Hi,
I have the same problem. When the camera switches off (automatically or manually) I have to wake up the phone (not necessary to unlock) to reconnect bluetooth.
My phone is a Sony Xperia XZ1 compact.
I tested the same with a Samsung galaxy A3 and there automatic reconnection works just fine.
So it depends on what phone you have. You could be lucky...
I already sent this issue to the german ricoh support but they just told me they cannot reproduce the problem. Everything works fine. They tested "a Samsung" with Android 10 and a iPhone with iOS 14.5
I suggest that everyone that have the problem should write to the support. Maybe they re-think and test with some other phones too.
Thanks!
I did contact also Ricoh/Pentax support, no answer so far.
I went through every possible battery saving feature, turned them all off .. nothing helped.
I also tried Samsung A52.. was even worse. Got it to work once and after some time I could not reconnect at all. Had to start over with pairing etc.
It's a mess! It is probably in part problem on Android side as well .. but. .. these problems should really warn Pentax .. they have to keep GPS in their next K-1 and not to rely on this phone based solution. And no .. I not buying the large GPS unit that they sell .. that is not a solution for walking around with the camera.
