Hello,

I have made the connection by reffaring the dw1000 datasheet and spi connections with Arduino is perfect .I tried connecting directly to Arduino(dw1000 pin to Arduino pi).also using level converter .since I am using code from GitHub which you mentioned previously.but still I am not getting responses from the module

If you’re not seeing anything and the software is known to work then the first thing to check would be power and ground connections.
Then check the SPI clock data and chip select connections.

If you are sure they are all good then look for signal integrity issues.
Do you have a bypass/decoupling cap on the power input to the module?
Do you have short and clean connections for the data and clock lines?
Can you run the SPI clock slower? If it is signal integrity then that may help.

After that I’m not sure how much more you can do without an oscilloscope to see what is going on.

Some times there no communication b/w the anchor and the tag.for example
Tag is sending BLINK message. It was received at the anchor. and then anchor is sending RANGE INIT message. But it was not received at the Tag .This process is repeating.So we are not able to get the distance value continuously in order to track a device.

and also one thing we noticed that some times the address was not set properly in Tag device. So what we need to do to get the distance value continuously. for details refer the attachment.

Still sounds like it could be signal integrity issues. What’s the wiring like? What’s the power supply like?

Hello,

Anchors and Tag is working properly and able to read distance.But if measured distance in arduino is 2 meters.physically it will be 1.2 meters on measurement using measurement tape.

is this level of accuracy will affect localization(using multi-alteration algorithm) of tag?
What is the maximum distance that module can detect(range of module)?
in my hardware setup modules can detect only within 8 meters.
