Hello
I have been trying to use FG and meanwhile to broadcast GPS NMEA position on my PC WIN7 BT com port (COM8).
It appears that 1- I found the correct set of parameters to add to the Launch command line --nmea,serial,out,1,COM8,4800, but when I launch FG with such set of parameters, the init of FG stops and remains stuck at "Position Initialization".
Log is available here (post #18 @ http://fr.flightgear.org/forums/viewtop ... 634#p39634 , first log is the one with --nmea parameters, second one is the one without where everything is OK. One can see that the last sentence of the --nmea log is :"view:3:G:\Jenkins\workspace\Windows-release\flightgear\src\Viewer\splash.cxx:678:Splash screen progress finalize-position")
But I discovered that if I launch an PC WIN app which has been designed by a French pilot (see here: http://francois.fouchet.free.fr/, there is a link for english speakers in the menu) before launching FG, FG is not stuck anymore during its initialization. Indeed, in this application aimed at preparing VFR flight navigation, there is an option to send to a port Com MNEA GPS position for a simulation mode - see here: https://drive.google.com/file/d/0B-Weut ... sp=sharing) -
Doing so and launching for a while this simulation mode, then exiting the app and launching FG: FG is happy and passes all initialization steps with --nmea parameters
I am not a PC software expert but it seems that Navigation software sets parameters or variables for port com management or other stuffs in windows which are retained even if the application is exited, and it seems that FG is benefiting from these parameters/variables to init itself OK
Is it a know issue - I have seen somewhere else on the forum that "Position Initialization" stuck were already observed, and would it be possible to add to the launch of FG the adequate set of parameters (identical to Navigation App ?) to allow a good behavior along with --nmea parameters ?
Thanks in advance for any help
