What hardware are you using? The fact that it works out of the box on another distro sounds like usable drivers for your bluetooth dongle are not bundled in vanilla Ubuntu/Debian (either no drivers at all, or a version which doesnāt work properly)
This is a bit of a newbie question, but probably someone else is also interested in the answer. So, what kind of changes would be required to make the Pi just collect data and send it to an InfluxDB database which is located on a different computer on the same LAN? Iād like to do this to avoid the possible problems with SD cards wearing out and I have a desktop computer already running 24/7.
Hello Scrin,
Sorry for so late reply. Yes, you were right, it was an driver issue. My BT card is Intel AC9260 and turns out to be a bug in the package linux-firmware. The trick was that the BT was working, but not BLE 
Especially server distros are using older packages and to apply the new firmware the computer must be shut down, restart was not enoughā¦
Thank you so much for pointing me in the right direction, you have saved a few hours of my life
Hi all. I just found this cool looking ready-made image. However, Iām not able to login 
Could someone post the username:password combos for ssh and Grafana?
Using this image: ruuvicollector_2020-01-30.minimal.img.zip on a rpi3b+.
At least admin:admin does not work for Grafana, I guess it should? Weird.
Thanks!
Hello,
https://blog.ruuvi.com/rpi-gateway-6e4a5b676510 has details on the setup, default password on Grafana is admin/ruuviberry
Hi otso, thank you, now I got in 
I managed to create dashboard and queries, but all the graphs say āData points outside time rangeā. I then checked time/date, and they were really off. Ran raspi-config and set time zone accordingly, but it didnāt help at all. So, for same reason the rpi time and date are wrong and also the dns seems not to work at all, e.g. apt-get update does not work for starters. Iāve got some experience with piās and generally had no problems ever with the network/date/time. I really donāt understand why this installation is not willing to access internet at all. I can access the rpi with putty just fine ans ifconfig shows all is ok.
Is this a known feature, or something else?
Sorry, must be a stupid question
Hello,
Sounds a bit strange, as my Pis work just fine on the internet. Are you using wired Ethernet connection or WiFi configured through the RPi hotspot?
Its connected with ethernet, which works with another sd card (and version of Raspbian) just fine. Weird.
Itās probably this issue: https://github.com/jasbur/RaspiWiFi/issues/65
Iām traveling until 10th of February so I canāt check the fix, but please let me know if you try the fix in that issue and if it works.
The root problem is that RaspiWiFi redirects DNS queries to itself while hotspot is active if I understood correctly.
Worked straight away. Thank you soo much otso

Could anyone help me? I have Raspberry Pi 4 and I have installed Grafana, InfluxDB, Telegraf, Chronograf, Kapacitor and ruuvicollector. I am using latest releases. My wifi is not working properly after starting ruuvicollector.service.
- What do you mean āproperlyā? Intermittent connectivity? No connectivity?
- Was it working before installing Grafana and TICK stack?
- Have you examined /etc/wpa_supplicant/wpa_supplicant.conf? Is the modification date what you expect?
- Are there any messages in /var/log that are be related?
- Have you physically moved the Pi ? Can you move it closer to your router.
- Internet download speed is dropping to 0.01Mbps. Without the service running itās more like 40Mbps.
- I am not sure. I can do OS reinstall and install ruuvicollector first.
- wpa_supplicant.conf includes only my Wifi properties and they are correct.
- What should I be looking for? I didnāt see anything related to ruuvicollector.
- Pi has been at the same place all time.
Is Java 11 good for ruuvicollector? I saw some guides and they were installing Java 8.
I really appreciate the help.
Yes. Java 8 is the minimum required version (which was also the latest LTS version at the time RuuviCollector was initially developed). Java 11 will work equally well, and 11 is actually the version Iām using on my own setup at the moment. Though I use a RPi3 as I donāt have a RPi4 yet, but that shouldnāt matter for the collector.
1c) How are you timing download speed?
2c) No need to reinstall (yet)
6) sudo systemctl stop grafana # and do speed test
7) sudo systemctl stop ruuvicollector # and do speed test
8) sudo systemctl stop influxdb # and do speed test
9) Use top to look for unexpected processes and memory and swap usage.
10) How are you connected to pi HDMI monitor/USB keyboard/mouse or ssh?
I have tried to setup everything manually since I donāt have a Pi3 available. I have Influxdb, Grafana and Ruuvi collector running. I can see data in Influxdb so up to that point everything is working.
I can login to Grafana but how do I create the dashboard towards Influxdb so that I can see the data?
First you need to add the InfluxDB instance as a Datasource in Grafana, after that you can start creating dashboards and adding panels to them that use the datasource you added.
If you set the datasource as default when adding it, new panels will automatically use it by default. If you already created some panels on a dashboard youād like to use, you can change the datasource from the panel editor if it doesnāt get set automatically.
I added InfluxDB as default, created a dashboard and added a panel but I get āExpected response data to be array, got undefinedā
It is working now. I was using the incorrect port in the data sources settings.
