How do I get CIR data from DWM3000?

Hello, I own 2 DWS3000 shields. How do I go about extracting the raw Channel Impulse Response values, I am currently running the Single Sided Two way ranging with STS initiatior/responder examples. I am new to the devices, so any help will be greatly appreciated!

Much thanks!

It is available by reading from register address 0x15, as with the DW1000 the first few bytes out need to be discarded. The data packing isn’t standard so you’ll need to convert it into more standard data types before doing anything else.
Section 8.2.19 of the DW3000 user manual gives the details on what the structure is.

Hi Andy,

Thank you for the reply, I’m looking into the user manual!
