BladeRFx40 get freezing after some days

Post by pablo » Mon Mar 19, 2018 2:14 am

Hi all,

I am running an experiment of long duration in the university of Vigo with the bladeRFx40 recording I/Q in KA band and then I process the files recorded with matlab. The problem is sometimes the bladeRF get freezing and stop recording (I am using SDR-RADIO Console). It is random sometimes stop recording after 15 days and others times in 5 days. My computer has good caracteristic I don't think is problem of the CPU or memory.

My guess is the usb does not provide enough power to the bladeRF. Could I increase the power using a usb-Y [1] or a powered hub [2] without danger?

Any other idea would be welcome. I would like to record continuously whole months.

Best regards,


[1] ... =usb+doble
[2] ... ds=hub+usb

Well that's not good! Do you receive specific error messages at all? Does it seem like the device is getting disconnected from the host, or does it actually hang? The USB controller could be an issue here. We have a list of known problematic controllers. There's a list of known good ones above it as well. Of course neither list is comprehensive.

If it is power-related, you're better off getting the recommended power adapter for the bladeRF. Those hubs and Y cables may not work too well and may even cause their own set of reliability / data issues.
