# Lappy v0.7.2 — provisional DRG70 and Lite support

Built for later testing with DRG70 / DRG70-C and Dragy Lite. These new receivers and this binary have not been physically tested. The current device remains on the previously installed firmware until this package is installed.

- **Find Dragy Device:** matches FD00 advertisements even without a name, and recognizes DRG/Dragy names regardless of capitalization. Explicit device selection and saved address/type are preserved.
- **25 Hz:** recognizes DRG70-family and Lite product/model names, then attempts the existing RAM-only 40 ms u-blox setting through the common writable FD01 interface. This transport is provisional for the new models; no unknown numeric Lite ID is assumed. A same-peer DRG70/Lite advertisement can supply the profile when the standard model is unavailable. A recognized DRG69 model blocks the request.
- **Measured rate:** keeps the current cadence verification and actual-rate display. A write acknowledgement alone does not establish 25 Hz. Unconfirmed/unsupported requests retain the existing stream. Missing FD01 or FD04 is tolerated.
- **Reconnect:** same-peer hints and rate setup survive direct reconnect and in-place stream repair; callbacks retain generation-token/deadline protection. Hints cannot transfer to a different address/type.

The successful DRG71 model path and request frame are retained. Timing engines, decoder, GPS quality requirements, course/PB/reference storage, SD capture/session export, persistent eight-digit Wi-Fi credentials, screen layouts, board/display behavior and memory settings are unchanged. No new preference keys, migration or receiver flash save is introduced.

Validation includes 58 production-worker scenarios, strict profile/discovery tests and historical negative control, full existing regression checks, simulator suites and linked target stack/ATT checks. These are software checks, not evidence of a real DRG70/Lite link. See the [compatibility implementation and acceptance requirements](DRAGY_COMPATIBILITY.md) and [hardware scope](HARDWARE_BENCH_v0.7.2.md).

Install the V2 `.lappy` package with the existing owner updater when ready. Close other phone clients, use **Find Dragy Device**, select the receiver, and check measured GPS Hz after streaming begins. Normal session recording and post-recording Wi-Fi export remain available. Retain the raw capture/diagnostics if the device is found but telemetry or 25 Hz does not appear.
