I use 2 DW3000 chip
[scenario 1] Fluctuated measured result.
→ DWM3000EVB(DW3110) with nRF52840-DK setup as tag.
- No change any other values.
→ QM33120WDK2.0 with nRF52840-DK setup as anchor.
- Use PDoA mode 1 or mode 3.
In this scenario, the whole setup is expected to run under PDoA and we could select mode1 or mode3 @anchor.
From the section 4.2 of DW3000 Data Sheet, it tells the differences between mode1 and mode3. Mode 3 shold have higher accuracy than mode1.
But from the measurement result, it seems PDoA is not activated in scenario 1.(I am not sure about this)
All the setup is from EVB board even the antennas, but the result I I got is large drift in a rage from 0~100. The whole setup did not move.
Could anyone have any suggestions about this?
