A BlueTooth Daughter Board for TNC-X!
X-BT2 is a plug in daughter board for TNC-X that allows you to connect your BlueTooth-enabled phone or PC to TNC-X wirelessly. The BlueTooth TNC-X will show up on your phone or computer as a standard serial port. You can carry your phone around the house with you and monitor APRS activity! X-BT plugs into the expansion header contained on every TNC-X.
A note on range: A lot of people ask whether the fact that TNC-X is in a metal enclosure effects the X-BT2's range. Of course there is some shielding from the TNC-X box. I find that when the top of the box is on the X-BT2's range still covers anywhere in my office and the associated hallway. It this is insufficent, you can remove the TNC-X top. When I do this range improves to almost all of my house.
