We are trying to start broadcasting on a stand-alone Ettus USRP X410 using an external trigger. However, we have not succeeded yet. We tried using the GPIO and some code snipplets we have found online but there was no working solution yet. Does anyone have a starting point how to set this up properly? We have no custom FPGA image. Let me know if any further information could be helpful (sorry quite a beginner for software defined radios)
