  6. 打開這個磁碟，裡面有個檔案 firmware.bin

  7. 用新的 DAP firmware 取代

  8. 將USB重新插拔，新的firmware就生效了。

參考: 如何更換DAP Firmware?

2. 安裝Driver

  1. 將 Micro USB 接上 Ameba 的 DAP+DC+serial port 那一孔，另一端接上電腦，在電腦上關閉檔案視窗

3. 安裝 Arduino IDE 及相關資源

  1. 下載安裝 Arduino IDE
  2. 打開 Arduino IDE，為了讓 Arduino IDE 找到 Ameba 的設定檔，先到 File -> Preferences

  6. 初始化 wifi 成功

  7. clientID 及 uuid，請記下 uuid
    clientID 為 mac address 後 8 碼
    uuid 為 LASS + toTrytes(clientID)

  8. 讀 sensor 資料，編碼，發出聲明

查看感測紀錄

IOTA Tangle explorer

  1. uuid ： LASSPBUAUAXABBMBOBAB
    Tag (uuid + 'C') ：LASSPBUAUAXABBMBOBABC
    https://thetangle.org/tag/LASSPBUAUAXABBMBOBABC

  2. 在 Tangle explorer 用 Tag 搜尋

  3. 結果

  4. Message 選 Text 可看見相關資料
