[Smartphone] --> [Cloud Server] --> [Raspberry Pi with DS150E] --> [Car OBD] The Pi runs a Python Flask server that maps HTTP endpoints to diagnostic commands: time ser = serial.Serial('COM3'

// 2. Get functions PT_OPEN pOpen = (PT_OPEN)GetProcAddress(hDll, "PassThruOpen"); PT_CONNECT pConnect = (PT_CONNECT)GetProcAddress(hDll, "PassThruConnect");

: In practice, you must handle message packing (CAN frames are 8 bytes max). The DS150E expects little-endian byte ordering on USB. 4. Python Automation with PySerial and Custom Protocol Because the DS150E over VCP exposes raw serial (115200 baud, 8N1), you can craft low-level diagnostic requests. Example: Read Engine RPM via KWP2000 (ISO 14230) import serial, time ser = serial.Serial('COM3', 115200, timeout=1) KWP2000 fast init (5 baud init sequence not needed for DS150E) def kwp_request(service, data=b''): # Build header: 0x68 (target), 0x6A (source), 0x81 (length) length = 2 + len(data) # service byte + data frame = bytes([0x68, 0x6A, length, service]) + data ser.write(frame) time.sleep(0.05) return ser.read(256) Request engine RPM (PID 0x0C) response = kwp_request(0x01, b'\x0C') if len(response) > 4: rpm_raw = response[4] * 256 + response[5] print(f"RPM: rpm_raw/4:.0f")
