Start
continuous
ranging
After the radar receives the continuous data request, it will immediately respond to your application with a continuous
mode confirmation instruction, indicating that the radar has received the instruction from your client and enters the
continuous ranging mode. At this time, the radar responds to the application client's confirmation instruction for:
Header
Data
content
Confirm
continuous
ranging
After that, we will continue to reply to the data packets that have been packaged in the previous cycle, in continuous request mode.
There is no delay in the data packet you receive. After the radar packs the data into the buffer, it immediately sends it to the
application client as shown in the following figure:

Continuously send data packets 3#

Continuously send data packets 1#
For the format of each data frame, please refer to STEP14 (Request Data (Single)). If you need the radar to stop the continuous
ranging mode, you need to send the following command to the radar:
Data
content
Header
while (scandata[numberOfBytesRead—1] != 0x03);//Because the multi-segment PSH=1 is used for
segment transmission, it must detect the trailer (ETX, 03h) before it is considered that the
reception is complete. This part of the content is complete for the data packet Reception is
very important
