I have the same exact problem. I'm trying to run the interaction in the background using the Apple sample code changing this function.
func setupAccessory(_ configData: Data, name: String,peerIdentifier:UUID) {
updateInfoLabel(with: "Received configuration data from '\(name)'. Running session.")
do {
//configuration = try NINearbyAccessoryConfiguration(data: configData)
if #available(iOS 16.0, *) {
print("ios 16 background configuration active")
configuration = try NINearbyAccessoryConfiguration(accessoryData: configData, bluetoothPeerIdentifier: peerIdentifier)
} else {
// Fallback on earlier versions
print("ios <16 background configuration not active")
configuration = try NINearbyAccessoryConfiguration(data: configData)
}
} catch {
// Stop and display the issue because the incoming data is invalid.
// In your app, debug the accessory data to ensure an expected
// format.
updateInfoLabel(with: "Failed to create NINearbyAccessoryConfiguration for '\(name)'. Error: \(error)")
return
}
// Cache the token to correlate updates with this accessory.
cacheToken(configuration!.accessoryDiscoveryToken, accessoryName: name)
niSession.run(configuration!)
}
