Failed to open device : Insufficient permissions

[andrew77]

As I update the software, through
apt-get install bladerf
and the libraries I got this problem:
and@and-HP-250-G4-Notebook-PC:~$ bladeRF-cli -i
Failed to open device (first available): Insufficient permissions for the requested operation

Previous installation of libbladerf, fx3 and libusb (1.0.17) that didn't happen
how can I get it to work without "sudo"?

Thanks

I did it:

# Nuand bladeRF
ATTR{idVendor}=="2cf0", ATTR{idProduct}=="5246", MODE="660", GROUP="plugdev"

# Nuand bladeRF, legacy VID/PID
ATTR{idVendor}=="1d50", ATTR{idProduct}=="6066", MODE="660", GROUP="plugdev"

# Cypress Bootloader
ATTR{idVendor}=="04b4", ATTR{idProduct}=="00f3", MODE="660", GROUP="plugdev"

and then
sudo udevadm control --reload-rules

after unplug the device is always the same;

thanks

[andrew77]

Well done, thanks jynik for the quick reply as well!

It works now!
I changed permission to the folder /usr/share/Nuand/bladeRF and files and now works !

Now I'm thinking of downgrading the fx3 to 1.9.1 because I realized that the new fw doesn't work with Yatebts

Bye
Andrea

[andrew77]

Right John

no fret,
I just updated because It was since 1 year I didn't update the fw of the board,
My purpose is also to make the board working with other software: openLTE, srsLTE, etc...
I would like also to work with the new gqrx (96 MHz bandwidth)

Bye
Andrea
