    @Ze-Stuart Great question! It actually reminds me of how my deep dive into the Suunto ecosystem began. For me, these watches aren’t just sports gear; they are a technological puzzle - kind of like Sudoku, but with more hex code. After OpenSuuntoPlus launched, I was desperate for app examples to help me write my own. I decided to dig into the firmware, hoping to find the “real” apps hidden inside. I found several files, including a filesystem snapshot, but it wasn’t just a simple sequence of bytes. Instead, it was a massive pile of small blocks scrambled in a seemingly random order. To better understand the algorithm, I decided to learn what Ghidra was all about (having never used it before). I naively thought watch firmware would be small, simple, and easy to analyze. I was… overconfident, to say the least! However, it was incredibly productive. I spent time forming hypotheses, checking memory chip specs, and diving into SDKs for embedded OS memory management. I even managed to “de-fragment” a working disk image from those scattered blocks, though I’m pretty sure a few bugs are still lurking in there. Around that time, I realized the role SDSApplicationServer plays in the system. I shifted my focus to the JSON-based REST API it uses. I figured if the VS Code extension could manipulate watch data through it, I could too. Ultimately, using the server was a much faster way to get data off the watch, and it largely confirmed what I’d spent days piecing together from raw blocks. So, back to your question: Now that I have a better grasp of the architecture, I’ve been exploring how to communicate with the watch directly via the browser. Remembering my experience with Ghidra - and noting that the firmware is tiny compared to the SDSApplicationServer binary (which is dozens of megabytes!) - I haven’t quite summoned the courage to go back to this approach! Analyzing serial interface dumps feels more manageable; control commands are usually just dozens of bytes. The more you work with them, moving from simple to complex, the clearer it gets. There are still plenty of mysteries left, but that’s exactly why I enjoy this “Sudoku” - it keeps things interesting!

    @duffman19 said in Min. Sleep HR too high?: @raven This has been discussed before and, if I recall, the reason for the discrepancy is that the minimum sleep HR is actually the lowest average HR over a given time period (I think 10 minutes? not sure, though). This can obviously differ from the absolute lowest specific HR reading. Appreciate the context. Given that info, I still feel there’s an issue here. As one can see from what I presented, I think it’s easy to think there’s a conflict between “Min Sleep HR” and the lowest point of the graph. It may be there needs to be a different label, something like “low sleep trend” that indicates the value isn’t the lowest recorded, but whatever it’s meant to represent. As it is, it just looks like the system is “lying” to me when it tells me my low sleep HR was X but it’s always actually X-2, or X-4, etc.

    I can’t try until Sunday but I wanted to share if anybody wants to try, since I have an interesting answer from Komoot’s Thanks for sending the GPX file. I took a look and found a workaround that should help you save the full route: Click New > Import a GPS Route Drag and drop the GPX file Instead of selecting Import to Plan a Route, select Import as Activity Tap Import Activity This saves the file as a completed Activity on your account. On the map, the route should connect all the way to the end. After that: Click the three-dot icon on the right Select Make a Copy Click Save The copied route will be on the Saved Routes. It should then show the full route from the completed Activity, rather than being cut short like it was when imported directly as a planned route. You may, of course, delete the Completed Activity after. Let us know how it works for you. All the best, komoot Support Team So this solves the pre/post processing issues (perhaps) for the GAPs, and perhaps the offset thing. I’d like to test it now, but I’m out this weekend, lol.

    I guess the only way to get some more attention of Suunto on that topic is to write down about this situation on Suunto’s instagram and Facebook profiles, as here we just write about this issue among the the Ocean owners, we already spent our money… we are less interesting for them. Said true is that the future owners and future revenues are always much more important…

    I did not comment but I’m testing my Spark. So feedback post: Sound quality is really good. Build quality is very nice. They feel really premium. Not so good things: The touch is too sensitive. I have disabled by default the “one click” Audio notifications are exactly the same as without the Spark. I knew that, but I didn’t expect the latin american spanish for Spain. Metrics are not integrated with the watch. I think the S+ app should have two more options: An option to toggle on/off things like navigation audio indications, so users can decide if they want the navigation audio indications (which are very useful in several cases). For that, Suunto should implement the feature (which is still missing). An option to toggle on/off to use the metrics taken from the Spark’s pedometer in the main activity in the watch.I mean, to not have 2 activities in the app (watch and spark). Something similar that what happens when you are using a chest/arm strap. One activity with the much better bpm taken from the chest/armstrap, not two. Something similar happens here with the Spark, since you have 2 additional pedometers that are going to work a lot better than in a one moving arm. For someone that made the effort of buying the Spark, I see this as an important software bug that should be solved. Having 2 individual activities has not sense (at all). Ideally: Go further with a firmware update for using pedometers of the spark for indoor/treadmill runs, if possible of course. Things like voice notes while on workout (if possible). Just those little things for making the Spark a must and a perfect companion.

    Hey guys, could someone make HRV reading work? I do not get the values, even tough the Suunto Smart Belt is conencted. In the SImulator it says “undefined” for /HrvRmssd [image: 1778225463781-3b15736a-9e26-4429-b7f4-d9b54347d637-image.png]

    @Dimitrios-Kanellopoulos I wanted to mention that I had one crash a a few weeks ago, for which I had uploaded the logs, and the crash was then reported into the system with help of @Egika . In my case it was a vanilla Run sport with nothing special about it and me not doing anything with the watch at the time of the crash. The only special thing was, perhaps, is that I used the Run sport for the first time on the watch, but previously I did a number of activities with a customized Trail Run sport. If that helps, I can send you the details (crash time, etc) again in the chat.

    @Travis-Kinney said in Watch set to Imperial but I'm getting Kilometer splits: gives me is kilometer splits Choose exercise, before start scroll down to Exercise options > Autolap > Distance Choose the distance and unit, either Miles or Kilometers. Edit: Not sure if this applies to Suunto Run though.
