Describe the bug A clear and concise description of what the bug is that I used UBlox ZED-F9P and recently I use ntrip caster here: https://github.com/LORD-MicroStrain/ntrip_client/issues/29#issuecomment-1572711569 I can publish the RTCM msg, but the problem was how can I use my Ublox F9P to use those RTCM messages? To Reproduce Steps to reproduce the behavior:

  1. My RTCM rostopic was: /ntrip_client/rtcm, and I added it here: I added my RTCM rostopic here: https://github.com/KumarRobotics/ublox/blob/4f107f3b82135160a1aca3ef0689fd119199bbef/ublox_gps/src/node.cpp#L1908 H However, when I checked my gps rostopic: /ublox_gps/fix, the status was always 0, which means I did not get RTK solution. Do you have any idea about that?

Besides, when I ran the ROS driver then I got the error here: U-Blox message exceeds maximum payload length 8184:0Xa1/0XB3, do you have any idea about that? I found the script here: https://github.com/KumarRobotics/ublox/blob/master/ublox_serialization/include/ublox/serialization.h#L61 But even if I increased the value from 8184 it did not help. Could you please give me some ideas? Thx

Hey!

Is this issue resolved? Have you managed to get RTK fix?

I am using ZED-F9P with RTK. It works for me. Try this NTRIP Client
