Hi all, I don't know if this is the right place to ask, if not feel free to forward the mail or point me in the right direction. If I look with btmon i see no Covid exposure notification beacons from android phones, i see these beacons from a iphone. When I check with a ESP32 with a monitor I see both beacons (from iPhone and Android). I using Raspberry Pi 4 with with all software updated. I updated bluez to last release (from 5.50 -> 5.54) with same results. Used software versions : Installed image : Raspberry Pi OS (32-bit) with desktop Release date : 2020-05-27 Bleuz version 5.50 and last release 5.54 (build from source) If needed I can recompile from source a new version. I tried to find source of a more up-to-date developer version then 5.54 but could not find this. So is there something I can do to enable to see Android Covid exposure notification ? Do I something wrong or is there a bug in the bluez stack? Background : I am making a 'CoronaCounter' app in python, I want to count the Covid exposure notification that I see. In python i use beacontools. I noticed I don't see any android beacons. More about this projcect you can find on https://github.com/zeno4ever/CoronaTeller Regards, Dave
