Hi Andy,
Thank you for taking the time and writing this helpful reply.
the default crystal trim value on the OTP is 0x10. I did change the crystal trim value in the register from 0x0A to 0x14 and checked if the reception on the tag side (dwm1000) is working but with no luck.
I don’t write the new value to the OTP since I only have 3.3V connected to the dw1000 but I update the register(0x2B:0E) using dwt_setxtaltrim(), so i’m not sure if it’s taking in consideration by the dw or not ?
I also received the tag new version with the dw1000 modules instead of the dwm1000 and guess what ? it worked right away !!! (with another dwm1000) ! same circuit, components…ect! doesn’t really make sense.
I’ll be testing with a spectrum analyzer and will keep u updated
