Yes this issue with the Bravo LEDs appears to have frustrated many simmers including myself since receiving my Honeycomb Bravo Throttle Quadrant. In my case I found that the instalation program for the AFC_Bridge failed to create the properly formated MSFS EXE.xml file required to startup the AFC_Bridge application whenever the sim is started. Before researching this issue I knew nothing about the existance of this file and its purpose. There are several postings on this forum that address this issue. However the process of editing .xml files itself can be challenging along with the unfamiliar formating used within its contents. I have managed to create a working EXE.xml file but I do not think that this is the way to go.
I feel strongly that there should be a user interface within the sim for creating this file in the first place. But that has not been done.
Fortunately there is a an option in the “MSFS Addons Linker” utility to start other applications when MSFS is started. Since the AFC_ Bridge app must be run after the Simconnnect is available it is necessary under the “Additional options” tab to check the option to “Wait until Simconnect is available before launching programs”. After that it is simply a matter of adding startup apps by navigating to their executable location on your PC using Explorer. No typing required! No messing with MSFS .xml files! I believe this is by far the simplest way to get the Bravo LEDs to run automatically when the sim is started along with other possible apps, and that utility is also a must have for organizing your community files.
Hope that helps get your LEDs to work without having to manually start the AFC_ Bridge application every time you run the sim.
