The OBDPeak K2 is a compact Bluetooth OBD-II scanner used for vehicle diagnostics, data logging, and live telemetry via mobile apps. Recent firmware updates for OBD-II adapters like the K2 focus on improving Bluetooth stability, expanding protocol support (CAN FD, extended CAN IDs), fixing misread trouble codes, and tightening sleep/wake power management to reduce battery drain. Security hardening is another common theme: authenticated firmware signing to prevent unauthorized modification, encrypted Bluetooth pairing, and mitigation of known vulnerabilities in AT command processing. Performance improvements often include higher data sampling rates, more efficient PID multiplexing, and better handling of simultaneous requests from multiple apps. If the paper explores firmware update mechanisms, expect comparisons between bootloader designs (UART/DFU over BLE vs. USB), delta vs. full-image updates, fail-safe strategies (A/B partitions, rollback), and secure update delivery (signed packages, TLS servers). Empirical evaluation likely covers update time, success rate under intermittent connections, and impact on device availability.
