Hi,
The Flarm radar functionality pushes me to possibly change the way I provide
GPS data to the device I use XCSoar with.
I am using XCSoar 6.1.alpha with an old iPaq 1950 (WM5, no internal GPS, no
bluetooth), connected via COM1 to an external GPS antenna. According
to the iPaq
plug description <http://pinouts.ru/PDA/ipaq_22p_pinout.shtml>, only one
serial input is available, which is presumably currently used by my antenna.
If I wish to use the Flarm radar function of XCSoar, I guess I need to get
the appropriate data from the Flarm (an original device with RJ45 et RJ12
plugs at the back). This appropriate data is the sentence PFLAU according to
the Flarm Dataport manual and available on both RJ45 and RJ12. Problem is
RJ45 is not available because it is used to power the Flarm device, and the
available RJ12 doesn't provide GPS "own" position.
My questions are:
- Can Flarm be used as a GPS position provider to XCSoar (sentences GPRMC or
GPGGA I guess), in place of current external GPS antenna?
- Does anyone ever tried to catch these data from the RJ45? (in order to get
the appropriate pins: 5 - Flarm TX and 7 - GND), what kind of assembly did
you use?
- Do you think the Flarm radar functionality requires more recent hardware
(with regards to performance),
- any simpler idea? (without changing my iPaq!)
Thanks
Nice flights
Adrien
