DeskOS MeshCore 1.7.9

DeskOS 1.7.9 repairs Wi-Fi, Bluetooth companion mode, and MQTT Observer
coexistence on the SenseCAP Indicator D1L.

What changed

  • Wi-Fi plus Bluetooth: the Bluetooth stack and Observer worker now place
    their larger allocations in PSRAM, preserving scarce internal memory for
    Wi-Fi and the radio.
  • Bluetooth companion mode: enabling Bluetooth no longer starves or drops
    an active Wi-Fi connection.
  • Reliable Observer startup: secure MQTT waits for network-validated time
    before creating signed broker credentials or opening TLS connections.
  • Bounded retries: Observer startup and reconnect work yield between
    attempts instead of repeatedly consuming the UI and networking loop.
  • Lower connection pressure: unused Bluetooth services and oversized
    controller pools are removed, retained route/Observer buffers live in
    PSRAM, and the two secure broker handshakes start sequentially.
  • Useful broker diagnostics: Observer status now distinguishes broker
    rejection, TLS failure, and socket failure without exposing credentials.
  • Two default brokers: Observer continues to publish to both
    mqtt1.meshcore.ca and mqtt2.meshcore.ca, with the custom broker option
    unchanged.
  • Existing 1.7.8 fixes retained: recent adverts, message timestamps,
    progressive maps, and the top-button flood advert remain included.

Safety

  • Observer remains opt-in and the D1L remains a non-forwarding MeshCore
    client.
  • This release does not add automatic public RF traffic.
  • Broker credentials, private keys, passwords, contacts, and message contents
    stay out of status and diagnostics.
  • The app-only update preserves identity, channels, contacts, settings,
    message history, radio settings, SD contents, and RP2040 firmware.

Recommended update

Existing DeskOS users should install the preserving update image at 0x20000.
Use the full 8 MB image only for a fresh or intentionally erased device.
