because a UF2 copy installs the full RP2040 image. Standalone BIN and UF2 assets are also published for experienced installers.

The historical 1.0 release runbook is for maintainers. End users should use START_HERE.md from the downloaded package.
