Incomplete N2K PGN 126996
Hello,
The HW/SW is
- SignalK 2.11.0 (N2K addess 0x64)
- RPI 5 8Gb + SDD + PICAN-M
- Garmin MFD (N2K address 0x00)
- Own RPI Pico develoment (N2K address 0x77)
When the garmin ask for PGN 0x1F014 or 126996, the Signalk server send an incomplete message.
Should I increase a buffer ??
Details:
The garmin request produt information

As you can see, the message suppose to be 134bytes long but in reality is 77bytes long.
If I compare with other devices the message is 134bytes and understood by the garmin
