Re: Why I got 32'hCDCDCDCD like this using signaltap?

Let's try to track this in one spot. Because you made a GitHub issue, let's start there.

Re: xb300

The XB-300 is an amplifier board. There's a PA for transmit, and an LNA for receive. The ADC on the XB-300 just converts the PA's power detect voltage to a digital value that can be interpreted by the FPGA/host.

Re: GSM and amplifiers

Be aware that the bladeRF should not be exposed to signals greater than +23 dBm as this will damage the RF front end. The ADC saturates at a much lower input power -- around -13 dBm. Your issue with the amplifier could be that the signals are too strong and therefore are clipping either at the hands...

Re: Failed to receive NIOS II response: Operation timed out

It's probably related to the USB pass through to the VM guest OS and then trying to access the bladeRF from the host OS.

Re: BladeRF on Windows Subsystem for Linux (WSL)

We have not tested this functionality. My initial guess is that this is a limitation with WSL. I know they had some trouble getting USB drive support working initially. Not sure if other types of devices would need specific fixes as well. I'm curious -- does "lsusb" work and/or detect the bladeRF? I...

Re: Unabe to start YateBTS with bladeRF

Wonderful! glad you figured it out and shared the solution. Would you mind sharing the bladeRF version info so it will help others who may have a similar problem? You can do this by running the command:

Code: Select all

bladeRF-cli -e version

Re: 5.8GHz band

Nothing made by Nuand at the moment, sorry. You may be able to find a connectorized block up/down converter, but I'm not aware of any off the top of my head.

Re: Unabe to start YateBTS with bladeRF

What guide were you using to set this up? Evilsocket's guide uses libbladeRF version 0.16.2, so that might be a possible cause of this issue. Are you able to get more verbose output from Yate to determine the actual cause of this error?

Re: bladeRF being (USB) disconnected during FPGA firmware recovery

Glad you figured it out. I was going to suggest that this sounds like a power interruption issue to me -- either caused by the host, or the bladeRF itself. The latter being unlikely if it was working fine before the attempted firmware update.
