By default, no software is pre-downloaded on a GR5515 SK Board. It is recommended to download the Bluetooth
or peripheral application example projects provided in a GR551x SDK to a GR5515 SK Board for development and
debugging.
To make best use of the GR5515 SK, it is recommended to refer to the following documents.
