# TeleBT
TeleBT provides the equivalent of a [TeleDongle](../TeleDongle), with
-the addition of [Bluetooth](http://www.bluetooth.com) as an alternative to
-USB for connection to the ground station computer.
+both USB and [Bluetooth](http://www.bluetooth.com) for connection to the
+ground station computer or mobile device.
The RF filter components are set for use in the vicinity of 435 Mhz.

+These are photos of the first production version, 1.0. Maybe someday we'll
+get around to adding photos of the current production version 4.0, but they
+look pretty similar once they're in the blue box!

-## Future Plans ##
+## [History of TeleBT](history) ##
-The inventory of version 1.0 boards was lost in the fire that destroyed
-Bdale's home in June of 2013. Version 1.1 will be available for purchase
-we hope by the end of October 2013.
-
-TeleBT works with both AltosUI version 1.2 and later, and a new
-[Android](http://www.android.com) application
-called [AltosDroid](../AltosDroid).
