Bluetooth Medic does not seem to help for Android Beacon Library
For some reason the monitoring doesn't seem to work well on my device. That's a Pixel 2 with Android O. Sometimes it works. Sometimes it doesn't. It seems really random. I've been waiting for much longer than 15 minutes - hours and it would still not detect anything. I'm using the RegionBootstrap for background monitoring.
Maybe the below is the reason for it not working? I don't have any other apps using BT that I know of running in the background.

I also added the Bluetooth Medic but it doesn't seem to be doing anything. It was running in parallel here. Debug filtered on 'medic':

So what exactly is happening here? I can post code later, but the post is already hitting the limit and maybe the logs might already give an idea.
Thank you!

I also just got this:

The log lines like below indicate that the Android bluetooth stack has exhausted the ability of new apps to start bluetooth scans for beacons:
03-13 20:34:48.112 32272-32311/? E/bt_stack: [ERROR:gatt_api.cc(1032)] can't Register GATT client, MAX client reached: 32
This might mean that 32 apps on the phone have already used all the bluetooth clients, but more likely it is caused by an OS-level bug that has exhausted all the client slots prematurely, potentially by leaving some orphaned.
This is one of the problems that the Android Beacon Library's Bluetooth Medic is designed to be able to detect and fix by cycling power to bluetooth, which releases all the client slots. In order to do this, you must configure the medic to cycle power on failures. Based on the logs shown, it does not appear this is happening, which may mean the medic is not configured to do so.
You can configure the BluetoothMedic to cycle power to attempt recovery like this:
BluetoothMedic medic = BluetoothMedic.getInstance();
medic.enablePowerCycleOnFailures(context);
medic.enablePeriodicTests(context, BluetoothMedic.SCAN_TEST |
BluetoothMedic.TRANSMIT_TEST);
