These commands are applicable to Raspberry 4 using Supervised installation, it is how I made it worked in my system.
Where did you work the second command and what was the output?
If hci0 is found, all is good, that is your internal BT. 
The thing with the scanning is: only a few devices are available as of yet, but more will come. Right now, these are:
This release adds five integrations built on this: SensorPush, Govee, INKBIRD, Moat, and Xiaomi BLE. The latter also provides support for the reasonably popular Mi Flora plant sensors.
So for now, if you don’t have any of the above named devices, it will simple not find anything. End of story. So if you want anything else, eg. some fancy BT sensor, it will not be discovered or work, yet. What is coming, I honestly don’t know.

It might be correct in some cases, but not for me. Even though i was able to see adapter in Bluetooth integration configuration, it was throwing errors as adapter is not ready. So seeing the adapter is not enough.
That’s strange, but good to know! 
I always thought, if it is up and running (read: you can see it), that would be enough.
I intentionally disabled the built-in BT, so i can’t say for my system, because I had to many interferences with the Zigbee dongle I’m using.
BLE monitor should support all BLE adapters, not particular ones. If your Bluetooth is working ok, so should BLE monitor. But the sensor should be one of the ones inthe supported devices list.
I used the commands you provided in SSH.
But the answer from Patrick explained it all, I thought enabling Bluetooth would show all my tablets, phones and multimedia Bluetooth able devices in HA, by which i could integrate them in the dash. It seems it is too early for that.
Thank you all.
I was forced to buy a USB dongle.
Only in this way am I able to activate the tracker!

Can you share which one you bought and how satisfied you are?
I was thinking about the ASUS USB-BT500
Bought a ASUS BT500 today, seems to be recognized as hci0, but so far nothing is detected. Even not my 3 Xiaomi temp/humidity sensors. Don’t know what I am doing wrong.
If you run HA on an Rpi that has built-in Bluetooth, then I think that hci0 is the native one and did not find the Asus BT500.
I don’t have an external Bluetooth adapter yet, but I still have a choice in the hci0 settings
Tried restarting HA ?
Hmmm well if I remove the BT500, and try to install Bluetooth I get an error, that it can’t be started. I am using an Intel NUC NUC5CPYB btw. But as far as I know, I have disable BT in the BIOS. Have to check that…
EDIT, just checked, BT is disabled in BIOS, so it must be the BT500
Probably yes. I don’t have a NUC, so I can’t give much advice on how to fix the problem
I just had this same issue and a restart did not resolve. O/S bluetooth tools didn’t seem to work properly either. I did a power cycle and everything came up properly.
I also have the BT500 configured as hci0 and have the same results as you. I am running HA Docker on a PC as well.

So is there still no possibility to use the raspberry pi 4 built in bluetooth with the bluetooth integration?
I can confirm TP-link does not work for me with rPi, keeps restarting. Works however fine on my Win PC.
Also perplexed as to my my Raspberry Pi Bluetooth isn’t working out of the box.
Wd love if each section of Home Assistant documentation came with a box of basics for newbs.
Something simple to stop all of us spending hours trying to get something to work that simply won’t.
Also - if the SOLUTION appeared at the top - wow.
Dies any ơn find a Solution for using Bluetooth ( bọth internal ớt usb dongle )?
In my Rasp 4, I see hci0 but can not scan/detect any device!
Best thanks
Same here, tried BT400, 500 and DG45 but nothing works.
Did you fix it? Using a mini PC Nipogi
