Add combined Flight Attendant status bar with position and mode indicators

[p18dh28ejfi]

I'm using a hardtail setup with the Flight Attendant system, and currently, I'm interested in two key pieces of information:

1. Current position: open / pedal / locked
2. Current mode: manual / auto

To display both values on Karoo, I need two separate data fields, which takes up too much screen space. While it's likely that the Karoo API doesn't yet support Flight Attendant data, I'd like to submit this feature request ahead of time.

Proposal
Add a compact, combined status bar (reusing the power bar framework) that displays both values simultaneously, similar to a mockup I’ve imagined:

• Bottom-left: Position indicator (1)
• Bottom-right: Mode indicator (2)

Suggested color coding:

• Position:
  • Open → green
  • Pedal → yellow
  • Locked → red
• Mode:
  • Manual → red
  • Auto → green

This wouldn't be a "power" bar per se, but it would leverage the existing bar framework effectively. Scrolling/moving text fields for these states would be less practical and harder to read quickly.

This compact visual feedback would be extremely useful for hardtail riders who want at-a-glance status without cluttering the display.

Great suggestion. I think they are currently not part of the public data types exposed via the Karoo SDK: https://hammerheadnav.github.io/karoo-ext/karoo-ext/io.hammerhead.karooext.models/-data-type/-type/index.html . However, they very likely are already available if you know the identifiers. E. g. the workout target data fields are also not mentioned in the docs.

I don't have a bike with flight attendant atm, but it should be possible to look up the datafield type ids just by adding them to a ride profile; I'll try that.

I'm happy to try out any test builds with my flight attendant😁

Type IDs:

• TYPE_SUSPENSION_STATE_REAR_ID for rear position
• TYPE_SUSPENSION_STATE_FRONT_ID for front position
• TYPE_SUSPENSION_MODE_ID for mode
• Others like TYPE_SUSPENSION_EFFORT_ZONE_ID could be added later

I'll have to check which numerical value in the data field corresponds to the values. But I guess it will be something like 0 = Open, 1 = Pedal, 2 = Locked for the states and 0 = Manual, 1 = Auto for mode

Interested in this as well! I'm available as a beta tester as well...

It is a bit difficult to implement things like this unfortunately, as they are not documented by Hammerhead and I don't have a flight attendant system to test with. Also, they currently have better things to do than answer little questions like this if I send them over; I get a reply once every few months. Back when they were introducing the new SDK, you could ask questions directly on the github tracker and the devs would respond, but they have removed that option.

Using a mocked extension device, I was able to verify that:

• TYPE_SUSPENSION_STATE_REAR_ID has a data field FIELD_SUSPENSION_STATE_REAR_ID where 0 = Open, 1 = Pedal, 2 = Locked as expected
• I assume it's the same for front state
• TYPE_SUSPENSION_MODE_ID has a data field FIELD_SUSPENSION_MODE_ID where 0 = Startup, 1 = Auto, 2 = Override, 3 = Safety, 4 = Manual, 5 = Bias, 6 = Fork LSC, 7 = RS LSC, 8 = Calibrating

Implementing it with this information should be easy.

I've pushed an update to version 1.6 that adds data sources for flight attendant fork position, rear shock position and mode. Using the "split" mode for the powerbar at the top edge of the screen, you can have the mode on the left and position on the right. The bar itself will always be at position "0", but show the value on the label.

Please let me know if it's working as intended.

Wow that was fast!
So I installed the update, tested shortly in the garage and it looks like it's working as intended! I confirm it works for both front and rear, and was also able to have the OVERRIDE mode displayed.
I will have to test ride it to confirm, but so far so good... Thanks!!

Cool, thx for testing. Please reopen if there are issues with it.

I tested it for several days and it's so awesome! Thank you so much for implementing this! It saves me two data fields on the main screen!

hi, do you think it should be possible to also add the Flight Attendant Effort Zone metric?

[timklge]

Yes, Hammerhead has also added that to the SDK. What is its value range?
