CHIP Ameba OTA Requestor Example

A prototype application that demonstrates OTA Requestor capabilities.

Building the Example Application

Pull docker image:

  $ docker pull connectedhomeip/chip-build-ameba:latest

Run docker container:

  $ docker run -it -v ${CHIP_DIR}:/root/chip connectedhomeip/chip-build-ameba:latest

Setup build environment:
```
  $ source ./scripts/bootstrap.sh
```
To build the demo application:
```
  $ ./scripts/build/build_examples.py --target ameba-amebad-ota-requestor build
```
The output image files are stored in out/ameba-amebad-ota-requestor/asdk/image folder.
The bootloader image files are stored in out/ameba-amebad-ota-requestor/asdk/bootloader folder.
After building the application, Ameba Image Tool is used to flash it to Ameba board.

Connect your device via USB and open Ameba Image Tool.
Select correct serial port and set baudrate as 115200.
Browse and add the corresponding image files in the Flash Download list to the correct locations
Click Download button.

Testing the Example Application

Launch the linux ota-provider-app and provide the SW_IMAGE_FILE

$ ./chip-ota-provider-app -f ${SW_IMAGE_FILE}

Commission the ota-provider-app using chip-tool

$ ./chip-tool pairing onnetwork 1 20202021

Input ATS$ command to start the CHIP ota-requestor task, then use chip-tool to commission it

$ ./chip-tool pairing ble-wifi 2 <SSID> <PASSWORD> 20202021 3840

After commissioning the ota-requestor, use the chip-tool to announce the ota-provider-app to start the OTA process

$ ./chip-tool otasoftwareupdaterequestor announce-ota-provider 1 0 0 0 2 0

The OTA process should include downloading the image, verification of image header, erasing upgraded flash partition, writing to flash and checksum verification
