Re: Help with Transciever

Greetings, Yep, full-duplex operation is possible with the hardware and underlying library, and should (in theory) be possible with the Python bindings, although I haven't tried this yet. You'd want to alternate between sync_rx and sync_tx, keeping the TX buffers as full as possible and the RX buffe...

Re: Best way to test basic operation of BladeRFx40

Greetings! We have a walk-through of how to verify basic functionality at: https://github.com/Nuand/bladeRF/wiki/Getting-Started:-Verifying-Basic-Device-Operation My usual "smoke test" is to transmit /dev/urandom, which will produce a nice big blob around the center frequency. Something like this wi...

Re: bladeRF micro phase coherency

G'day, Maybe! We did plan for this during design, but as far as I know, it has not yet been attempted. From the looks of things, the FMCOMMS5 uses an ADF5355 to generate LO signals to be fed into RX_EXT_LO / TX_EXT_LO pins on the '9361s. We expose these traces on U74 (the expansion connector) on pin...

Re: Getting the A9 rolling in Windows

FYI: the issues with the "probe" command not working under Windows have been fixed in the latest libbladeRF. Also, the Windows installer now creates the proper mapping for the bootloader recovery mode VID/PID, so recovery can be done entirely with bladeRF-cli and without using zadig (hopefully), jus...

Re: FPGA Firmware 0.8.0

FYI: if you *do* use SPI flash autoloading of FPGA images, FX3 firmware 2.3.1 ensures that FPGA programming is complete before letting the host open the device. This means you don't have to watch for the lights: you can just plug it in and go, and libbladeRF will block until the load is complete. Al...

Re: FPGA Firmware 0.8.0

That was mine, back in the day. :) Continuous automated builds are on my to-do list, and there is progress! It's just slow, behind-the-scenes progress. BTW, if you want to give it a shot, the original buildbot source is at https://github.com/rtucker/bladeRF-buildbot ... see also https://github.com/r...
