Examples

Stop Data Capture in the Background with Baseband Receiver

Create a baseband receiver object, specifying a radio setup configuration previously saved in the Radio Setup wizard.

bbrx = basebandReceiver("MyRadio")

bbrx = 
  basebandReceiver with properties:

               RadioGain: 10
         CenterFrequency: 2.4000e+09
              SampleRate: 250000000
                Antennas: "RF0:RX2"
    DroppedSamplesAction: "error"
         CaptureDataType: "int16"

Request 5 s of IQ data in the background and save it to a file in the basebandData folder called capture1.mat.

mkdir('basebandData');
[dataPath,~] = capture(bbrx,seconds(5),SaveLocation='basebandData/capture1.mat',Background=true);

Check if the capture is in progress.

isCapturing(bbrx)

ans = logical
   1

Stop the capture after 1s.

pause(1);
stopCapture(bbrx);

Check that the capture is no longer in progress.

isCapturing(bbrx)

ans = logical
   0

Check the status of the capture by using the isCapturing function before using the stopCapture function:

isCapturing(bbrx)

This function returns 1 (true) if a capture is in progress in the background.
