Make android app act as an OTA provider

[MrLiuYunPing]

Feature description

...
I have done this in iOS, because the Matter.framework has supported to set an OTA delegate, and has some test cases related. But, in android, I announce the controller nodeId to the device to update, when I set OTA delegate using endpoint 0, it always failed(emberAfFindClusterServerEndpointIndex method returns Invalid). When i look the logs on the device, it shows: Received Command Response Status for Endpoint=0 Cluster=0x0000_0029 Command=0x0000_0000 Status=0x7f . . .Status=0x7f whichs means unsupported endpoint. I don't know why iOS success but android failed?

Platform

android

Platform Version(s)

iOS implements emberAfFindClusterServerEndpointIndex specifically so OTA can work. See

connectedhomeip/src/darwin/Framework/CHIP/MTRIMDispatch.mm

Lines 230 to 240 in 19ae369

	* Called by the OTA provider cluster server to determine an index
	* into its array.
	*/
	uint16_t emberAfFindClusterServerEndpointIndex(EndpointId endpoint, ClusterId clusterId)
	{
	if (endpoint == kSupportedEndpoint && clusterId == OtaSoftwareUpdateProvider::Id) {
	return 0;
	}
	return UINT16_MAX;
	}

Android might need to do something similar.

@bzbarsky-apple Hi Could you give me a simple example how to make OTA process on iOS side? I didn't find any docs on this, I want to do OTA function on iOS, Thank you .

[yusheng-jia]

@MrLiuYunPing Hi could you tell me how you implemented on iOS? Thank you

[bzbarsky-apple]

@yusheng-jia On iOS, set otaProviderDelegate in the MTRDeviceControllerFactoryParams to a non-nil value before starting up the controller factory. Then you will get calls to your delegate implementation as needed.

@MrLiuYunPing @swap9391 @yusheng-jia @srdantas may I know your requirement on android for ota-provider? for example, you wanna use android-chip-tool or your android app to announce there is ota software, then send this image to your wifi-device using bdx over wifi? I think currently there is no java/jni api for setDelegate for ota-provider, how do you do that, wanna get more details so that we can plan the feature. thanks

Thank you for support, you're totally right . I did this on iOS, iOS has MTROTAProviderDelegate protocol, it has very detailed method to implement the whole OTA process on App side.

@yusheng-jia are you in matter slack channel, if yes, what is your slack name?

[yusheng-jia]

I'm in slack channel, and my name is Jayson Jia, Thank you!

@yunhanw-google Hi, I am also surveying this feature. Is an OTA provider currently being developed?

[yunhanw-google]

@eling22 are you in slack, could you find me with yunhanw in slack? Wanna understand your requirement, thanks

[yunhanw-google]

@eling22 and @MrLiuYunPing we are actively supporting this feature, we would create several PR for this work soon.

I don't have knowledge of an android app, but I was facing same issue with linux PC. In your android app if you want to be as an OTA provider then OTA provider cluster must be in server mode. I have resolved this error by doing following changes.
(1) updated matter version 1.2 from 1.1 because updated ZAP version can support OTA Provider cluster as a Server
(2) Enabled OTA provider cluster as a server.
By doing these, you will be able to resolve this.

@Shahmeera @eling22 @MrLiuYunPing @yusheng-jia @swap9391 @srdantas we have officially added the OTA support in android side, please check-in, thanks
