4 TeleBT provides the equivalent of a [TeleDongle](../TeleDongle), with
5 the addition of [Bluetooth](http://www.bluetooth.com) as an alternative to
6 USB for connection to the ground station computer.
8 The RF filter components are set for use in the vicinity of 435 Mhz.
10 These are photos of the first production version, 1.0:

15 And here's what it looks like packaged with battery, attached to an Arrow
16 3-element yagi, ready for use:

21 For the latest TeleBT firmware and related software, please
22 visit the [AltOS](../AltOS) and [AltosDroid](../AltosDroid) pages on this
23 site. There is also a compatible iOS application available for sale from our
24 friends at [Iron Sheep Productions](http://altosui.ironsheep.biz/).
26 If you're using TeleBT with an [Arrow](http://www.arrowantennas.com/) yagi,
27 we now have a 3D-printable [mount](mount/) design available!
33 * 70cm ham-band transceiver compatible with [Altus Metrum](../) products,
34 programmed for 38k4 GFSK data rate with forward error correction
36 * 4 pin Tyco MicroMaTch connector for debug and flash programming
37 * 8 pin Tyco MicroMaTch connector supports serial or SPI interface
38 * 850mAh LiPo battery charged via USB

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

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