Hi all, I have a C program that uses SoapySDR that works for a LimeSDR but I'm having troubles with a B210.
I'm simply receiving as many samples as possible by packets of 680 samples, in mono channel, at 56MS/s. Soon after starting the program, I only receive 260 samples instead of 680. I close the device through SoapySDR and retry again, but then there's straight an error. Here are the logs I see: [INFO] [UHD] Win32; Microsoft Visual C++ version 14.0; Boost_106300; UHD_3.11.0.1-37-g2c9087d1 [INFO] [B200] Loading firmware image: C:\Program Files\PothosSDR\lib\uhd\images\usrp_b200_fw.hex...

Any idea what might be going wrong? Also is there a programmatic way to reset somehow the board, to avoid having to physically unplug then replug it? Thanks.
