UUID String() method not accessible?

[ssokol]

Using version 0.10.0, the following line:

fmt.Printf("Subscribing to notifications on characteristic %s...\n", targetChar.UUID.String())

causes the following error:

./fvFlightBar.go:76:87: targetChar.UUID.String undefined (type func() bluetooth.UUID has no field or method String)

Both the docs and the code seem to think there's a String() method but the compiler begs to differ.

For more context, here's more of the code:

	// 6. Discover the characteristic within that service
	chars, err := targetService.DiscoverCharacteristics([]bluetooth.UUID{charUUID})
	if err != nil {
		log.Fatalf("Failed to discover characteristics: %v", err)
	}
	if len(chars) == 0 {
		log.Fatalf("Characteristic %s not found", charUUID.String())
	}
	targetChar := chars[0]

	// 7. Subscribe to notifications on the found characteristic
	fmt.Printf("Subscribing to notifications on characteristic %s...\n", targetChar.UUID.String())
	err = targetChar.EnableNotifications(func(value []byte) {
		// Convert received bytes to a hexadecimal string
		hexData := hex.EncodeToString(value)
		fmt.Printf("Notification data (hex): %s\n", hexData)
	})
	if err != nil {
		log.Fatalf("Failed to subscribe to notifications: %v", err)
	}

What is the target OS you are trying to run on?

@ssokol You need to call .UUID on DeviceCharacteristic; it does not have a UUID field, it has a method (type func() bluetooth.UUID has no field or method String).
