3 TeleBT provides the equivalent of a [TeleDongle](../TeleDongle), with
4 the addition of [Bluetooth](http://www.bluetooth.com) as an alternative to
5 USB for connection to the ground station computer.
7 The RF filter components are set for use in the vicinity of 435 Mhz.
9 These are photos of prototype version 0.2:

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