Can't get H and V accuracy with antenna direct connexion (no mock location)

Hi,

I’m using an ardusimple F9p with 2 BT modules.
1 on UART1 receiving caster’s datas from an ntrip client
1 on UART2 to send corrected position by F9P to qfield
My configration is :

Port UART1
IN : UBX + NMEA + RTCM3
OUT : UBX + NMEA + RTCM3
messages : UBX-RXM RAWX, UBX-RXM SFRBX GGA, GLL, GSA, GSV, RMC, VTG, ZDA

Port UART2 :
IN : RTCM3
OUT : NMEA
messages : GGA, GLL, GSA, GSV, RMC, VTG, ZDA

when i active “actual position information” i can see data in HDOP and VDOP fields, but nothing in H and V accuracy.
I have tried to activate PVT messages, it works through usb in u-center but it does not work throught UART1/2 in Qfield.

Is there a message that I forgot to get the H/V accuracy ?

ewaca Add NMEA GST and you are solved !!!
Good work.
