ZED F9P and Pixhawk 4

Hello!

I’m trying to connect a zed f9p module to pixkwak4 to use it as gps, but pixkwak4 doesn’t detect it and always marks it as ‘Not OK’.

The gps module works correctly as I have checked it with u-center.

Does anyone have any idea why it is failing?
Is there any specific configuration to connect the gps module to pixhawk?

Thanks for your help.
