Hello again.
I’m opening this thread in hopes of gathering as much information as possible to externally synchronize a couple of DWM1001-DEV boards.
Most importantly, is it possible?
I’d really appreciate any feedback of people who have already successfully externally synchronized the specific boards or have even done it software-wise by building code on the existing DW1000 API examples or DW1001 examples.
Thank you all in advance.
Hi QnQ,
Are you referring to clock synchronization ?
If yes then there are two solutions to perform clock synchronization :
Over hardware : you need a sync pin on each board, and wire all the board to the same clock. I don’t think it can be easily done with the dwm1001.
Over software : the clock synchronization over UWB is possible and has been implemented by several users. It requires a good bit of software work. There is some literature about that, but basically, implementation is based on accurate time stamping of TX,RX in addition to the use of a Kalman filter.
Maybe take a look at the document below that could help you :
Thank you,
Regards
