Aranet4 pairing tips or tricks

[surfingreg]

Hi,
I have an Aranet4 that works just fine with the iOS app. However, per step 2 of your readme, I'd like to pair it either of my my Linux or Mac machines then run this app. I can't for the life of me get the aranet to enter pairing mode. It doesn't show up at all on the Macos bluetooth list. On Ubuntu it shows up but never pairs when I double click it from the bt list. I've tried all the Linux command line variations of the following commands. I usually get org.bluez.Error.AuthenticationFailed or AuthenticationCanceled. Never do I get a pin code on the Aranet nor a prompt asking for the pin code. I've removed it from the app, turned off bluetooth on both possible phones it was ever used on. And I've tried turning off the dip switch for bluetooth, putting the batteries back in, then taking them out, turning the switch back on and putting the batteries back in. How do I factory reset the Aranet4? What else can I try?

Thanks in advance for any ideas!

aranetctl --scan (how i found the MAC in the first place; connect crashes without being paired first so...)

systemctl restart bluetooth
bluetoothctl disconnect 60:C0:BF:48:BD:41
bluetoothctl untrust 60:C0:BF:48:BD:41
bluetoothctl remove 60:C0:BF:48:BD:41
bluetoothctl scan on (ctrl-z)
bluetoothctl pair 60:C0:BF:48:BD:41

This is all I get back:
