This is about 5 miles of light highway riding on street rims and 15/44 gearing, took basically exactly 10% battery.

Of course! I think I might have posted some of this elsewhere on the forums but I can't remember where right now. Eventually the app will be open source but for now I can share just the relevant Bluetooth interface. This should be enough to grab service & characteristic IDs from plus shows how...

Thanks to Erwin's feedback I've added a few alerts to the battery page that will display when things are obviously wrong. The main conditions involve the cell group voltage, cell group deviance from the average pack voltage, and overall pack voltage delta. I can't say for sure which of these...

It should work, instead of using the KMH reported by the VCU (and adjusted based on your unit) it simply multiplies the RPM by a fixed number you provide. This calculation should be done using KM/H as the unit adjustment comes after. I believe the stock gear ratio with this setting would be...

On Android its the normal play store update process; 1.2.0 build 18 is the latest. On iOS you need to open the Test Flight app and update from there; 1.2.0 build 85 is the latest.

An updated version of the app is now available on both platforms for testing, only two main things to test here: - Updated the dashboard screen for Android to fix the speedometer overflowing and a few other spacing/display issues. - Reworked how the underlying recording format works to make it...

FWIW I assume the pack layout is the same so its very common for the first, last, and middle two (50/51 in the app) cell groups to be farther out, these are the ends of the two pack halves so they dip a bit compared to the others. Anything below .015 on a full charge I would consider very...

His delta V is so low I assume his cell groups are reading normally. Really does seem like your pack has two cell groups out, still very surprising to me that doesn't trigger a BMS fault or other warning on the display. There is a versions page in the service menu that displays all the...

Interesting, I can't promise everything is compatible with the MX series, from what I understand the app for it (unless its been updated to match the EX one) uses a different Bluetooth interface/version. Given that it's possible some data is incorrect or nonsense on the MX series. I do believe...

Huh, I was wondering why I saw the VCU listing firmware versions for things like the front/rear light and map switch. I guess pretty much everything on the bike is powered by a custom circuit with a microcontroller and Stark firmware? It would make sense that most things communicate via CAN...

Ah one other thing I thought of on this point, I am relatively sure most of this data is available over the OBDII/diagnostics interface. It'd be cool to eventually poke at that but honestly I've been too lazy to pull the plastics off and find the connector. If the data is available it'd make...

While I will probably eventually investigate editing charging rates and maybe some basic settings, the map settings is a bit trickier issue. I suspect that the VCU has no concept of whether a bike is configured for 60 or 80hp, and since I can't actually read data from your Stark account it would...

Thanks! The screenshot is very helpful, I'll keep working on getting the display of items fixed for different screen-sizes and layouts.

Interesting, are you on an EX or MX? My guess is these readings are wrong as that low of a cell voltage is basically impossible (unless the connection to the cells is severed completely). It's also very suspicious that both readings are so close to eachother, and they also look like a delta...

Ok, I believe I've sorted that issue out as Google just defaults to US & UK for closed testing. I opened it up to the entire world so hopefully that lets you all see the app and install it now.

I'll take a look when I have a chance later this week, I guess Google is weird about some of this stuff. I thought about doing an Apple watch app since those can use Bluetooth but haven't really played with it at all yet. Eventually I'll get the code for the app open-sourced and then perhaps...

Ok well I suppose it was a bit foolish of me to think that was going to take any time at all, the build has been approved and should be available to those that join the group via the link. I'm not too familiar with the Play Store but I don't believe there is anyway to provide feedback so please...

The Android version is currently pending review by Google, it will hopefully be available for testing after they complete that review. If you'd like to join the Android "closed beta testing" group please visit this page. I'll post an update in this thread when the version is actually approved...

Thought this would be interesting to post as well even though its in early stages, this is a companion website to the app which supports uploading the tracks/recordings (however you want to call it) for visualization. At the moment all the data remains on your local machine and its designed for...

If you want you can play around with my beta iOS app which does display a ton more information from the VCU, and AFAIK shows pretty much everything you can see over the CANBUS/OBD interface but works over Bluetooth. Even then Stark doesn't have a ton of internal diagnostics data when it comes to...
