welle.io_2.4_Linux_x86_64.AppImage not working in opensuse Leap 15.4

[seuchato]

Hi I have a daily updated install of opensuse 15.4. I do have this sdr stick: Bus 001 Device 023: ID 0bda:2838 Realtek Semiconductor Corp. RTL2838 DVB-T It is the blue "nooelec NESDR Mini 2+ "820T2 SDR & DVB-T" stick. Using gqrx, it is recognised plots a waterfall spectrum and plays sound. I'd say it works. But I'd like DAB+ => enter welle.io:

I downloaded welle.io_2.4_Linux_x86_64.AppImage and started it. No burger menu, no scan option and off course no stations, see attached screenshot: How can this be fixed? greez chris

Assuming you are from a German speaking country (due to the screenshot), please use the expert settings and scan manually 5C (if you are from Germany) or 12C (Switzerland).

If you are from Austria, please note that the Bundesmux is not available in some regions. Therefore, check https://dabplus.at/

Anyway, please add the spectrum diagram and take a screenshot and post it here.

Furthermore, try manual gain settings or change the (very very cheap) RTL Stick.

The icons seem to be invisible in your case, so please use https://www.welle.io/ for an instruction.

Thanks, however I have not found a clue to start welle.io in expert mode. Maybe, you could point me to some reference? Meanwhile I built a rpm and started welle.io from it. Here is a screenshot: About the same as before, but now I got the prominent red message saying there is no device found, it uses standard device.

welle-cli seems to confirm at least a problem with invoking the rtl device. Here is what I get from: `welle-cli -c 12A

welle-cli unknown

InputFactory:Input device:auto

RTL_SDR: Open rtl-sdr

_RTLSDR: Found 1 devices. Uses the first working one

usb_claim_interface error -6

_RTLSDR: Opening rtl-sdr failed

SoapySDR: No usable SDR device found

Error: No valid device found use Null device instead.

OFDM-processor:restart

Wait for sync

^C ` Somehow the highlighted parts are contradicting?!

Here is additional info following up my previous post

(as code tags do not seem to work, I use ### to wrap code)

unplugged the stick and then:

restarted welle.io, now the red message is gone, same screenshot as on Nov 22: no burger menu, no stations, no option selectable. "welle-cli -c 12A" still prints "usb_claim_interface error -6 // RTL_SDR: Opening rtl-sdr failed"

So no progress

[seuchato]

Some success: copied "https://raw.githubusercontent.com/osmocom/rtl-sdr/master/rtl-sdr.rules" to /etc/udev/rules.d, unplugged the stick, did "udevadm control --reload-rules && udevadm trigger", plugged the stick back in, now I get this:

########################################### welle-cli -c 12A welle-cli unknown InputFactory:Input device:auto RTL_SDR: Open rtl-sdr RTL_SDR: Found 1 devices.

So, it seems there was a problem in the previous udev rules. However, the gui "welle.io" is still as per previous posts: No burger meno, no options selectable (apart from "favourites/all stations", Play and volume, which I forgot to mention in previous posts).

[andimik]

You will find the (invisible) icon (...) right of the volume icon.

There please use the expert settings and follow my hints above.

Or you use rtl_tcp on port 1234.

I am listening to DAB right now. The key was the rules file plus finding the menu to switch into expert mode. There is a button(?) and a menu not visible on my box: Expert settings: right of volume pictogram: Outmost left of text "welle.io" This one toggles station list.

Why are these two without any pictograms? The one on the right side should show ie. three vertically arranged dots, and the one on the left should show How do I get these pictograms where they should be? By the way, this is on both the app image and the rpm based install.

See #725 and #713

I am listening to DAB right now. The key was the rules file plus finding the menu to switch into expert mode. So big fat thanks Andimik. I am yet to apply the patch. I guess the current source tarball has that patch already. Any interest in getting my rpm here (provided, it works on other machines too)?

[seuchato]

Applied the patch, rebuilt the rpm installed with rpm -Uv, verified the new version is installed, but burger and three dot menu pictos still are not appearing. I develop apps under GT-designer myself. Will try to get it imported and see from there where it fails.

[seuchato]

Have it sorted out. Rpm installs and runs nicely. Thanks for your support. I repeat my offer to share the rpm here, if wanted.
