stolen from Zephyr main:
1. Issue StopTimerOnPreamble=1 before SetRxDutyCycle so the chip's
timer is not reset on every preamble detect (per §13.1 of the
datasheet). Without this, duty cycle effectively never sleeps in
noisy RF and current draw spikes.
2. On IRQ_RX_TX_TIMEOUT during duty-cycle RX, re-arm via
sx126x_restart_rx() instead of falling through to set_sleep().
The old path silently killed duty cycle after the first preamble
false-positive.
3. On recv_duty_cycle(NULL) cancel, wake the radio before issuing
SetStandby — BUSY stays asserted during the sleep phase and the
standby command was being dropped.
Also adds a dc_timeout_restarts atomic counter incremented on the Fix 2
path, exposed end-to-end: sx126x_ext.h accessors → LoRaRadioBase vtable
→ SX126xRadio override → CommonCLICallbacks → RepeaterMesh. Query via
`get dc.restarts` on the repeater CLI; cleared by `clear stats`. High
values indicate a noisy environment or a too-loose preamble threshold.
(+increase ESP BT stack because future zephyr pin advance will trip that mine)
- only two leds, red and blue
- fix pin definition and polarity for leds
- remove unmapped pins
- swap buttons, so they match datasheet and marking on buttons
- flood retransmit jitter now capped at min(2000ms, 6·airtime) instead of
fixed 2000ms — spreads tighter at SF7, unchanged at SF8
- reactive per-dupe backoff cap now min(2000ms, 12·airtime), keeps
semantic of "push past ~12 relay slots"
- contention ring 16 → 24 for 50-neighbor hilltops
- companions passively track heard floods (warms EMA without forwarding)
and spread their own TX by up to min(1000ms, 3·airtime), hopefully
fixing repeaters missing companion's first transmission
config cleanup:
- move BLE TX buffer bumps (ACL_TX=12 etc.) from zephcore_common.conf to
esp32_common.conf — the Espressif blob needs them, nRF doesn't, and
the bumps were overflowing nRF52840 RAM
- remove CONFIG_ZEPHCORE_MAX_CONTACTS=510 overrides from 5 nRF52840
companion boards; Kconfig default of 350 fits with comfortable margin
(wio prod: 91% → 79% RAM)
This adds automatic builds via Github Actions. A new release will be
created when a new commit is pushed to the "master" branch. The
description for the release will be taken from the latest commit, in the
case of a merged pull request that will be the merge commit.
To add new boards for building, extend the arrays in the build.sh script.
To start, I included all boards from `supported_boards.md`.
