Keeps crashing on windows 10 about watchflower HOT 13 CLOSED

Thanks for the detailed report guys.
So far I have never be able to reproduce that crash, but many people complained so I'll have another look at this soon.

last edit :D  it seems that wf 1.0 has qt 5.15 onboard. maybe an update to 6.1. works? :)

Qt 6 does not have any bluetooth support at all, so probably not ^^

Haven't had any issues with crashing on version 4.0 yet. I will leave it running for a few days to verify.

hi! i have the same problem here (win 10 home 20H2 with newest system + driver updates) :/ Qt5Bluetooth.dll error in the windows event viewer and the app crashes all 2-3 hours.. i thought the problem is my device (so thx for your ticket!), but i already did a fresh windows 10 pro install and also installed wf 1.0 afterwards -> still the same problem... i couldn't find any information about "Qt5Bluetooth.dll" but already tried to give all windows users/admin&user-account all rights for this file... this didn't solved the problem :/

fyi: i use watchflower for windows for a few months now, and the problem persists since v0.15... i solved this issue by installing VNC-server on the device and restart the app every day when i remote check the sensors and because of the reason (offtopic content following), that i have to manually "search for bluetooth devices" (in windows) and while searching click "refresh data" in the app (otherwise ~50-100% sensors can't be refreshed) to get actual data for all sensors, i didn't wrote a ticket by myself and thought it is also a good everyday-workflow and thought posting 2 problems will not lead to the solution or my device is the problem... :) the problem with the "manuel search for devices" in windows was double checked with 3 different BT-devices/sticks (on the android app/device next to the windows-machine it works without problems - just sometimes problems with one or two of the sensors that are over ~8m away)

I also already deactivated all energy saving options in windows (from the usb-hub driver over the BT 5.0 stick driver to all windows settings + bios options).. maybe this information helps to fix the Qt5Bluetooth.dll problem

I have another issue with the Bluetooth connection between Wins 10 PC.
Any guys encounter PC can view parrot pot on the Bluetooth list but can't connect successfully.
Only my Ipad can success so far

This issue was originally reported for WatchFlower version 1.0, but just I found the software, already on version 2.0. I have a similar problem with Windows 10. WatchFlower may start nicely and work for an hour (until next BLE update), or may hang right at the start so that I need to restart it a few times until it just starts to work again. For Bluetooth I'm using whatever Lenovo put inside a Thinkpad and default drivers. Two MiFlora sticks with firmware 3.2.4.

@janilahti i posted the problem before, but it persists in v2.0 too... can you maybe check if you use a realtek bluetooth driver on your thinkpad? the past few weeks i read a few times that win 10 realtek-driver can cause problems with the automatic installed microsoft-provided realtek-driver... but i wasn't able to find a solution.. i tried a) the realtek bt onboard driver on my hp 250 g4 notebook and three different BT-usb-sticks 4.0 and 5.0... the only thing i found out: all of the bought usb-dongles have realtek chips inside;)

1. i tried the original hp 250 g4 realtek driver from hp directly, also checked this one with driverbooster -> still application crash
2. i tried to update the hp 250 g4 driver with "driverbooster" (i know it's not the best software/manufacturer, but it does what it shall do). the tool detects the correct chip and installs the newester driver -> still crash
3. i tried on all 3 BT-USB-sticks at first:
   3.1 the driver provided by the sellers -> still crash
   3.2. on all the sticks the same thing with driverbooster-driverupdate (before this -> clean-driver-deinstallation + restart) -> still crash
4. i also tried to check the hardware-id of each stick and tried to find an "official" driver (eg. USB\VID_0BDA&PID_8771&REV_0200
   ) -> searched in on google to find out the chip MPN/model -> should be RTL8671B -> no driver from realtek directly: https://www.realtek.com/en/component/zoo/advanced-search/57475?Itemid=276

@emericg wrote that there are more users with the same problem with qt 5.15 and bluetooth.. but i am too stupid to understand and find something in jira (https://bugreports.qt.io/browse/QTBUG-94001?jql=text%20~%20bluetooth%20ORDER%20BY%20created%20DESC) and don't know anything more about "QT" :)

i still hope @emericg finds a solution and maybe he can tell us what causes/caused the problem :)

edit: in v2 i get tow different errors in the event viewer but maybe the reason for crash #1 is https://i.imgur.com/5xr2ysp.png

@emericg https://wiki.qt.io/New_Features_in_Qt_6.2 juhu :) "The Qt Bluetooth module has been ported to Qt 6 and the CMake build system".. will this help?

[edit] today i installed ubuntu (multiboot) and now the app works fine :)

I am having the same issue with WatchFlower 3.1 constantly crashing. I am showing the same Qt5Bluetooth.dll error in the windows application event log reported by the OP (included below). I am not familiar with the QT framework, but doing some searching I think there are others who have reported similar issues with the bluetooth implementation and referenced potential workarounds. I could be way off the mark though.

Can you guys give the 4.0 version a go?

You can download it from the CI builders:

Issue still seems to be present, but it occurs with much less frequency. I can't seem to make it 24 hours without a crash, but before it was crashing every other sync attempt.

Well I guess that's progress :)
Thanks for testing!

I'm closing this thread, as the "keep crashing" parts seems fixed at least. I'll keep an eye on the "crash after 24h hours eventually", as it as been reported a couple of times.
