According to the information I referred to earlier, there are two ways for MATLAB to call PlutoSDR. One is based on M language, and the time interval between reading the buffer of the device will lead to the loss of some data. The other is based on Simulink, and the transfer rate is relatively low, but data will not be lost. I tryed to use USRP to send data, and PlutoSDR to receive data by Simulink. However, the result seems to show that the data will also be lost. So is there any way to make plutoSDR not missing data during transmission?
