This example uses the Developer Kit (with AliOS Things ported) as the development hardware to implement data uploading from a board-mounted temperature sensor to Link Develop and uses Web App for demonstration.
Configuring the Environment
You need to configure the environment before you use BoneEngine to perform device-side development. The configuration steps are shown as follows:
- Install Node.js (version 6.4.0 or later; for front-end development, version 8.9.0 or later is recommended).
- Install the be-cli tool to provide support for updating app.bin via serial port or over the network:
npm i be-cli -g -P. If you are still prompted that the command cannot be found even when you run
beafter the preceding global installation is done, run the
npm prefix -gcommand to get the module installation path of Node.js, and then, simply add the global installation path in the output to the "Path" entry of the environment variable.
- (For Windows users only) Install Python, Visual Studio, and the AliOS plug-in. Then, install this Hardware USB driver.
- Install Git and download AliOS Things source code:
git clone email@example.com:alibaba/AliOS-Things.git.
Now that the environment is configured, we are ready to begin development.
Developing on the Cloud
We will be using Link Develop to set up our IoT network on Alibaba Cloud. Choose Create Project (you may name it as you want) > Device Development > Add Product. Select Other for the product type, select Wi-Fi for the communication method, and select Alink for the data format.
Select Add Custom Features in Product Details and add the following features:
Choose Device Development > Add Debugging Devices, and take note of the device triplets.
Developing on the Device
Open the source code directory of AliOS Things in a compiler, and then, open the
AliOS-Things/framework/tinyengine/samples/app/lcd_shtc1_mqtt/device.js file, and change Three Device Elements to Device Triplets that you obtained before. Save your changes.
Use the terminal to compile the sample application:
be -p samples/app/lcd_shtc1_mqtt.
Connect Developer Kit to a computer and run
Burn the compiled bin file to the device:
be push app.bin
Restart the device. After restarting, the device automatically loads, runs this file, and simultaneously uploads it to the Link Develop platform.
Developing in Web App
To help you get started quickly, here we use the visual creation feature of Web App integrated into the new version of Link Develop. All we need to do is drag the components of the hygrothermograph and connect to your data.
The mix of AliOS Things TinyEngine and Link Develop Bone.js allows front-end developers to quickly and seamlessly get started with IoT development, without having to learn other programming languages.
