Bootloader Installation: EMB-BT1

Installing the KOS bootloader installs the node manager, the necessary software to recognize the board as a KOS device. KOS Studio recognizes KOS Devices and can interact with them as needed.

Node discovery lists all the possible devices running KOS in your network and all devices connected via KOS Studio within your organization.
