Well keep in mind, the signal transmitted by the SDR comes from samples sent to it by the PC, so there's some delay there, and then on the receive side...

First off, not sure what you mean by "Pluto sdr but that does not have any synchronization mechanisms" because the Phaser is just a Pluto + Pi + phased array...

Oh wow, didn't realize it wasn't supported in the stock Pluto's HDL, weird considering this page is Pluto specific and mentions TDD https://wiki.analog.com/university/tools/pluto/hacking/power_amp. How long ago did you ask? There's...

Also tagging @jonkraft in case he sees this. Could be a nice section for PySDR, to explain the TDD engine.

Oh ok, so yeah it is supported with the latest code, I think you'll just have to spend time diving deeper into Jon's Python example here https://github.com/jonkraft/PhaserRadarLabs/blob/main/FMCW_RADAR_Waterfall_ChirpSync.py because it's as...

You can send 0+0j's to the transmitter to effectively turn it off, and as far as receiving, you can always toss out buffers if you don't care to process them,...

Pretty sure those 2 warnings don't have anything to do with why it's not working. But I can really only help with you getting it working in Python (not GR),...

Which function are you talking about? The TDD stuff is implemented here and it's mostly just setting fields https://github.com/analogdevicesinc/pyadi-iio/blob/main/adi/tddn.py A lot happens in the my_sdr.rx() call which is implemented here...

Not sure, you'll have to ask on the ADI support page I linked to, that way their response can be archived and easily found by the next person who comes...

Oh nice find!!! Any interest in adding it to a new section at the end of the USRP chapter? If not I can, might take a few weeks to get...
