I'm having a heck of a time getting the Ground Station's two ends to connect to each other. I've checked the BTU module and it works fine when connected directly to the PMU. But, when connected to the Ground End it shows a solid red light. The G-End itself has two leds: one blinks green 5 times and the other is solid red. On the Air-end I have a blinking green light and a solid red. The iPad GS cannot connect to the aircraft. I'm stumped! Tuesday update: thanks to excellent very-early-morning assistance from EMCSQAR, the Ground Station is up and running! The problem was my ignorance of how to activate the iPad GS app. As the saying goes, "It's so easy when you know how." And when you don't know how... not so easy. :?
