The DWM1001 antenna is optimised for channel 5, but it can also work on other channels…
The on-board FW that comes with DWM1001 only supports the 6.81 data rate and 64 PRF … this is the configuration used in DRTLS.
However users can erase the supplied FW and download own FW into the Nordic and configure the DW1000 to any other configuration they wish/DW1000 supports.
