PGN 130822

Related to this issue: canboat/canboat#10

Should signalk continue to pass it through up the chain? Or since we don't know what it is, just forget about it?

Since we don't know about it, we would not put it in Signal K.

It would first need to be added to canboat.

More of these, sent by a Simrad AP44 (autopilot controller screen). These were sent when the AP44 and autopilot were idle, and quite some time after startup.

Put together (they're fast packets)

Some observations

• The sequence [00-02], [20-22] ... [E0-E2] repeat.
• Each sequence takes about 4 seconds
• The time between sequences is arbitrary
• The repeating sequences are not identical, and since my test bench is completely static (fixed rudder sensor, idle AP state, no Precision 9 or GPS). Maybe a counter or time, or perhaps something related to a security measure?

[fabdrol]

@tkurki back in 2014 you were hoping for the 'internet of minds' to figure this out, but we don't seem to be getting anywhere!

[htool]

@lfrancois Did you get any further with this? I'm trying to emulate presence of an AP44 on my network to make the Triton2 display autopilot state (which I'll feed from the Raymarine autopilot state).

[htool]

Did is what my B&G Triton2 does on that PGN:

ff 01 00 0a 00 00 fc 13 b6 00 00 94 3a
ff 01 00 0b 00 00 fc 13 b9 00 00 16 67
ff 01 00 0c 00 00 fc 13 6f 00 00 03 bb
ff 01 00 0d 00 00 fc 13 25 00 00 74 be
ff 01 00 0e 00 00 fc 13 25 00 00 74 be
ff 01 00 0f 00 00 fc 13 60 04 00 a3 5c

It looks like the 0a..0f are field and the fc 13 some values. I'm guessing some diagnostics/version info which is not actively used.

[htool]

Actually, it's this:

ff 01 00 0a 00 00 fc 13 b6 00 00 94 3a
ff 01 00 0b 00 00 fc 13 b9 00 00 16 67
ff 01 00 0c 00 00 fc 13 6f 00 00 03 bb
ff 01 00 0d 00 00 fc 13 25 00 00 74 be
ff 01 00 0e 00 00 fc 13 25 00 00 74 be
ff 01 00 0f 00 00 fc 13 60 04 00 a3 5c
ff 01 00 09 00 02 fc 12 1c 00 00 2f da

And every time it repeats it's the same. Is see it when a new device comes 'online'.

[htool]

I just made my software AP44 send the message you captured. This triggers the Triton2 to send the following:
2020-02-01-19:54:58.203 3 0 255 130822 Manufacturer Proprietary fast-packet non-addressed: Manufacturer Code = Navico; Industry Code = Marine; Data = ff 06 00 09 00 02 fc 1c 00 00 2f da 01 00 04 00 00 f0 41 01 00 00 01 00 01 01 01 00 04 00 00 00 00 01 00 04 78 00 00 00
