RTK not working outside of QGNSS for LG290P in Rover mode

IoT Modules GNSS Module

Hello,
With the QGNSS, my LG290P is working perfectly in Rover mode and GNGGA are received with 4 = Real Time Kinematic (RTK).

However, the same module, antenna not moved, same RTCM parameters, and connected in a RaspberryPi with Node-Red with my javascript code, the GNGGA are received as 2=Differential.

The LG290P return the confirmation that it is in rover mode with $PQTMCFGRCVRMODE,OK,1
The protocols are $PQTMCFGPROT,OK,1,1,00000007,00000007
I received all the NMEA message normally
I’m using an off the shelf node-red widget to get the NTRIP messages (same setting as in QGNSS) and the decoding of RTCM is correct as I can see 1005, 1033, 1077, 1087, 1097… messages decoded correctly
I’m sending the byte arrays of NTRIP to the LG290P. I have tried to send the full arrays and limited arrays of 64 bytes without any difference in results.
This is a typical GNGGA message received: $GNGGA,181613.600,4530.50249723,N,07351.24987288,W,2,34,0.58,28.821,M,-31.186,M,*7E

What step I’m missing ?

Forget about my last post; the buffer array handling between the NTRIP messages and sending the array to the LG290P was in problem. Now I get the R = Real Time Kinematic (RTK).
