So, if I haven’t totally misunderstood, that’s something I’m able to do myself (maybe). Well, gonna fiddle aroud with my ubuntu anyway so might as well fiddle with bluetooth.
I don’t know what kind format is correct format for tag’s information but noticed this one in sudo btmon

At least it looks like it’s reasonable
And after that I found that same plen number from hcidump -X

Just quick note before heading to bed after fiddling around with bluetooth long enough. Very first time I tried to do something with Ruuvi tags I tried Bluewalker, I had no knowledge what-so-ever.
Anyway, just started ruuvi-collector service and started bluewalker to run in terminal and… I get data out from Ruuvi tags.
My friend was certain that Ubuntu 20.04 and bluetooth 5.0 wasn’t good combination but apparently I managed to do something for once.
Ps. happy new year pals.

Update after 6 months: something broke suddenly after shutdown and starting again my server.
Bluewalker is able to scan Ruuvi tags as it should be. Ruuvi Collector runs without problem.
Problem here, as far as I know, seems to be that hcidump doesn’t see data which Bluewalker sees.
If I stop Bluewalker and execute bluetoothctl and after that scan on and check hcidump, it shows data ( but won’t send it to InfluxDB ).
Permissions may get broken on update, this thread had similar problem and a solution: Bluetooth connectivity issues.
Let me know if it fixes your issue

It seems that it was just those capabilities was missing. I executed for hcidump and hcitools, after reverting some of my own fidlings, it started to work. If only I would have asked that earlier.
Anyway, thanks for the info, otso!
Old threat… same problem.
I have new installation Rpi… I got data from RuuviCollector first few boots after setting up the system → Ruuvicollector → InfluxBD → Grafana. Then started problems.
At the moment I get warning Failed to start lescan.service: Transaction order is cyclic. See system logs for details. See system logs and 'systemctl status lescan.service' for details.

hcitool lescan gives BT devices MAC adresses nearby.
hcidump --raw gives only:
HCI sniffer - Bluetooth packet analyzer ver 5.55
device: hci0 snap_len: 1500 filter: 0xffffffff
What I should do?
