Sunnto 7 Sensor Support
-
@jamie-bg in talking about this in the forum previously I believe there may actually be a hardware limitation in regards to sensor support within the Suunto fitness app on the watch. Being the coprocessor does most of the heavy lifting when using the built in sunnto app it may be the limiting factor in terms of connecting a Bluetooth sensor. I could be wrong however that’s how it was put to me by one of the moderators on this forum. I agree with you though in that adding that features would make the Suunto 7 the best smart watch/training watch on the market.

@brotzfrog10 - if can connect using sportygo, ghostracer, and GFit, it means it is feasible on the Suunto app. Note that I said I believe the concerns are in regards to battery life, but if you got a warning prior to using it stating this would be heavy on battery life, users then shouldn’t complain about the additional feature’s battery cost, as you know what its going to cost you to use it.
I sincerely do believe that most people complain due to the unexpected. Sure there are always some very unreasonable people.who complain no matter what, but I think that most of us only complain when its unexpected. I.e. if normally get 8%/hr, then add in external HR and its suddenly 20%/hr - yes you going to complain. But if there is a switch or something that you have to flick to allow this connectivity, and the warning says that using this feature causes heavy battery drain - how many of us are really going to complain (other than those who are unreasonable).
-
@jamie-bg there could even be another setting, that would make use of the Suunto Smart belt’s caching capability.
So the watch would pull HR not in real time, but every 20secs or so and inbetween switch to low power coprocessor… If one does not need instant heart rate but more the tracking and after training analysis it could even sync only once training is finished.

@egika only problem with this would be active HR metering.
This is very important to me and have found it super useful for my fitness improvement.
I am fairly limited in what and where I can go for the moment to improve fitness, so am unfortunately having to rely on a couple of the same courses, however with the zone metering I can tell when I am coasting and can use that to push harder, or pull back when I am pushing too hard to prevent injuries (body is really beaten up so I can injure myself fairly easily).And while I agree your idea certainly has merit and would be a good start/option, I think most would agree they would prefer to see active feedback as they perform.

They already offer always on map display as an option along with a battery warning. So they’ve already done something similar.

Before Google killed of Google Play Music, I used to use it on the S7 to stream music to my Bluetooth headphones without having to take my phone with me.
This resulted in the S7 not switching to the coprocessor and therefore battery life taking a hit.Essentially I am saying there is nothing hardware limiting the use of an external Bluetooth device whilst the Suunto App is running.
Yes, battery life is impacted, but as others have mentioned a warning message would be enough inform users.Suunto 7 Graphite Copper

@jamie-bg of course there should be current live HR display. That is why I wrote “another setting” that could be used by people who don’t need live HR data.
When I am riding my mountain bike, I am using the map display.
the watch logging distance, speed, HR etc does not matter. Still it could use the belt to sync data to the watch after the workout for the record. -

-
@aleksander-h My AirPods Pro work fairly well.
-
@brad_olwin headphones problem then I guess. I know the 65t have their ble antenne in the right ear, so I guess that’s the issue. Oh well, I’ll just use it on my right wrist until it’s time to replace them. Thanks for feedback.
-
@jamie-bg Just to further clarify my point, from what I gathered from one of the moderates, Suunto made it so their own training app ran through the coprocessor on the watch in order to stretch battery life while training especially gps routes. Sportygo and other apps aren’t engineered in that same manner and run on the main processor of the watch which there for may allow them more options when it comes to connecting to sensors.

I use Aftershox Aeropex and they work really well and I could even be in the next room and still maintain a stable connection.

@jamie-bg this is a reply I got from a moderator back in January about the coprocessor and a Bluetooth heart rate monitor, within this very topic of the forum.

Maybe the coprocessor sunnto is running the training app off of can’t do those kind of connections?

Correct. They are able to disable this though. For instance when you look at the map it goes from that black-and-white arrow to a full blown map. From what I gather, this is the app moving over to the non-power saving core(s). I’m guessing if you turn on the always on map function from settings, the app probably stays in high power mode throughout the exercise (as long as you have the map screen open).
[Edit] I could be completely wrong though
-
@aleksander-h you are correct, the main processor is woken when you use the map, when laps are triggered, etc. Those are battery hits, but usually they happen only once in a while. Connecting to BLE means having the main processor working all the time.

Oh, laps as well? That’s interesting.
The more I hear about how it works the more I wish I worked there
. Oh well. Back to debugging 1990s enteprise software… -
@aleksander-h laps are the thing I am not 100% sure about, but it should be.
-
@aleksander-h yes - if you look at you watch post the auto lap notification you will notice that the Active Hr zones are slightly thicker than usual - which of course means the main coprocessor is active.

@brotzfrog10 i love the watch both as sport watch and smart watch but the lack of external sensor is a huge disappointment since i do different kinds of sport in tennis sometimes it looses its accuracy and u do kick boxing and for that i have to use my old m5 suunto watch SUUNTO PLZZZZZ ADD EXTERNAL BELT FOR SUUNTO 7

I run with S7 and a Stryd Power Meter.
On completion, I offline-sync the Power Meter, export the ‘power data only’ GPX, and in GoldenCheetah, import, merge and crop (if I for example finish my activity on the Watch, the Power Meter is still recording movement if I walk quickly) with the regular activity data that has synced there from SA or Strava or somewhere, export, and upload to TrainingPeaks and Runalyze. Takes me less than a minute end to end.
I think Suunto COULD theoretically do this post-activity merging automatically, given Stryd can be linked as a ‘partner app’ and they seem to do this with other watch models…I’d like to see if THIS does exactly how I interpret it >>
Suunto >> “When you sync your watch with Suunto App after a run and then sync your Stryd with the Stryd app, you can take advantage of a variety of other unique metrics measured directly from the foot: form power, ground contact time, leg spring stiffness, vertical oscillation, and wind power. Again, to get Stryd+ metrics you must do an offline sync that merges your watch data to the pod data.”
=
Run with Watch and paired power meter - some basic power data included directly in the activity? Then do a Stryd Offline Sync, so you get all that extra Wind/Stiffness data etc into Stryd. And the SA either polls or gets pushed from Stryd all that extra data and merges it into the existing activity, so you can see it all in SA on phone??
