Hi
Just loaded the latest ruuvicollector from jan-2020 installed on my Raspi 3 and all worked fine.
Then I made apt update and apt upgrade coomands and the updates of data stopped updating to influx / grafana.
I have checked the bluetooth connection to tagās with bluetoothctl scan command and can see that they are sending data. Using hcidump -t -x ā¦ doesnāt show any data.
So donāt upgrade your Raspi linux ā¦ before the issue is found 
This might have relation to Ruuvicollector stops Collecting data topic, but different reason.
If hcidump has been updated, you will need to repeat the commands:
sudo setcap ācap_net_raw,cap_net_admin+eipā which hcitool
sudo setcap ācap_net_raw,cap_net_admin+eipā which hcidump
Thanks, but not the reason. Found out that the ruuvi-collector doesnāt start on boot. If I start it manually all works OK. So the update spoils the āautostartā of the java. Where and how it is done?
The automatic boot is done via systemd, details are at https://blog.ruuvi.com/rpi-gateway-6e4a5b676510?source=collection_home---2------12----------------------- under āFinishing touchesā
Hi Otso and thanks
I have done that and the service is active but doesnāt update the base.
If I run it from terminal as java program it updates the database. But not as service. Service status says active and all seems to be OKā¦ The service script is the original and same as you referred to.

Found the difference when I run from terminal I use sudo. The service dosnātā¦
Linux SE is the reason and something changed on the updateā¦ What, I donāt know yet.

NOTE the hcidump in service has started when I started the APP from terminal as sudoā¦ that seems to be the issue that service doesnāt have rights to run under the service?
You need to re-run these two commands:
sudo setcap 'cap_net_raw,cap_net_admin+eip' `which hcitool`
sudo setcap 'cap_net_raw,cap_net_admin+eip' `which hcidump`
after hcitool and/or hcidump have changed (ie. updated) to re-add the required capabilities for running them as a regular user (including services)
OK thanks, now it works. I must have made a typo earlier as the same commands did not have any efect.
Case closed, I know now what to do in future updates.
Actually I found the issue here. The hyphens were missing from which hcitool and which hcidump
