After doing some looking on this forum I found some info that others may find helpful too:

DWM1001 Non-PANS questions (accuracy, factory calibrated antenna delay etc.)

Hi, Thanks for the questions and sorry for the delay. What is the network configuration used by PANS and compatible with the factory antenna calibration stored in the OTP? Is it the one shown in Table 1 of the DWM1001 System Overview document? Yes it is. Listed below. [image] This gave me the following value: 0x404C404C Is the factory calibrated antenna delay equal for both TX and RX? And in this case it seems to also be equal in PRF 64 and PRF 16 mode? ? The module is tested with MDE…

Particularly helpful from that: POLL_TX_TO_RESP_RX_DLY_UUS + Preamble_length + SFD + PHR + Payload_length < POLL_RX_TO_RESP_TX_DLY_UUS

That helped me understand the relationship between the TX and RX DLY values. Using that, I was able to reduce my DLY values and increase my range accuracy back to the expected ±10cm. Rather than increasing the TX DLY, I was able to increase the initiator RX timeout - this solved all my issues.
