Sending commands to google assistant using script

Question

I have configured Google Assistant SDK in Raspberry Pi 3 and demo application is working fine. Is there any way to send “OK Google, Example Command” to Google Assistant SDK using Python script? Or it will only take input from Mic?

I am planning to write tiny mobile application which will send commands to my Raspberry Pi google assistant application.

UPDATE: even if it is an old question, here is the latest update.

It is now possible using the v1alpha2 version. The gRPC message AssistConfig is defined as an union where you can choose between an audio out config or a text query.

If you are using the python library, see the AssistConfig. Here is an example of config using a text query (adapted from the pushtotalk.py sample, line 183):

config = embedded_assistant_pb2.AssistConfig(
        # instead of audio_in_config
        # note: no need to use 'OK google'
        text_query = "who are you ?", 
        audio_out_config=embedded_assistant_pb2.AudioOutConfig(
            encoding='LINEAR16',
            sample_rate_hertz=self.conversation_stream.sample_rate,
            volume_percentage=self.conversation_stream.volume_percentage,
        ),
        dialog_state_in=dialog_state_in,
        device_config=embedded_assistant_pb2.DeviceConfig(
            device_id=self.device_id,
            device_model_id=self.device_model_id,
        )
    )

The current release of the Assistant SDK (Alpha v1) only supports sending and receiving audio. This is a frequent request, however, and we'll see what they provide in future updates.
