Bose SoundSport Pulse firmware 3.0.3
My earphones stoped working correctly, not sure if it is connected with the firmware version but I noticed the new version had been uploaded to the device a few days ago. They connect perfectly to the smartphone (huawei mate 20 lite) but heart rate sensor does not work with endomondo. This is not hardware problem because I can see on Bose Connect app on my phone my heart rate. When I scan for heart-rate monitor in endomond, it founds BoseSoundSportPulse device but is unable to connect to it. The label "not connected" is displayed belowe its name. I have an impression that the label "blinks" for a second and change to "connected" but then, immediatel change again to "not connected"
I have tried another application ("decathlon coach") witch works in similar way, and I have the same issue - the HR monitor is discovered, but it is not possible to connect to it.
I found very old post from the year 2017 how to downgrade the firmware but the method does not work now. Even though I switch to advanced mode on btu.bose.com I am still able to choose only current version of firmware (i.e. 3.0.3). There are error logs though, but not sure what they mean:

(and so on)
