TeleBT provides the equivalent of a TeleDongle, with both USB and Bluetooth for connection to the ground station computer or mobile device.
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 and AltosDroid pages on this
site. There is also a compatible iOS application available for sale from our
friends at Iron Sheep Productions.
If you're using TeleBT with an Arrow yagi,
we now have a 3D-printable mount design available!
