Hi all

I am using DWM1000 for indoor navigation. I used to keep the tag in my pocket and the data are shared via bluetooth from tag .Some time i am not getting exact range report from tag . It is giving zero values. Is there any register configuration in DWM1000 to optimize NLOS issues

Now i am using the configuration mentioned below

                     2              // channel
                    DWT_PRF_16M,    // prf
                    DWT_BR_6M8,    // datarate
                    4,             // preambleCode
                    DWT_PLEN_128,   // preambleLength
                    DWT_PAC8,       // pacSize
                    0,       // non-standard SFD
                    (129 + 8 - 8) //SFD timeout

Hi dhanraj,

I would recommend you to look at the application note below that gives a lot of indication about how to handle non los issues :

Let me know if you have any other questions,
Thank you,
Best regards

Dear Yves,

Do you know if there is an updated document for DWM1001 module? or it is also applicable?


Hi David,

The documents above à apply to any product using decawave UWB technology (dw1000) , including the DWM1001.

Keep in mind that the DWM1001 is designed for channel 5, and that the rf configuration of PANS cannot be modified.
