I have 14 sats and hdop 0.6 at my pixhawk and firmware 3.3,3 and mission planner shows this message
Home location could not update
I cant see how much far away is ny copter from home in mission planner
The rtl works as it should
My tellemetry unit could not show how much Rssi have between them ,they show nothing connect between them for rssi but i have the altitude value, the battery volts working as they should
When you say signal you mean the tellemetry signal?
If you mean the tellemetry signal i havent check the numbers but all the other data works good , the voltage , the altitude , the horizon ,the rssi of my controler
I solve it by changing my sdcard that i have inside pixhawk
I did some flights and everything work great
So if someone has a problem of not get home location update , or the tellemetry window keep running and never update values change your sd card with a new one
