No connection: Compatible with Board DWS1000 (Arduino Uno)?

[janknspde]

• Arduino IDE version or Toolchain: 1.8.19
• dw1000 Library version: 0.9.0
• Arduino device: Arduino UNO
• Used adapter board: DWS1000 https://www.mouser.de/datasheet/2/412/DWS1000_Product_Brief_V1_0-1878682.pdf

I have two Arduino UNOs with the shield DWS1000 mounted.
On one I run DW1000Ranging_ANCHOR, on the other DW1000Ranging_TAG, both from the examples.

The boards never recognize each other.

The terminal of the TAG is just forever:

device address: 7D:00:22:EA:82:60:3B:9C
### TAG ###

I've also tried BasicSender/BasicReceiver without success.

The shield is connected, without the shield the BasicConnectivityTest prints:

Device ID: 00 - model: 0, version: 0, revision: 0
Unique ID: 00:00:00:00:00:00:00:00
Network ID & Device Address: PAN: 00, Short Address: 00
Device mode: Data rate: 6800 kb/s, PRF: 16 MHz, Preamble: 128 symbols (code #4), Channel: #5

With the shield mounted, the output is:

Device ID: DECA - model: 1, version: 3, revision: 0
Unique ID: FF:FF:FF:FF:00:00:00:00
Network ID & Device Address: PAN: 0A, Short Address: 05
Device mode: Data rate: 6800 kb/s, PRF: 16 MHz, Preamble: 128 symbols (code #4), Channel: #5

The example code sets the pins RST to 9, IRQ to 2 and SPI to SS (which is 10 on the Arduino UNO).
I think for the DWS1000 shield it has to be RST to 7, IRQ to 8 and SS to 10.
But I don't see any effect after changing the pins for both boards.

My problem is similar to:

• https://forum.qorvo.com/t/arduino-uno-and-dws1000-module-communication-between-two-setups-problem/11392

But none of these are solved.

I'm very thankful for every hint and idea.
Thank you!
