Power FLARM question

We are developing a simple and low cost device (we named it
SoarTronic to add Bluetooth communication of FLARM traffic
information into European version of FLARM units. It also allows
task declaration and log file download. It is connected into RJ45
connector, and it draws operating voltage (40mA) from 3.3 V that
FLARM provides for external displays.

This is a nonprofit project we started to get FLARM traffic
information available in our club gliders. Since club members have
many types of flight computers, Bluetooth was chosen as
communication method. Price for this device is 30 EUR + delivery
from Finland.

If you think that this unit is useful with Power FLARM please let me
know. We hope to get 30 orders to cover the cost. Enclosed couple
links showing how to connect and use SoarTronic. These videos
show XCSoar runnig in Android phone, but it should work with any
device with BT, and with any flight computer SW.

Sean,
We already have some orders. Couple clubs will install this in
their entire fleet with FLARMs.
Please e-mail me your plane call-sign, and select your 4 digit BT
password, and your details. We will name your SoarTronic unit
according to your call-sign, so that it is easy to pair with your
computer device. I will inform you about the payment and
delivery. Tomorrow we will test the prototype for VHF radio
disturbances, and if the result is acceptable we will order factory
made PCBs and other components.

Just curious, are you using a module like this:
http://www.brunwinkel.de/elektronik/ics/btm400_6b/

I just build a device at my own design that meets your description. As I am
working nonprofit too, there is no competition. If interested, we can share
information. I have a dealer in Hong Kong who sells the modules for ~8,- ?
with free shipping. With a MAX3232 for the RS232, printed circuit board and
casing, I think your price is realistic.

Nice featu as the module is programmable, I set it up with the
registration of the glider as Bluetooth name.

Regards
Chris

Will either one work with a VW1150 Canbus and transmit info two ways
between a Streak and Canbus that contains Powerflarm and smart vario
data?

Thanks,

Mike

I cannot speak for the device offered by Kimmo, but it seems it works
similar as my design. As Kimmo mentioned, it should work with any device
that supports Bluetooth and can communicate with Flarm via the RJ45. The
Bluetooth is just a wireless extension of the serial data channel via RJ45.

Chris,

You are right, in this device all components are well known, and
you can build a similar system out from Bluetooth module and
RS232/TTL level sifter. I actually did so, but the result did not
look like something that I would trust. Also other club members
told me that "nice, but who will maintain those if you are not
here?". So I decided to look for more professional solution. What
was on the market was quite expensive compared to technology
needed.

There is one technical improvement in this device compared
what has been on the market. If you have an external display
connected into your FLARM unit and you want to connect
SoarTronic type device into the same RS232 line with it, you
normally either disconnect the external display's TX line, or add
a switch to select if you what to declare tasks over Bluetooth
device (i.e. RS232 in not multidrop bus). With this "SoarTronic"
you do not need that switch, and these two animals can live
together in RS232 line - as long as they do not speak
simultaneously. This is idea of Simon. I also think that if you
have your FLARM connected to Variometer or VW1150, you can
add this device into the FLARM RS232/power cable. This device
does not have CanBus build in it, but you can connect any
RS232/bluetooth module in the RS232 connector of VW1150.

We have had many gliderpilots involved in this project. It
actually started as a spinn-off. We were (and still are)
developing an interface board to Sparkfun IOIO board, that
connects 4 RS232 lines to Android phone over USB, and
provides 12V/5V conversion for charging the Android device. But
that is an another story.

How is the SoarTronic different from the K6 bt? The only thing I can see is
that it uses the 3V connection of the FLARM RJ-45 jack instead of the jack's
12V connection.
http://www.cumulus-soaring.com/k6.htm

I have tested a K6 bt with my iPAQ hx 4700 running LK8000 and my Android
Atrix running XCSoar. It works great in both cases.
