Laser Robot Vacuum SDK Quickstart

This topic describes how to develop with the SDK for a laser-guided robot vacuum with the Ubuntu system.

Preparation

• Install Ubuntu and GCC compiler. The examples in this topic use Ubuntu 18.04 and GCC 7.5.0.

  

• Get the SDK.

Procedure

1. Edit the demo in the SDK. Open the tuya_iot_soc_dev_entry.c and update values of PRODUCT_KEY, UUID, and AUTHKEY with those you obtained from the Tuya IoT Development Platform.

   

2. Check the name of the network interface on Ubuntu using a command.

   

3. Open the tuya_iot_wifi_net.c and change the value of WLAN_DEV to the name of the Ubuntu network interface.

   

4. Run the following command to build the code.

   sh build_app.sh demos/demo_soc_dev_wifi demo 1.0.0

   The following table lists the description of each parameter.

   Parameter name	Desription
   build_app.sh	The build script.
   demos/demo_soc_dev_wifi	The relative path to the application code.
   demo	The name of the generated executable file.
   1.0.0	The firmware version number.

   After the build is finished, the following information will be output.

   

5. Run the build.

   ./output/demo_1.0.0/demo

   

   If the program is run well and enters the access point (AP) mode, the output will look like this:

   
   By default, the SDK for Ubuntu only supports pairing through the AP mode.

6. Now, you are good to pair your device by using the mobile app. The following figure shows the pairing process.

   
   The app will be updated from time to time with new features and improvements, so the interface on the latest app prevails.

Test functions

Tap the Smart button on the app. The output on the Linux terminal will display the data point (DP) command from the cloud.
