GNU-Radio duplex
Posted: Thu Jun 18, 2015 5:29 am
Hello,
I simply tried to transmit a sine over osmocom receive it and calculate a fft.
TX and RX allone works well. Only sometimes the usb is gone away and I can not reach the bladerf until I have unpluged the USB cable and pluged in again.
TX and RX together do not work! The following failure appears:
FATAL: [bladeRF sink] Failed to open bladeRF device libusb:instance=0
After that I am not able to use the cli (GNU-Radio is closed before).
I have tryed on notebook and desktop booth results the same.
The device arguments for osmocom are: bladerf=0,xb200=custom
I try to send at 13.56Mhz.
Without the xb200 it works well! So the xb200 makes trouble on usb i think.
Is there a reason for this or I am doing something wrong?
I have found an old thread. It says I have to patch the xb200 manually to the osmocom, This is not mentioned in the wiki. Or does it mean the device arguments?
THX
