was running a matlab simulation for "Detect Human Presence Using Wireless Sensing with Deep Learning"
But i am getting this message(as shown below) again and again and simulation is not moving further. Please help me how to fix this issue.

Hi Subhra,
I understand that you want to run the “Detect Human Presence Using Wireless Sensing with Deep Learning” MATLAB example but encountering an issue. By default, it uses pre-recorded data provided with the example. However, it also offers the option to collect new data using a Software Defined Radio (SDR) device for training the Convolutional Neural Network (CNN) architecture.
The message "SDR object configuration is complete! Run steps 1 and 2 to capture data" appears because the rxsim.UseSDR option is checked in the example which indicates that the SDR object has been configured and is ready to record ‘presence’ and ‘non-presence’ data, as detailed in the later sections of the code.
To use the pre-recorded data provided with MATLAB, uncheck the rxsim.UseSDR option and rerun the program. The example should then execute successfully.
For more detailed information, please refer to the MATLAB documentation at the following link: https://www.mathworks.com/help/releases/r2024b/wlan/ug/detect-human-presence-using-wireless-sensing-with-deep-learning.html

Dear Abhishek
I would like to run the example using SDR. My objective is to use USRP SDR B210 to confirm the presence of humans in real time. Could you please let me know if this can be done with the current example “Detect Human Presence Using Wireless Sensing with Deep Learning” ?
If it is possible, please provide steps and which are the boxes i should check/un-check.
Thanks and Regards

Hi Subhra,
Please find below the step-by-step process to run the example “Detect Human Presence Using Wireless Sensing with Deep Learning” in real-time using USRP SDR B210:
“SDR object configuration is complete! Run steps 1 and 2 to capture data”.
  • Close the message box to proceed further.
  • To capture the “no-presence” data using SDR, click on “create no-presence data” under step 1 of “System Description”.
  • Similarly, capture “presence” data using SDR under step 2.
  • Once, both the data are captured, create and train CNN using step 3.
  • To evaluate the performance of the CNN in real-time, click “evaluate performance” under step 4.
For more information, I would suggest going through the explanation given in the example. Hope it helps!
