@Emil: hello Emil.. I am sorry for coming back with all my strange problems..
Now: In the app settings on my Android-phone sorrily I can't find a "Submit debug log"..

But: There seems to be a strange time-delay between changing something at the Buttons and the change taking effect or showing up:

• The one I wrote about yesterday misteriously disconnecting after some seconds now over night suddenly stays connected and works fine.. (Lights up green when pressed)
• The other one which worked yesterday I altered to Universal mode today to emulate a keyboard key.. - First it seemed to not accept the "store and disconnect"-action.. - It was not possible to connect it via Bluetooth to a laptop (..did not show up in the BT-list after pressing..).. - But after letting it alone for some hours it suddenly works as HID.. (blinking 2 times yellow when pressed)..

I would be happy to understand what is going on here..

Thank you for your patience
Best greetings
Jörn

@Emil : what I forgot to mention: sometimes after inserting the battery in the malfunctioning flic-button after pressing the button the LED stays dimly lit (yellow)..

@Emil : Thank you for the information about battery voltage levels.. - that is a valid point.. - I got better 2032s now: 3,1 V out of package.. - One of my flics works fine now.. - But the other one still acts strange: I put in a new battery. - flic's LED shows a short red blink. - If I then press the button, it connects to the telephone. - But after some seconds it disconnects and when I press the button, nothimg happens.. - ..after taking out and reinserting the battery it shows the same bahaviour.. -- maybe broken?
..strange.. - could possibly a reset be helpful?

@Emil Hello and thank you for your reply.. - I measured the batteries: one has 2,96 V, the other one 2,65 V.. - Both batteries were fresh out of the package.. - Strange: after some days of not working at all the one with the higher voltage battery now works after reinserting the battery..
I use the flic for triggering audio-cues during my magic-shows and I liked it very much for its reliability. - I would be very glad to regain this status..

hi* after changing the battery in two flic 2 buttons both show this strange behaviour: they connect and work but after a very short time (< 1min.) they disconnect and are shown as "standby"in the app and no light shows up in the button when pressed.. - removing and reinsering the battery results in the same behaviour again..
What can I do..
