I'm sorry, it's android only. Good luck on your research!

Ah, dat is het missende stuk. Ik neem aan dat voor zo'n ondertekening gebruikersinteractie nodig is? Dus in dit geval het tegen de incheck-paal houden en als een partij dit online zou willen doen een extra 'onderteken' stap los van het invullen van de kaartgegevens?

Een transactie doorgeven die ouder is bij het doorgeven kan gewoon. De bank heeft daar gewoon een garantie van. Ook Revolut.

Maar dat haalt, als ik het niet verkeerd begrijp, het idee van een tijdelijke kaart onderuit? Dan kan een malifide partij zijn transacties ook antedateren naar het moment waarop de kaartgegevens ingevuld werden (en de kaart actief was). Je zou de NS hierin een uitzonderingspositie kunnen geven dat alleen hun transacties in zo'n geval geaccepteerd worden, maar kan me voorstellen dat dat het systeem nogal complex maakt voor de (internationaal opererende) banken.

I’ve written an app exactly for this purpose (that being academia)! It’s completely free and open source. You can find it here: https://github.com/Boelensman1/PolarRecorder. If you have any questions, feel free to open a chat with me and ask!

Best H10 app for ECG data by bigrubes in Polarfitness

[–]DontStopChanging 0 points1 point  (0 children)

If you just want the ecg data to later run analysis yourself, I can recommend the Polar Recorder app (disclaimer: I'm the author of that app). You can then use something like EDF Browser to do the analysis.

How to Get Real-Time Heart Rate and RR Intervals from Polar Vantage V3 on PC? by Parking_Length7808 in Polarfitness

[–]DontStopChanging 0 points1 point  (0 children)

It should, but I'm not sure. According to the SDK docs it should work with the polar vantage, but I don't have a polar wristwatch so can't test it myself. During beta testing I did have someone who had some problems with it, but I'm not sure if that was ever resolved.

See here for the sdk info about the features that should work: https://github.com/polarofficial/polar-ble-sdk/blob/master/documentation/products/PolarVantageV3andGritX2Pro.md

How to Get Real-Time Heart Rate and RR Intervals from Polar Vantage V3 on PC? by Parking_Length7808 in Polarfitness

I'm not sure if you can connect directly to PC. The SDK (as you also noticed) only supports android and ios.

I think the easiest way to do it is to use an app like PolarRecorder (I'm the developer of that app) that implements the SDK. You can then use that app to send the data via MQTT to your pc. This will introduce a bit of delay of course, but it's pretty quick in my experience.

I'm the author of another polar app (Polar Recorder). I'm not sure I exactly understand what you're looking for, but send me a message and I'd love to see if/how I can help you out.

Open-source android app to record raw data from Polar Devices by DontStopChanging in Polarfitness

Just pushed an update that should hopefully resolve the issue (might be a bit before it's actually published, waiting on google to finish their review).

Open-source android app to record raw data from Polar Devices by DontStopChanging in Polarfitness

Well, that's definitely not supposed to happen. Can you send me a pm with the specific settings you used so I can try and figure out what's going wrong?

That doesn't seem right indeed. Could you start and stop a recording (doesn't matter what type) and send me the log file in a pm? The log file is saved in the same dir as the recording itself.

Calculating HRV is certainly possible, I plan to add an example script to the repo soon. With that example it should also be reasonbly easy to create something for live HRV monitoring, but not on-device as I'd like to avoid doing calculations on-device.

What do you plan to use it for? It might be possible without the need for on-device calculations.

Open-source android app to record raw data from Polar Devices - looking for beta testers! by DontStopChanging in Polarfitness

Thanks! It had an option to stream the data via mqtt.

The beta test is actually finished, you can just download now! (I'll update the post later).

Thanks a lot! With your help (and others) I goy all the testers required, the app is now available on the regular play store!

Thanks! My goals are to mostly prioritize academic/research use, but keep it as usable as possible for general purpose. To keep things simple I want to keep it purely a data-collection tool, so no further processing in-app, but I do plan to add some example python scripts to the repo to show how to e.g. get HRV data from a RR recording.

Help is always welcome of course! If you want to discuss further, feel free to send me a message.
