I am trying to commission an ESP32-H2 Matter device using the chip-tool. It's running the Light Switch sample. I can commissioning it using the iOS Home App, so I know the code on it's working okay.
I would like to understand more about the Fabric process, so I'd like to use the Home Pod powered Thread network rather than setting up an instance of Open Thread Border Router.
I have created a simple iOS app and can fetch the activeOperationalDataSet from the Preferred network using
func obtainPreferredNetworkCredentials() async -> (Void) {
let client = THClient()
let bIsPreferredAvailable = await client.isPreferredAvailable()
if bIsPreferredAvailable == true
{
var credential: THCredentials?
do {
credential = try await client.preferredCredentials()
if let dataset = credential?.activeOperationalDataSet {
print(dataset.hexDescription)
}
} catch {
print("Failed to get the credentials")
}
}
}
The hexDescription comes from this extension
extension Data {
var hexDescription: String {
return reduce("") {$0 + String(format: "%02x", $1)}
}
}
I am decoding the Data and displaying it as a hex string. It looks something like this:
0e080000000000000000000300001935060004001fffc002089f651677026f48070708fd9f65167702000ee90914b5d1097de9bb0818dc94690c0402a0f7f8
However, when I attempt to commission the device, it fails during ThreadSetup. Googling the issue says most likely the Operational Dataset is wrong in some way.
Before I spend too much time on this, I want to make sure I'm doing the right thing in terms of getting the Operational Dataset to use with the chip-tool.
Any help is appreciated!
