Two things, both found by looking rather than by being told. A Heltec V4-R8 crash dump from beta_77 decodes to a data race in the Arduino core's Wi-Fi event list. Correcting for the unwinder mangling Xtensa return addresses, the event task was inside _eventCallback copying a WiFiEventCbList entry, iterating the callback vector, while loopTask was still in setup() inside _M_realloc_insert growing that same vector through WiFi.onEvent(). The reallocation frees the buffer the event task is walking, so it then calls through a dangling function pointer, which is the garbage program counter in the dump. Neither side locks, and the vector is the core's, not ours. What is ours is the ordering: both handlers were registered AFTER the stack was started, one of them after WiFi.begin(), so a STA_DISCONNECTED arriving during boot association lands in the window. A failed first association is ordinary, which is why this happens at all. Both now register before WiFi.mode(WIFI_STA), so nothing mutates the vector once events can flow and the race is impossible rather than unlikely. This is a crash during setup(), so on an unlucky unit it is a bootloop, which makes it worth more than its single report. The moved handler drops its WIFI_DEBUG_PRINTLN tracing, which comes from a header not in scope that early. The prints compile to nothing in a release build and the reconnect flag they accompanied is unchanged. Separately: the location-privacy setting shipped in beta_77 on the wrong page. It was inside the Sensors section rather than GPS, because the insertion was anchored to a comment belonging to the Sensors block, and that section is described in its own code as V4-with-kit only. So on most boards it was not reachable at all, which is exactly what two people reported: they went looking and correctly concluded it was not there. It now sits in the GPS section, is named "Location privacy" rather than "Position in adverts" (nobody searching for a privacy control scans for the word "adverts"), and offers four buttons instead of a cycling one, so every option and the current choice are visible without touching anything. Given the failure here was discoverability, showing the most without interaction is the point. All nine S3 envs and both ESP32-P4 targets green. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
wadamesh.com infrastructure
Distribution stack for wadamesh: a VPS nginx origin behind Cloudflare.
tiles.wadamesh.com →CF (HTTP, edge-cached) → nginx → OpenStreetMap / OpenTopoMap
firmware.wadamesh.com →CF (cache bins) → nginx → /srv/wadamesh/firmware
flasher.wadamesh.com →CF (HTTPS) → 301 → wadamesh.com
wadamesh.com →CF (HTTPS) → nginx → /srv/wadamesh/site
Map tile styles. The default /{z}/{x}/{y}.jpg route serves OpenStreetMap
(the firmware default). An opt-in OpenTopoMap topographic style is served from
/opentopo/{z}/{x}/{y}.jpg (explicit OSM alias at /osm/...); the device requests
it only when the user enables Map → Options → Topographic map. Legal: OpenTopoMap
map tiles are © OpenTopoMap (CC-BY-SA) over © OpenStreetMap contributors
(ODbL) + SRTM — the touch UI shows that attribution when topo is active, and the
14-day disk cache keeps each tile hitting OpenTopoMap at most once per fortnight
(their tile-usage policy asks for a contactable UA + caching, both of which the
transcode service provides). Deploying the topo routes = update
tiles.wadamesh.com.conf + tile-transcode.py, then
systemctl restart wadamesh-tile-transcode && nginx -t && systemctl reload nginx
and purge the Cloudflare cache for tiles.wadamesh.com/opentopo/*.
The firmware fetches tiles + the update-check over plain HTTP (on-device HTTPS isn't viable — mbedTLS needs ~30 KB heap, only ~5 KB is free post-Wi-Fi), so the tile + firmware hosts must stay reachable over HTTP. Cloudflare provides the edge cache, HTTPS for the flasher, and hides the origin IP (so no IP lives in this repo or the firmware).
1. VPS (origin)
sudo apt install nginx
sudo mkdir -p /srv/wadamesh/firmware/releases/TOUCH /var/cache/nginx/wadamesh-tiles
sudo cp deploy/nginx/tiles.wadamesh.com.conf /etc/nginx/sites-available/
sudo cp deploy/nginx/firmware.wadamesh.com.conf /etc/nginx/sites-available/
sudo ln -s /etc/nginx/sites-available/tiles.wadamesh.com.conf /etc/nginx/sites-enabled/
sudo ln -s /etc/nginx/sites-available/firmware.wadamesh.com.conf /etc/nginx/sites-enabled/
sudo nginx -t && sudo systemctl reload nginx
2. Cloudflare
- DNS:
A/AAAArecords fortiles,firmware,flasher,@→ the VPS IP, all Proxied (orange cloud). - SSL/TLS: mode Flexible (CF↔origin HTTP) is enough since the origin is
HTTP-only. Do NOT enable "Always Use HTTPS" on
tiles.orfirmware.— the firmware needs plain HTTP there. - Cache Rules:
tiles.wadamesh.com/*→ Eligible for cache, Edge TTL ~14d.firmware.wadamesh.com/releases/*/*.bin→ cache, Edge TTL ~1d.firmware.wadamesh.com/releases/TOUCH(the listing) → short TTL (~60s) or Bypass, so new releases appear promptly.
3. Publishing a release
From a wadamesh checkout (builds both boards, refreshes the listing, rsyncs up):
WADAMESH_VPS=user@your-vps scripts/release.sh beta_2
The on-device check GETs http://firmware.wadamesh.com/releases/TOUCH, finds the
highest beta_<N>, and (once OTA-over-Wi-Fi is re-enabled) pulls
…/releases/TOUCH/beta_<N>/<board>.bin.
Done
- Web flasher ✅ — the guided install page at
wadamesh.com, served fromdeploy/site/and published byscripts/deploy-site.sh(esp-web-tools / Web Serial, per-board install buttons + .bin downloads, manifests generated per release byscripts/build/gen-flasher-meta.pyinto the/latest/and/latest-beta/feeds thatrelease.shrefreshes each publish). flasher.wadamesh.com301-redirects to the apex (seedeploy/nginx/flasher.wadamesh.com.conf) — it is an alias, not its own page.deploy/flasher/is the original standalone flasher page. No deploy script publishes it —deploy-site.shshipsdeploy/site/only — so it is effectively an offline/local copy kept in parity by hand. Retire it or wire it into a deploy target; until then, treatdeploy/site/index.htmlas the only install page users can reach.
TODO before public launch
- Re-enable OTA-over-Wi-Fi in the firmware (currently it version-checks then defers to manual flashing).
- Flip
wadameshrepo public = launch. - Decide tile-proxy sharing: dedicated
tiles.wadamesh.com(this config) vs reusing the meshcomod proxy.
Never commit the VPS IP, SSH keys, or
WADAMESH_VPS. Cloudflare fronts the origin; the deploy target is supplied via the environment at publish time.
