have a look at this maybe:

by Juerd

sounds like lots of fun and lots of possibilities but haven't test it myself.

edit:

or modify Net::Bluetooth's get_remote_devices() to also report RSSI

I have been playin with Juerd's script a bit already, but it suffers the same drawbacks as most other readily available solutions: it does not "see" my device. hcitool is listed as deprecated. It does not show my phone when scanning. bluetoothctl is working very well, but it needs root/sudo to connect to the phone to get the rssi data.

When I get some time, I want to investigate an XS module that uses libbluetooth (just like Net::Bluetooth).

Maybe one needs root access to enquire bluetooth device directly but this information usually is held/collected by the system in the same way as a wifi manager collects AND displays the signal strength of each neighbouring network. So a possibility would be to ask the window manager or whatever other manager instead of accessing system directly.

Here is an example for gnome: https://wiki.gnome.org/Projects/Vala/DBusClientSamples If I understood correctly you need to detect mobile's presence from your opensuse desktop, so if you are using gnome then ask gnome for it.
