Hi Saharat,
What exactly are you trying to do? Did you port one of the examples to the Arduino UNO?
It looks like you are using the examples in the arduino-dw1000 project, You will probably have to change the pin configuration for this to work with a DWS1000 on an Arduino. This software was designed for other (undocumented?), is not supported by Decawave and currently not in active development by the author.
Note that due to the relatively slow processing power of the Arduino UNO using it for UWB RTLS solutions is not ideal. See APS019 Issues to consider when porting the DecaWave
DecaRanging source code to an 8-bit MCU. For this reason, Decawave does not support the Arduino Uno as development platform. It’s good enough for simple demos, but simply doesn’t allow to use the full capabilities of the DW1000.
