I've already explained. I'm trying to get my OSD, my Flight controller, my telemetry to get to work with one GPS.
When using MTK utility for setting the GPS, it gives an overhead in procentage, when you set the baud rate. And it doesent allow to set any update rates higher than 2HZ for 9600baud... I'am not sure that the sentence is 72bytes, i do believe it's much, much larger.
