# 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.
These are photos of prototype version 0.2:

## 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 ###
* [TI CC1111F32](http://focus.ti.com/docs/prod/folders/print/cc1111f32.html) Low Power RF System-on-Chip
* Sub-1Ghz transceiver
* 8051 MCU
* 32k Flash
* 4k RAM
* USB 2.0
* 6 12-bit analog inputs (11 bits with single-ended sensors)
* 2 channels of serial I/O
* digital I/O
* interfaced to Arduino via async serial plus two handshake pins
* Raycom Bluetooth module interfaced to the CC1111 via async serial
* 150mA 3.3V LDO regulator
* input and output appear on 8-pin companion connector
* Software Features
* Written mostly in C with some 8051 assembler
* Runs from on-chip flash, uses on-chip RAM
* USB serial emulation for data interface
* Tools Used
* [gEDA](http://www.gpleda.org/) for schematic capture and PCB layout
* [SDCC](http://sdcc.sourceforge.net/) compiler and source debugger
* Licenses
* The hardware is licensed under the [TAPR](http://www.tapr.org) [Open Hardware License](http://www.tapr.org/ohl.html)
* The software is licensed [GPL version 2](http://www.gnu.org/licenses/old-licenses/gpl-2.0.html)
## 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.
