Features

Current beta and planned capabilities

The Android 8.0+ public beta includes account-authorized cellular PTT, and exact verified CJ-1 hardware adds local RF features. Offline mesh, automatic switching, and broader radio gateways remain in development.

Current status: Link’d DMR 0.2.65 Code68 is an approved or invite-only public beta for Android 8.0 and newer; there is no iPhone app. All seven reviewed CJ-1 tracks are included: Dispatcher Lite expansion, manual RF/Cellular handoff, bounded direct Nearby coordination, better physical controls, Bluetooth PTT and audio, signed configuration handoff, and privacy-safe field diagnostics. Automatic path selection and Nearby remain safely unavailable when their production adapters are not configured. Verified CJ_1UV hardware with a supported DMR003N.UV4P.V### live firmware layout can test the exact-device RF path after selector 01 verification. This beta is not an emergency-communications service and makes no multi-hop claim.

  • Cellular PTT

    Approved-beta radio-style push-to-talk over Wi-Fi, 4G, or 5G on Android 8.0+ with readable operating states and server-enforced floor control.

  • Direct Nearby Coordination

    Code68 includes bounded direct-device queues and reconciliation, but the surface stays unavailable until a reviewed production transport adapter is configured. Multi-hop is not claimed.

  • Exact CJ-1 Radio Home + RF

    A verified exact CJ-1 adds the compact radio home and can use the local DMR and analog RF beta. Phone-to-radio gateway bridging remains under validation.

  • Site, Team, and Channel

    Authorized Business managers organize operations by Site and Team. Each Team currently receives exactly one private cellular Channel.

  • Multi-Industry Operations

    Security companies are the lead use case, with the same operating model available to approved hospitality, construction, warehouse, event, education, transportation, retail, and other pilots.

  • Security-First Relay

    Unverified communication paths stay unavailable instead of pretending a transmission succeeded.
