Hello Kimmo, Kimmo Hytoenen wrote: 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. 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.

Power FLARM question
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. Wayne http://www.soaridaho.com/ "Kimmo Hytoenen" wrote in message . com...

Regards Chris 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. |

I already have one K6Bt for my 302 (works perfect), and rather not spending the same amount on another K6Bt. Ramy |

It needs a 5V power source either via USB cable or external battery. The Flarm provides a 3V output, I guess that would not be enough to power the device. Kimmos and my device work with the 3V directly, that saves some hardware. I don't know if the K6-BT works similar. Chris |

Also, if you use external display, this works nicely with that. -kimmo |

Power FLARM question
From what I've understood so far, there is one important difference between SoarTronic and the K6BT, which is baudrate switching. The K6BT has a protocol to let the connected software change the baudrate of the adapter and I haven't seen any other devices yet, that are able to do that. XCSoar has recently implemented that protocol which makes it easy to change the baudrate for IGC file downloads for example. The Flarm does not need this feature since it doesn't have to change the baudrate, but my DX50 (similar to LX5000) sends GPS data at 4800 yet the transfer mode for upload/download works at 19200.
