Hello,
Bluetooth data can be sent using Data to Server feature which can use MQTT acting as publisher to send sensor data to chosen broker. Data can be sent directly to AWS using device iot-endpoint in AWS as a hostname in Data to server configuration with appropriate authentication set up.
Router API is not yet available, but it is being worked on and is planed to be released this year, sadly there is not much information I am able to provide at the moment, since between now and release some things might still change.
Regards,
Vidas.
