Hello everyone, I am Morgan, the principal engineer of Nuvoton Technology. Today, I will show you how to use 4G LTE or NB-IoT with Mbed OS on NuMaker-IoT-M487 development board. This tutorial needs a cellular expansion board to work with NuMaker-IoT-M487 development board. You can purchase the 4G LTE expansion board, RF-EC21A, on Nuvoton Direct (https://direct.nuvoton.com/communication-module/). Please install your 4G LTE SIM card in the mini SIM card slot on the back, and install the antenna at the MAIN connector on the front of the board. Although there is an NB-IoT expansion board, it requires an NB-IoT SIM card. Using LTE is more convenient. Just use your own LTE SIM card which has data plan. Then install the expansion board to the Arduino UNO connector of the NuMaker-IoT-M487 development board. Because the power consumption of the 4G LTE module is higher, it is not enough to supply power from USB only. You need to plug in the 5V/2A power supply. If you use NB-IoT module, no additional power supply is needed. We used “New” to select a template to create a new project. This time, we use the example on GitHub to create a new project. The URL of template used for this tutorial is https://github.com/OpenNuvoton/NuMaker-mbed-Cellular-example In chrome browser, enter the URL https://ide.mbed.com to use Mbed Online Compiler environment. After you log in, make sure that NuMaker-IoT-M487 board already selected in the upper right corner. If not, please refer Nuvoton IoT Tutorial series “Get Started with Mbed OS” which has a detailed description of how to add a board. Click the second option “Import” on the upper left. In the Import Wizard, click “Click here” On the “Source URL:”, enter the tempalte URL https://github.com/OpenNuvoton/NuMaker-mbed-Cellular-example . Then move mouse cursor to “Import Name:” and click it, the Project name will be automatically fill in. Then click “Import” button. Now you can see that the sample code has loaded. Depending on the cellular module used, the configuration may need to be modified. Click on “Readme.md” to open it. It lists configurations for supported cellular modules. Because the tutorial uses RF-EC21A expansion board which includes a Quectel EC21 LTE module, let’s check and modify the configuration in mbed_app.json file. Click the “mbed_app.json” file to open it. It is a JSON file to customize compile time configuration parameters in Mbed OS. The “*” (asterisk) in “target_overrides” session indicates all development boards are applicable. You can set in the designated board session, so the settings are only applicable to the specified board. The default mbed_app.json file in the example has configured for RF-EC21A. Such as, "target.network-default-interface-type" has set to "CELLULAR" for cellular connection. Both "lwip.ppp-enabled” and "lwip.tcp-enabled" set to true. Use generic AT3GPP driver for RF-EC21A ("GENERIC_AT3GPP.provide-default": true) And the RF-EC21A UART connects on Arduino D0/D1 ("GENERIC_AT3GPP.tx": "D1" and "GENERIC_AT3GPP.rx": "D0") When your SIM card installed in your mobile phone, you can find the APN, username and password settings in your mobile phone. Or contact your telecom operator to get this information. In the example, APN has set to “internet”, no username, and no password. (Move mouse cursor around these settings) The final setting to check is PIN code. In the example, the setting is no PIN code. If your SIM card has PIN code, for example 1234, please set it like this “\”1234\”” (Move mouse cursor around the setting) Save it then build it. It is in compiling, please wait a moment. Then you can see the last message is “Success!”. The browser will download the binary firmware file directly after a successful compiling. It will be saved in a default download folder or the folder based on your browser setting. In Chrome, you can click download file and select “Show in folder”. Then we connect the NuMaker-IoT-M487 USB port to your computer and don’t forget to plug in external 5V power supply. Please find the virtual COM port assigned for NuMaker-IoT-M487 in Device Manager. In the demonstration, the “Nu-Link Virtual Com Port” is COMx. Then use your favorite terminal tool. Here we use Putty. Open the COMx port with 115200 baud rate, 8 bits, 1 stop bit, none parity, and no flow control settings. Then “Open” it. Let’s back to the download folder where you can see the binary firmware file (NuMaker-mbed-Cellular-example.NUMAER_IOT_M487.bin). Drag and drop the file to NuMicro MCU drive. You will see the copying progress dialog box. You can see the connection messages printed on terminal. It shows that the board creates a TCP connection to server “echo.mbedcloudtesting.com”, send 4 bytes data and get the data back from server. That’s all for this tutorial. Thank you.

以新唐 NuMaker NUC980 IIoT 為平台，使用 Linux 進行開發，學習開發各式功能，觀看本片，您將學會在 NuMaker NUC980 IIoT上使用 Ethernet 連接到 AWS IoT 服務。 大家好我是新唐工程師 Miya，今天要為各位介紹，如何使用 NuMaker NUC980 IIoT 開發平台連接 Amazon 的物聯網，以下簡稱 AWS 連結網址 https://aws.amazon.com/ ，登入 AWS 帳號 點擊右上角的 “Sign In to the Console”，進入帳號登入頁面 輸入您的帳號密碼，點擊 “Sign In” 進行登入 登入之後，進到 “AWS 管理控制台” 頁面 在搜尋欄位，輸入 “IoT Core”，會出現 IoT Core 連結，點擊進入 在左邊的欄位選擇 “入門” 頁面 在 “設定裝置” 點擊 “開始使用” ，開始設置 IoT 裝置 選擇連接 AWS IoT連線方式。platform 請選擇 Linux， SDK 請選擇 Python。 點擊 “下一步” 進到下一個頁面。 接下來開始註冊一個 IoT Thing，有三個步驟。 首先命名 IoT Thing，接著按下一步。 這個連線套件不會用到，按取消之後跳到下一步。 接下來2個頁面直接按 “完成” “完成”。 系統會跳回到管理頁面。 點擊左側選單 “管理”  “實物”。可以看到剛剛建立的 my-IoT 出現在 IoT Thing 裡面了。 接下來要對這個新建立的 Thing 做一些設定，直接點擊新建立的 Thing-my-IoT，進入管理頁面。 在左側選單，選擇 “互動” 。 在互動頁面裡可以看到 Thing 的 HTTPS 連結。 複製此 HTTPS，用戶端應用程序需要知道這個連結，才能夠連接到這個 IoT Thing。 接下來下載安全憑證，請在頁面左側選單，點擊 “安全”，進入憑證頁面。 然後點擊 “建立憑證”。 憑證建立完成會產生三個檔案，分別是憑證、公鑰及私鑰。分別點擊 “下載”以下載這三個檔案，NuMaker NUC980 IIoT 開發平台用戶端進行 AWS IoT 連線的時候會用到。 下載完成之後，點擊 “啟用”，使這個安全憑證生效。 接著還需要下載 AWS IoT 的根憑證，點擊 “CA 下載” 連結，以開啟另一個瀏覽頁面。 點 CA Certificates for Service Authentication 連結，系統會跳到 AWS IoT root CA 的下載頁面。 請選擇第一個根憑證，RSA 2048 bit key，按滑鼠右鍵，另存連結，存到檔案 “AmazonRootCA1.pem”。 下載完成之後，回到剛剛的頁面。 接下來，點擊 “連接政策”，進行 policy 設定。 點擊 “建立新政策”以建立一個新的 policy。 先輸入 policy 名稱。 選擇 “進階模式”，直接編輯 policy 內容。 在Effect 敘述輸入 Allow，允許操作。 在 Action 敘述輸入 “I:*”，接受所有的 IoT 命令。 在 Resource 敘述輸入 “*”， 允許取用 resource。 按 “建立” 建立新的 Policy。 在左側選單，重新點擊 “管理”→ “實物”，選擇 my-IoT thing，回到 my-IoT 頁面。 再次點擊 “安全”，然後選擇剛才建立的憑證。 在憑證頁面左側的選單選擇 “政策”。目前 Policies 還是空的。 打開右上角的 “動作”下拉選單，選擇 “連接政策”。 在 Policy 列表裡面，會出現剛才新建立的 Policy。打勾選取，然後按 “連接 “，完成 policy 的附加。 這時候 Policies 頁面就會出現我們所選擇的 Policy 了。到這邊已經建立好了雲端的 IoT Thing。接下來，要在 NuMaker NUC980 IoT 板上建立用戶端 IoT 應用。 請連接網址 tls.mbed.org/download 以下載 mbedTLS library。 點擊連結 mbed TLS 2.16.3(Apache) 進行下載儲存。 接下來要將把下載的 mbedTLS library 複製到 NUC980 Linux 開發環境下；先解壓 mbedTLS library後，用 git 下載 AWS 的 SDK。 git clone https://github.com/aws/aws-iot-device-sdk-embedded-C 下載完成之後，先刪除他在 external lib 目錄下的 mbedTLS 目錄，這是個空目錄。 將先前下載解壓後的 mbedTLS 目錄移動到 external lib 目錄下就可以直接編譯 AWS SDK 的範例了。 進到 AWS SDK 的 samples 目錄下的 Linux 目錄下可以看到 5 個 範例。要使用的範例是最底下這個 subscribe_publish_sample。 進到這個範例的目錄下。 有三個檔案，需要作一些修改。 首先修改 makefile，將 compiler linker 由 gcc，改為 NUC980 Linux toolchain 的 compiler linker。 51. 往底下找到 CRYPTO_LIB_DIR，修改路徑，將 crypto 刪除，這樣 makefile 就完成修改了。 (~00:25) 52. 接著是 header file，修改MQTT HOST 連結路徑，先前我們在 IoT thing 的 “互動” 頁面所複製 的 HTTPS 連結，將它貼到這裡。(~00:46) 53. CLIENT ID 請任意取一個名稱，不要與其他用戶端名稱重複即可。(~00:55) 54. MY THING NAME 要用前面建立的 IoT Thing 的名稱: my-IoT。(~01:02) 55. 底下的 ROOT CA file name，IoT Certificate file name，以及 IoT private key filename。 56. 前面在建立 IoT Thing 安全憑證過程中，有下載了 Root CA 及 IoT 安全憑證幾個檔案，請將 檔案名稱填寫到這裡。 最後是修改 點 C，系統會將範例程式執行檔放到 root file system 的 usr/bin 目錄下，並將憑證檔案放到 usr/certs 目錄下。 這裡請將憑證指定目錄改為 相對路徑的 ../certs。 接著打 make 直接進行編譯。 編譯需要幾分鐘的時間，影片跳過了編譯部分。 接下來，將編譯好的應用程序複製到 rootfs 的 /usr/bin 目錄下。 然後將根憑證及 IoT 安全憑證檔案複製到 rootfs 的 /usr/certs 目錄下。這裡已經事先複製好了。完成後到 BSP Linux 目錄下，編譯 kernel。 將 kernel 上傳到 IoT 開發板上面執行。 下 ifconfig + udhcpc 指令連接網絡。 由於憑證有時效性問題，需要修改系統時間，以免因為憑證過期導致無法連接。 進到 usr/bin 目錄下，執行 AWS用戶端範例程序。 可以看到用戶端已經成功連接 AWS 雲端。這個範例會不斷地發佈並且接收訊息。 - 更多產品資訊，請至新唐科技網站 https://bit.ly/3hVdcmC 購買管道：https://direct.nuvoton.com/tw/numaker-nuc980-iiot 聯絡我們： SalesSupport@nuvoton.com
