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 the first production version, 1.0:

62 There is a single manual for all Altus Metrum products,
63 which is available in [html](../AltOS/doc/altusmetrum.html) and
64 [pdf](../AltOS/doc/altusmetrum.pdf) formats.
66 The hardware design current gEDA files are available from
67 [git.gag.com](http://git.gag.com) in the project
68 [hw/teleshield](http://git.gag.com/?p=hw/telebt;a=summary).
70 For those who don't have ready access to the gEDA suite, here are pdf snapshots
71 of the files for Production PCB version 1.0 in more easily readable form.

79 Production version 1.0 is available to purchase! TeleBT works
80 with both AltosUI version 1.2 and later, and a new
81 [Android](http://www.android.com) application
82 called [AltosDroid](../AltosDroid).
84 We're pretty happy with TeleBT and have no plans to change it at this time.
