### 2026-05-13 CALL 60-100 ms Repeat Result
Captures:

- `captures/rcp-buttons-call-exact-echo-delay-70ms.txt`

Observed result:
| Delay | Result |
| --- | --- |
| 60 ms | no `0x45` response |
| 70 ms | no `0x45` response |
| 80 ms repeat | no `0x45` response |
| 90 ms | no `0x45` response |
| 100 ms | no `0x45` response |
Interpretation:
- The `07 80 45 30 D0 78` response from the earlier 80 ms run did not repeat in
the 80 ms repeat or nearby 60-100 ms bracket.
- The trigger is not controlled by the simple delay between CALL high detection
and the two-frame echo pair alone.
- A more likely variable is the spacing between the host's CALL-high echo and
CALL-low echo, or the RCP's internal heartbeat/call-scan phase when the echo
pair arrives.
Next test direction:
- Keep the initial response delay fixed near the values that have produced hits
before, but vary the spacing between the two echoed CALL frames.
Tooling note:
- `scripts/serial_button_response_test.py` now supports
`--response-frame-interval`, which inserts a delay between multiple
`--response-frame` values sent for the same observed button event.

For each run, power-cycle first and use the same roughly 2 second CALL hold.
