From what I read the timestamp on the Lime correspond to the FPGA counter in the RX part, and so it isn’t defined until you start to RX.
What does that mean for the TX part at the SoapySDR API level? To transmit something I have to pass a buffer as well as a timestamp. I guess it means the Lime will start streaming the buffer when that timestamp is reached. But then what happens if I never set the RX part?
Thanks for any pointers on how to use that TX API.
