i am nandu working in tenet technetronic as an embedded engineer. Since am working in bladerf device in ubuntu 14.04 by following prescribed manual and wiki page given in Nuand/bladeRF wiki page during the installation process, there i had a problem while checking basic device operation.
By running the command "bladeRF-cli -i"
The error is:Failed to open device (first available): Insufficient permissions for the requested operation.
And also i tried the command "sudo bladeRF-cli -i"
The error is: Failed to open device (first available): Operation timed out.
Please find the below attached documents regarding to the problem i have faced and Please rectify the above issue.
Thanks & Regards

Re: issue regarding to the bladeRF intallation
What happens if you run with the "-v verbose" option?
Do you see any anomalies in dmesg when you plug in the bladeRF?

Re: issue regarding to the bladeRF intallation
hi, thanks for the reply,
i tried "-v verbose" it shows an error "-v: command not found" (img1).
Also i tried in other option that "bladeRF-cli -v verbose" than also it shows the same error
"Failed to open device (first available): Insufficient permissions for the requested operation" (img2).
Thanks & Regards

Re: issue regarding to the bladeRF intallation
Apologies if it wasn't clear. The "-v verbose" is an option to bladeRF-cli, so run either:
or, if you haven't given your user the appropriate permissions:
We recommend that you give your user permission to access the bladeRF device. You can do this by adding your user to the appropriate group. The group is specified when you build libbladeRF. The default group is "plugdev". More details here.
Code: Select all
bladeRF-cli -i -v verbose
Code: Select all
sudo bladeRF-cli -i -v verbose

Also note the permissions of the hosted*.rbf file ... you'll want to make sure your user has read access to that file.

Re: issue regarding to the bladeRF intallation
It's telling you the problem in that error message. There's a permissions error of some kind (though I'd have expected sudo to have gotten around that).
- What does the command "ls -lha /usr/share/Nuand/bladeRF" show?
- What does the command "groups" show?
- Have you tried logging out and logging back in or restarting to make any group changes effective?
- What if you download the latest hostedx115.rbf from our website and try to use that? (run "bladeRF-cli -l /path/to/hostedx115.rbf -i -v verbose")
