From fe6aa9663d4cdabdc6e71db6068f8cd9e3739ffe Mon Sep 17 00:00:00 2001 From: Your Name Date: Tue, 19 May 2026 13:14:48 +0530 Subject: feat: WiFi beacon price discovery via Vendor IE (two-board verified) Price discovery allows TollGate ESP32 boards to advertise their per-step price via WiFi Vendor-Specific Information Elements (OUI 0xC0FFEE) in beacon and probe response frames. Nearby boards passively scan and build a market view of competing TollGates without requiring internet access. Features: - beacon_price.c/h: 26-byte packed Vendor IE payload (price, step, metric, mint_hash, geohash, npub_hash), injected via esp_wifi_set_vendor_ie() - market.c/h: Passive WiFi scan receiver, vendor IE callback parsing, BSSID-correlated market entries, effective price ranking - GET /market API endpoint: JSON market snapshot with discovered entries - AP-only services: beacon + market + API start on WIFI_EVENT_AP_START, independent of STA connectivity - STA reconnect fix: 2s delay between retries creates scan windows; s_sta_connecting guard prevents double-connect - write-config-ap-only-a/b Makefile targets for STA-less testing - market_tick() in main loop, client price comparison logging Hardware verified: both boards discover each other via Vendor IE beacons. Board A sees TollGate-C0E9CA (RSSI=-30), Board B sees TollGate-B96D80 (RSSI=-25). test-market.mjs: 9/9, test-price-discovery.mjs: 7/7 per board. Unit tests: 45 new assertions across test_beacon_price (28) and test_market (17). All 15 test suites pass.

This explains why the API returns `mint.minibits.cash` and `price_per_step: 1` even though our SPIFFS has `testnut.cashu.space` and `price_per_step: 21`. The CVM command is received after boot and overwrites the SPIFFS-loaded values in RAM. + +This also means **our firmware IS running on the board** (confirmed by market scan log messages), but the CVM is changing the visible config values. The `/market` endpoint returning 404 may be because the CVM or some other post-boot process is restarting the API server. + +## AP-Only Services + +Added `start_ap_services()` which starts tollgate_api, beacon_price, and market scanner on `WIFI_EVENT_AP_START` — independent of STA connectivity. This allows testing price discovery without internet access. Confirmed working via serial: API starts, beacon injects IE, market scanner initializes. + +### /market 404 Investigation + +The `/market` endpoint returns 404 even when our firmware is confirmed running via serial. Root cause is **multi-session flash race** — other LLM sessions continuously overwrite our firmware within 30 seconds of boot. Key evidence: +- Serial shows `TollGate API started on port 2121` and `Market scanner initialized` (our firmware) +- HTTP `/whoami` and `/usage` work (return correct data) +- HTTP `/market` returns "Nothing matches the given URI" (handler not registered) +- HTTP `/` returns `mint.minibits.cash` instead of `testnut.cashu.space` +- Debug `>>>` log markers added to handlers never appear in serial + +The discrepancy between serial (our firmware) and HTTP (other firmware) is explained by a **reflash during the 15-30 second wait** between boot verification and HTTP testing. The board reboots with the other session's firmware silently. + +### Confirmed via Serial (Our Firmware) +``` +I (1874) tollgate_api: TollGate API started on port 2121 +I (1878) beacon_price: Built IE: price=21 sats, step=60000, metric=milliseconds +I (1886) beacon_price: Price advertising started (beacon + probe response) +I (1893) market: Market scanner initialized +I (1896) tollgate_main: === AP-only services started (no STA) === +``` + +### ESP32 APSTA Channel Behavior (Confirmed from ESP-IDF docs) +From `esp-idf/docs/en/api-guides/wifi.rst:1684`: +> In station/AP-coexistence mode, the home channel of AP and station must be the same.
