I am using DW3000 with NRF52833. I have a problem with reading RX timestamps in double buffer mode. I’m using decawave API to communicate with the chip. I’m getting completely wrong values while reading RX timestamp like the following.
(unsigned 40 bits)
674709128635
1072876312206
674709128635
1072876312206

What would be the reason behind these wrong values?
If anyone has a solution, please let me know.
Note:- Timestamps are perfect in single-buffered mode.
