NTRIP 4G client configuration

Q&A forumCategory: QuestionsNTRIP 4G client configuration
dcanton1995 asked 1 month ago
Good afternoon
I have been trying to configure one simpleRTK2B V3 with a NTRIP 4G, and after configurating all the board, we are struggling with the 4G NTRIP client configuration.
The board is receiving GPS signal without problems, but the messages that it is receiving from the 4G client doesn’t correct the position with a RTK precision.
After several tries we have figured out that the problem must be on the 4G client configuration, the NO RTK led is permanetly on.
We have tried to connect to the NTRIP client through the u-center app, and we don’t have any problems to connect with our credentials, we are receiving correcions, but the 4G client is still sending the message:
$GPTXT,WARNING: NO INPUT STREAMS FROM NTRIP SERVER IN 10s, PLEASE CHECK CREDENTIALS AND GPS RECEIVER CONFIGURATION*66

I am attaching the Log after setting the parameter: $$$AS+D=1 if it could help
 
Thanks in advance

Hi dcanton,

Problem is usually not sending GGA to server. You need to enable on zed-f9p GGA at 115’200bps in the interface connected to the 4G NTRIP.

Once this is solved you will face another problem from the configuration above, zed-f9p works better with CERCANA3 mountpoint.

I have tried your solution but it is still not working,

On UBX-CFG-MSG the message: F0-00 NMEA GXGGA all parameters are set as 1
On UBX-CFG-PRT UART1 is set with the protocol “in” as RTCM3 and baudrate as 115200.

And the moutpoint has been changed to CERCANA3 as well

Would be great if after the changes you could post again a logfile like you did above.

Did you resolve it?
