5. 操作手順

The AITIAO CC2531 Sniffer USB Dongle can be configured for different operational modes based on the firmware loaded onto it. Common uses include Zigbee protocol sniffing and acting as a Bluetooth adapter.

5.1. Zigbee Protocol Sniffer Mode

1. Load Sniffer Firmware: Ensure the appropriate Zigbee sniffer firmware is loaded onto the CC2531 dongle. This typically requires a programming tool and specific software.
2. Launch Sniffer Software: Open your preferred Zigbee protocol analysis software (e.g., Wireshark with Zigbee dissectors, SmartRF Packet Sniffer).
3. デバイスの選択： Within the software, select the CC2531 dongle as the capture interface.
4. Configure Channel: Set the desired Zigbee channel for sniffing. The device operates in the 2.405-2.485GHz range.
5. キャプチャを開始: Initiate packet capture to monitor Zigbee traffic. The software will display captured packets, allowing for detailed analysis of network communication.

5.2. Bluetooth Adapter Mode (BTool)

1. Load BTool Firmware: If using the dongle as a Bluetooth adapter, ensure the BTool compatible firmware is loaded.
2. Launch BTool Software: Open the BTool application or other compatible Bluetooth Low Energy (BLE) development tools.
3. デバイスに接続します: Establish a connection between the software and the CC2531 dongle.
4. Perform BLE Operations: Use the software to perform various BLE operations such as scanning for devices, connecting to peripherals, sending/receiving data, and debugging BLE applications.

6. メンテナンス

• クリーニング： Use a soft, dry cloth to clean the exterior of the dongle. Avoid using liquid cleaners or solvents.
• ストレージ： デバイスは直射日光や極端な温度を避け、涼しく乾燥した場所に保管してください。
• 取り扱い： Handle the dongle and antenna carefully to prevent physical damage to the connectors or circuit board.
• アンテナ接続： Periodically check that the external antenna is securely attached.

7。 トラブルシューティング

• デバイスが認識されません:
  • ドングルが USB ポートに完全に挿入されていることを確認します。
  • コンピュータの別のUSBポートを試してください。
  • Check Device Manager (Windows) or System Information (macOS/Linux) to see if the device is listed, even with an error. Reinstall drivers if necessary.
  • コンピュータを再起動します。
• No Data Capture (Sniffer Mode):
  • Verify that the correct sniffer firmware is loaded onto the dongle.
  • Confirm that the sniffer software is configured to use the CC2531 device.
  • Ensure the correct Zigbee channel is selected in the software, matching the network you intend to monitor.
  • Check the proximity to the Zigbee network; signal strength can affect capture.
• Bluetooth Connection Issues (BTool Mode):
  • Confirm BTool compatible firmware is loaded.
  • Ensure the target Bluetooth device is discoverable and within range.
  • 他の 2.4GHz デバイスからの干渉がないか確認してください。
