I connected it to the PC and nothing changed, D20 is still blinking fast, no other led is operating, and once in several seconds some of the led blinks several times.
It looks like it is trying to start with no great success.
I have 3 anchors which operate fine (I am afraid to touch them…) and 5 which has the D20 phenomena.
Ok that’s a bit strange, never happened to me. Do you have an android device on which you could install the Decawave DRTLS manager (available on the playstore) and check if the DWM1001 board are detected over bluetooth ?
Well you could download the virtual machine from our website and it has a fully working development environment for DWM1001. It comes with a makefile which has a recover step, charging the factory firmware on the board.
Ok good to know for the stuck reset button, I haven’t experienced that myself but will know for next time.
The uart has to be configured as 115200, 8 bit data,one bit stop, no parity, no flow control. I would expect a lot of disruption of the data on the uart, which command are you using ? From an anchor or a tag ?
It is not possible to get the position from an anchor, you need to read it out of a tag or a listener (effectively a passive tag).
So i would recommend you to setup a passive tag, read it’s output over uart and you will get the position data from the tag.
