Dear Sir/Madam,
I hope this email finds you well. I have question when reading the data sent from sensor through UART. The data is in TLV format, and is shown below
Data:
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

Since i want to check if static object has been detected and the information of it. Therefore i am looking at type 10 of the tlv. and below data is the part that contain type 10 data and is in bold, 0a00000028000000000000000c92e7bcf263853ec0e3dbbc04e73c3e98fdd53f0bc4b23ff0e7703ddc9a763e00000000, and the data is also shown below with comment for better understanding,
0a000000 (tlv type)
28000000 (length/num of bytes)
00000000 (Target ID)
0c92e7bc (Pos X [m])
f263853e (Pos Y [m])
c0e3dbbc (vel X [m/s])
04e73c3e (vel Y [m/s])
98fdd53f (acc X)
0bc4b23f (Acc Y)
f0e7703d (Pos Z)
dc9a763e (vel Z)
00000000 (acc Z)
I would like to ask the following questions:
how to read the data in meters? Take the Pos X as example, is it giving the position of the target? How can I know the position of the sensors?
Are the data in bytes and is read like bce7920c for posX in hex if the original data is 0c92e7bc? But It will be so big if converted to the meters, and how can i find the distance beween the sensors and target?
Thank you in advance for your help. I look forward to hearing back from you soon.
Best regards,
Kevin
