You have to set the device name when you initialize your GAP parameters, and set the device name type when you initialize your advertising parameters. There are good examples of this in the SDK service example projects.</p> <p>To send your system id and RSSI in the advertising packet, you can use the manufacturers specific data portion of the advertising packet. There is good information in this forum on that if you search for it.</p><div style="clear:both;"></div>
