| How do the energy savings when you connect a mounting divide to a Bluetooth Low Energy sensor? |
Thank you for your comment. As you pointed out, reducing energy consumption of mounting device is an important issue. Currently, as an initial study, we are not considering reducing energy consumption, but this is a future issue. One possible way is to use a microcomputer with low power consumption, because Raspberry Pi used in this paper consumes much energy.

| In the future, it is said that communication systems such as Wi-Fi will be available underwater, but what kind of services has the advantage of being able to use Wi-Fi underwater? |
Thank you for your comments. There are some examples of usages. For example, if the smartwatches or smartphones worn by divers could connect to the Internet while underwater, the divers could use various services while underwater. In addition, if the data acquired by the underwater camera could be seen in real time above the water, it is useful for aquaculture, fishing, marine activity, and so on. Alternatively, using underwater wireless sensors to assess in real time the water temperature and how the shape of the cage was changing would help to make aquaculture more efficient. |

| Thank you for your presentation. Can you tell me how much effect the system will have on the noise in the experiment? |
Thank you for your question.
Yes, noise affects performance of data communication. The experiments were conducted in laboratory. In the experiment, audible sound was used and there was noise coming out of the air conditioning.
We are considering using the proposed system in the sea, and we think that it is necessary to investigate the noise generated in the sea and to consider the communication method considering the influence of the noise in the future.

| Thank you for your presentation. Is it possible to use a combination of wired and Bluetooth to expand efficiency through transit? |
Thank you for your question.
In the presentation, I introduced underwater communication cables. The cable is supposed to be used for WiFi communication, but it can also be used for Bluetooth communication.

| Hello Dear,
Thank you for the presentation, I want what are the novelty of your article compared to what existed. |
Thank you for the question.
Currently, there is limited way to use commercially available wireless devices underwater.
One way is using cable, however, it has drawback.
Our system focuses on using a commercially available BLE sensor underwater without using cable. |
