advertise / reconnect to safe battery

[kpckpc]

To safe battery in my gadget, I wanted to change to advertising instead of a connection that has to be kept alive.
It seems that WebBLE did not implement advertising support yet.

So instead I tried to opt for a polling reconnect instead (shifting the battery burden to the phone instead). But this does not seem to work in WebBLE. I tried one of the examples from the Web Bluetooth examples.
https://googlechrome.github.io/samples/web-bluetooth/automatic-reconnect.html
On my PC and under android this works, even on the Iphone under the other app (B...F..) the example works, but not on WebBLE.

Edit: I just noticed another ticket, probably the same issue:
