IWR1843: The matlab cannot open the serial port while the serial assistant receives the data normally

Hi team,

Here's an issue from the customer may need your help:

The customer is reproducing a AWR1843 heart beat respiration detection project. Currently, xwr18xx_ccsdebug.bin is flashed. When CCS enters emulation mode, the data sent by the radar can be read in the Serial Assistant, but after closing the Serial Assistant and turning on the matlab emulator, it is not possible to open the serial port and will report "invalid execution". The object must be connected to a serial port.

Figure 1 shows the initial Matlab upper computer, which opens the serial port normally and Figure 2 shows the upper computer with some algorithms that is not able to open the serial port properly (which works properly on other computers).

Could you help look into this case? Thanks.

Best Regards,

Cherry
