NTRIP Client Checksums do not match RTCM msgs from PointPerfect Ublox Service #49

Closed akrv closed 4 months ago

I am using the Point Perfect service from Ublox to use their stream to get RTCM correction data. Installation works on ros2 but the checksum fails.

[ntrip_ros.py-1] [WARN] [1713113555.825503183] [ntrip_client]: Found packet, but checksums didn't match
[ntrip_ros.py-1] [WARN] [1713113555.826144931] [ntrip_client]: Expected Checksum: 0x622781
[ntrip_ros.py-1] [WARN] [1713113555.826787123] [ntrip_client]: Actual Checksum:   0x58C158
[ntrip_ros.py-1] [WARN] [1713113555.827552242] [ntrip_client]: Too much data buffered, trimming to 10240 bytes.

Any help would be appreciated.

Edit: point perfect service doesn't send RTCM3 data over the NTRIP client.
