| ESP-NOW TX path delivers reliably | COM9: `c6_espnow: tx#101 (fail=0) rx#0 (match=0)` over ~15 s — 100% TX success rate at the configured 100 ms cadence |
| Build green for both targets | `firmware-ci.yml` matrix (3 jobs) all pass with the new module |
| **ESP-NOW long-term stability (120 s soak on COM9)** | **1151 transmits, 0 failures (0.00 %), 9.6 tx/s sustained, no crash/reset in 2 min.** Boot detector saw exactly 1 `app_main` call. Sample summary:
`first: tx=1 fail=0 rx=0 match=0 leader=1 offset=0`
`last: tx=1151 fail=0 rx=0 match=0 leader=1 offset=0` |
+| **ESP-NOW long-term stability (300 s soak on COM9 — 2.5× the 120 s sample)** | **2951 transmits, 0 failures (0.0000 %), 9.83 tx/s sustained, no crash/reset in 5 min.** 60 counter samples, 1 `app_main` call. Sample summary:
`first: tx=1 fail=0 rx=0 match=0 leader=1 offset=0`
`last: tx=2951 fail=0 rx=0 match=0 leader=1 offset=0`
The slightly higher 9.83/s vs 9.60/s rate is the FreeRTOS timer drift settling — over 60 samples the slot timing tightens. Still 0 failures across both soaks. |
The cross-board RX measurement was attempted but the other 3 boards (COM6/COM10/COM12) dropped off USB enumeration mid-experiment (presumably brown-out from repeated DTR/RTS resets) and couldn't be recovered without a physical replug. **Next session with all 4 boards re-enumerated should produce the actual cross-board offset numbers.** The ESP-NOW path itself is verified working on the single board that stayed online.
