Alarm signal for interval training on Hammerhead/Xert

[OlafVenherm]

Hello everyone. As the title suggests, I’m looking for a way to set an alarm at the start or end of a single interval on the Hammerhead. Can anyone help me with this?

Question: Hammerhead karoo 3 integration

You are right, probably magic buckets should be the best for outdoor workouts so I’ll try that feature when I have bought the karoo. Today I also got an answer from the hammerhead support to my question concerning the sounds: the karoo speaker cannot be accessed by extensions and other apps due to software limitiations of the karoo system. another way to avoid that problem is to download the workout as ZWO file to the device and play it from the karoo system.

FYI extensions can play audio on the Karoo. Random example: GearBeeper for Karoo | Port City Creations

You’ll need to clarify with SRAM support if audio is now available to foreground extensions as GearBeeper states it “runs as a background extension”.
That may be the limitation.
Also, EBC Android relies on Media volume for interval tones.
Is that different than what GearBeeper is using?
