I used https://aistudio.google.com/live to test function calling with gemini-2.5-flash-preview-native-audio-dialog , add [ { "name": "set_light_values", "description": "Sets the brightness and color temperature of a light.", "parameters": { "type": "object", "properties": { "brightness": { "type": …
