QGC cannot get Holybro F9P RTK fix

Hi team,

I am trying to set up the Holybro F9P RTK modules on my drone, but it seems QGC cannot get RTK fix correctly. I have a couple of questions.

  1. For the base with antenna connecting to my Macbook Pro 2021, QGC can show the RTK logo, but it couldn’t get any satellites. And I could only get a normal 3D GPS fix showing down below.

I am using QGC 4.1.4 mac version.

  1. For the rover module on the drone, only the 3D fix light could blink during the flight.

I expected the RTK fix should blink on the left hand side. Also, for GPS driver version, I am using this one: GitHub - PX4/PX4-GPSDrivers at bcd57ae2396fe0fd88b725d81a686e072ef0ecc9. It’s committed on Apr 29, 2020.

So, can you please advise how could I enable the RTK fix with base module correctly? And where could I locate the log of the issue? Many thanks.
