The app now speaks the station-link protocol of the new obu-firmware. Esp32Link picks the transport from Settings (UsbSerialTransport or the new BleLinkTransport), tells the previous firmware from the new one by its heartbeat, and runs the session: STATION_CONFIGURE with the current pseudonym MAC (which also starts the board's radio), CREDENTIALS_PROVISION of the bundled demo chain when the board has no ticket, then per message a POTI_UPDATE and a BTP_DATA_REQUEST. Received messages still arrive as V2X_RX frames, so the receive side is unchanged. A board on the previous firmware keeps working for CAM over USB. Settings > Connection > ESP32-C5: link USB-C or Bluetooth, transmit CAM or VAM, "Sign outgoing messages" (on by default). The connection card, top bar and dashboard show the link in use, the pairing passkey and signing counters. - VAM: VamUperCodec (TS 103 300-3 V2.3.1, bytes checked against asn1tools) and VamGenerationRules (clause 6.4, Tables 16/17). - BLE: the firmware's GATT layout (service 0000C175-...), MTU 517, pairing and encryption settled before any other operation (short timeouts during pairing made it loop), backoff between attempts, reasons on the card. - Clock: a PoTi goes to the board once per new fix and never moves the board's clock backwards except for a real correction (>= 60 s); stale and wobbling fix times made the board answer time_regression and restart its stack every few seconds. GnssTimeSource keeps the last measured phone-clock error while GNSS time drops out indoors: the bench phone is 14 minutes fast, and falling back to it made every transmitted timestamp jump by that much. - assets/demo-chain.vcr: throwaway, not EU-registered demo chain generated 2026-09-23 (AT B80B49387A4C12EB, psid 36 and 638). Its private key ships with the app on purpose; receivers verifying against the EU trust list drop what it signs. - Bluetooth permissions requested at start-up on Android 12+. StationLinkTest pins the codec to bytes from the colleague's Python implementation (microbu_link/messages.py). 103 unit tests pass.
