+# 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.
+
+The RF filter components are set for use in the vicinity of 435 Mhz.
+
+For the latest TeleBT firmware and related software, please
+visit the [AltOS](../AltOS) page on this site.
+
+## Features ##
+
+### User View ###
+
+* 70cm ham-band transceiver compatible with [Altus Metrum](../) products,
+  programmed for 38k4 GFSK data rate with forward error correction
+* micro USB interface
+* 4 pin Tyco MicroMaTch connector for debug and flash programming
+* 8 pin Tyco MicroMaTch connector supports serial or SPI interface
+* 900mAh LiPo battery charged via USB 
+
+### Developer View ###

+
+## Artifacts ##
+
+There is a single manual for all Altus Metrum products,
+which is available in [html](../AltOS/doc/altusmetrum.html) and 
+[pdf](../AltOS/doc/altusmetrum.pdf) formats.
+
+The hardware design current gEDA files are available from 
+[git.gag.com](http://git.gag.com) in the project 
+[hw/teleshield](http://git.gag.com/?p=hw/telebt;a=summary).  
+
+## Future Plans ##
+
+Two prototype versions have been built with different physical form factors,
+v0.2 could be put into production at any time.
