Device on which you observed the bug:

Describe the bug Device disconnects immediately after connecting. I use the same code on 10 phones. 5 of them work perfectly, on the other ones, the polar devices cannot stay connected.

How to Reproduce Connect to the polar device, wait for 2 secs -> device disconnects

Expected behavior device stays connected

Hi @ThomasReyskens

May I assume that the phones you have observed the issue are having Android 13?

Here is the official statement related to H9 and H10 and Android13 compatibility issues:

"We are sorry to hear about this trouble with your heart rate sensor. The issue seems to be caused by the recent Android 13 update, and we are aware that the problem has been fixed already to certain phones like Samsung and Google Pixel, so please check first if there's a newer Android version available for your phone. It might solve the issue you’re experiencing. Despite of this, our team at Polar has been working on a solution for this issue as well to ensure all our customers get their sensors back to work with the Android 13, and therefore we will release a new firmware version for our heart rate sensors. The date is yet to be confirmed, but you will be notified about the update availability via Polar Flow and Beat apps and at the Updates at support.polar.com."

Hi @JOikarinen!

Almost all the devices where it doesn't work are indeed on Android 13. There is one: Pocophone F1 (Android 10) that also disconnects. But good to know that you are working on a fix :) Thanks for the clear explanation, looking forward to the update!

Hello there, this also happened to me with OPPO A54 and OnePlus 5T, apparently, also with Android 13 installed. However, on samsung mobiles with Android 13 this behavior is not reproduced. Looks like a issue with most chinese phones, namely with BBK Electronics-based phones (Realme, OnePlus, OPPO...). Maybe caused by their personalized Android systems (Color OS, MIUI, etc...)?

Hope the new version of the SDK is soon released. Thanks for the good work on it!
