Shimano Di2

[zucchero]

@Raimo-Järvi Thank you for the info. I’m using iOS 17.5.1

I found an other issue with the Shimano Di2 app:

When I start Bicycling (Basic) with SHIMANO Di2 switched OFF in the SuuntoPlus Sports Apps, then there is nevertheless the screen for SHIMANO Di2 right after the screen with the map. The SHIMANO Di2 screen shows no data, about what I’m not surprised, because I wasn’t asked to connect.

When will all these issues be fixed?

@zucchero Did you have “SuuntoPlus: None” shown in workout menu before starting the workout?

See my reply in e-bike app thread, Bluetooth issue is the same in both Shimano apps:

Hi,

I have found that the Shimano Di2 App is not remembered after being used in a Cycling (basic) activity.

According to the SuuntoPlus FAQ:

Note: The SuuntoPlus sports app you select for an exercise will be remembered on the watch for future uses of that same sport mode - i.e. it will be automatically selected when you start another exercise with the same sport mode. You can de-select it or change it before starting as usual.

But next time I am about to start a Cycling (basic) activity, the options shows SuuntoPlus: None.

I am using a Suunto 9 and I really hope this will be fixed in a future update (wishful thinking?).

Cheers!

Are you saying that other SuuntoPlus apps are remembered, but not Shimano Di2? I think only newer watches remember the app, but not Suunto 9.

Hi @Raimo-Järvi,

I did a quick test enabling the Cooper Test SuuntoPlus App in a Running (basic) activity and the same thing happen (not remembered in a new Running (basic) activity).

So, as you say, Suunto Plus Apps are not remembered in Suunto 9 watches.

I would be nice though, in case Suunto is still maintaining this watch

Cheers!

[Raimo Järvi]

@wachutunai Thank you for confirming that. Suunto 9 received its latest software update on June 28th, 2023. Even if there would be an update for it in the future, I don’t think remembering SuuntoPlus apps will be included in it.

Hello,

I am experiencing the exact same problem as @zucchero. Has this issue been resolved? I am using the Suunto Race with the Shimano BT-DN110 Di2 Battery (Shimano RD-RX815 + Shimano GRX Di2 RX815).

I tried in discovery mode and then tried waking up the Di2 system, but it didn’t work.

Any tips? @Raimo-Järvi

[Raimo Järvi]

@Wilderlicht BLE issue with Shimano devices should have been fixed in software update 2.37.34. What is your Suunto Race software version?

[Wilderlicht]

@Raimo-Järvi ! The version on my suunto is V2.37.34.

[Raimo Järvi]

@Wilderlicht Then I don’t know what the problem is. You could try restarting the watch, probably doesn’t help but worth trying.

SuuntoPlus store says Di2 app has been last updated in June. @pavel-samokha Could you check that latest Shimano apps have been activated in SuuntoPlus store?

[pavel.samokha]

@Raimo-Järvi No, they were not. Activated now, thanks!

Will there be something similar for SRAM AXS ?? Would be great.

[Egika]

@Stoke80 has been discussed before. not possible, as SRAM does not open their protocol for external development

[Ze Stuart]

@Egika surely we could have gear and battery information recorded and displayed? Garmin and Wahoo both do this for SRAM.

then SRAM opened their communication for those companies. Not so for Suunto.

Battery information is probably a standard BLE service, but gear information is in SRAM specific format / protocol.

@Wilderlicht You could try again now that SuuntoPlus Di2 app has been updated.

[Wilderlicht]

@Raimo-Järvi Thank you, it works

When I start a new Cycling training, the DI2 is shown in the Suunto plus menu.
But nevertheless, I have to activate it manually in that menu every time before I start the training (even when it was used in the last training session).

Is that the normal behavior?

[wachutunai]

Hi,

My Suunto 9 crashes every time I enable the Shimano Di2 App in a cycling activity.

I managed to isolate the problem by starting a cycling activity with no sensors connected, that is, no GPS, HR belt/wrist, power meter, cadence/speed.

As soon as the Shimano Di2 App is enabled in a cycling activity, with or without other sensors connected, the watch crashes (and soft resets) after a couple of seconds from starting the activity.

Any other connected sensors combination in a cycling activity works without issue (GPS + HR belt + Power, or GPS + Power + Speed , etc.).

This behaviour is consistent and happens every single time I enable the Shimano Di2 App.

It started about a week or so ago but worked fine in the many cycling activities that I have recorded in the past with the Di2 App enabled.

I have tried without success:

• Soft reset the watch.
• Re-pairing all sensors.
• Hard reset the watch.

I run the latest firmware in my Shimano Ultegra 12 speed set-up:

• RD-R8150: version 4.2.3
• FD-R8150: version 4.1.1
• ST-R8170: version 4.2.2
• BT-DN300: version 4.2.0

Any guidance would be much appreciated.

Cheers!
