CHIP Ameba Air Purifier Example

This example demonstrates the Matter air purifier application on Ameba platform.

Supported Device

The CHIP demo application is supported on Ameba RTL8722DM Board.

Building the Example Application

  • Check out the Ameba repository in the same folder/directory as the Matter SDK repository:
git clone https://github.com/ambiot/ambd_matter.git
  • Setup build environment:
$ cd connectedhomeip
$ source scripts/bootstrap.sh
  • To build the demo application:
$ cd ambd_matter/project/realtek_amebaD_va0_example/GCC-RELEASE/project_lp/
$ make all

$ cd ambd_matter/project/realtek_amebaD_va0_example/GCC-RELEASE/project_hp/
$ make -C asdk air_purifier

From the same directory:
$ make all
  • Combine the three output images for flashing using the Ameba Image Tool:
$ cd ambd_matter/tools/AmebaD/Image_Tool_Linux

$ sudo ./AmebaD_ImageTool -combine \
  ../../../project/realtek_amebaD_va0_example/GCC-RELEASE/project_lp/asdk/image/km0_boot_all.bin 0x0000 \
  ../../../project/realtek_amebaD_va0_example/GCC-RELEASE/project_hp/asdk/image/km4_boot_all.bin 0x4000 \
  ../../../project/realtek_amebaD_va0_example/GCC-RELEASE/project_hp/asdk/image/km0_km4_image2.bin 0x6000
  • This will produce a combined Image_All.bin file alongside the image tool that can be flashed using the Ameba Image Tool:
  1. Connect your device via USB
  2. Edit the ambd_matter/tools/AmebaD/mpp.ini file with the correct port setting (the rest of the settings should be correct)
  3. Click Download button and the Reset button to get the board into serial download mode
  4. Flash on the image:
$ cd ambd_matter/tools/AmebaD/Image_Tool_Linux
$ ./AmebaD_ImageTool -download

Commissioning

There are two commissioning modes supported by Ameba platform:

BLE mode

  1. Build and Flash
  2. The example will run automatically after booting the Ameba board.
  3. Test with Chip-Tool

IP mode

  1. Build and Flash
  2. The example will run automatically after booting the Ameba board.
  3. Connect to AP using ATW0, ATW1, ATWC commands
  4. Test with Chip-Tool

Cluster Control

After successful commissioning, the air purifier clusters can be read and controlled using Chip-Tool.

The Air Purifier is a composed device. The example has endpoints configured as follows:

  • Air purifier on endpoint 1
  • Air quality sensor on endpoint 2
  • Temperature sensor on endpoint 3
  • Relative humidity sensor on endpoint 4

Example commands using the chip tool:

$ ./chip-tool fancontrol write speed-setting 10 ${NODE_ID_TO_ASSIGN} 1
$ ./chip-tool formaldehydeconcentrationmeasurement read level-value ${NODE_ID_TO_ASSIGN} 2
$ ./chip-tool temperaturemeasurement read measured-value ${NODE_ID_TO_ASSIGN} 3
$ ./chip-tool relativehumiditymeasurement read measured-value ${NODE_ID_TO_ASSIGN} 4
