Can't turn on Bluetooth on my Banje.js 2. Software or hardware problem?

[Ju1230]

Got this problem for almost a year now.
When switching on Bluetooth in the Settings following the instructions my device is not visible/ I cant connect.
Reboot, resetting Setting, factory reset, using different Browser/ PC/ Android all doesnt work.
In the past when trying to connect iw would work like 1 out od 10 or 20 trys but now it doesn't work at all...
I'm pretty sure its the watch thats not working but im unsure if its a software or an hardware issue. When making the watch connectable in Settings the little bluetooth "B" icon does not light up blue.
Got my watch in fall of 2023. I guess the system version (?) is "2b0e"
Thanks in advance an love the watch <3

Sounds like maybe a hardware issue, do you see the problem after doing a factory reset? (from the settings menu)
