Send current data at the time of sending

Hi, I have a sensor that updates readings every millisecond, how do I send the data in the .Send1ByteNumber parameter so that the current value at the time of transmission is received every half a second from this sensor so that everything is not transmitted in a row and clogs up the stream? Help build blocks. Because my data has been updated a long time ago, but the bluetooth on the arduino is still receiving old data. Even when the sensor transmission was completed, the arduino was still processing the data.

Set the clock in the application to e.g. 300ms. However, data from Arduino is sent every 500ms. Just send slower, receive faster.
