xgps: no data in "qual" and "prRes" with ZED-X20P

[Hans Mayer]

Yo Gary,
dear All,

My environment:
Raspberry Pi5 with Debian 13 and Python 3.13.5
xgps: Version 3.27.6~dev  ( commit 
df094cf5a83244c0724f87280e0bb541822284ce )
u-blox ZED-X20P with FWVER=HPG 2.02 and PROTVER=50.10

When I start
xgps -u m localhost:gpsd:/dev/serial0 &
I don't get any information on column "qual" and "prRes".

Do I need to prepare the ZED-X20P with some settings ?
Actually this is not necessary when I use any other u-blox's

Kind regards
Hans
