i am a little bit confused regarding the leds of my apm. I use the APM 2.6 and the ublox gps module. As far as i understood the blue led on the apm 2.6 will blink if there is a gps fix.But shouldn't there also be a blue led on the gps module? There is only a red one at the moment. What i also do not understand: Will the apm arm without a valid gps signal? I was able to arm my copter with the blue led on the apm blinking and no blue led on the ublox.
if i take a look at my logs i can see a "0" at ”Nsats" ...
thanks a lot,
p.s: I did not yet understand the difference between a solid bue led on the apm and a blinking one. Can anybody please explain?
