Bitcraze Forums

this page says dwSetChannel(dwm, CHANNEL_2), does it mean that UWB channel 2 is available in the LPS node?
If so, is the bandwidth of channel2 3774 ~ 4243.2 MHz?

The nodes use the Decawave DWM1000 modules (https://www.decawave.com/product/dwm1000-module/) the best source for this type of information is their data sheets.

Thanks kristoffer.

First, I would like to use the DWM1000 node legally in Japan.
I have read the DWM1000 datasheet and it says ch2, 5 are available but, no bandwidth values were not written. In Japan, ch2 (3774 ~ 4243.2 MHz) is allowed by law among them.
So, I would like to know if the bandwidth of ch2 of DWM1000 is actually 3774 ~ 4243.2 MHz, if bitcraze has ever been to measure it.

We have not done any measurements, but I think (hope) you can find what you are looking for in the documentation.
The DWM1000 module is a small PCB with the DW1000 chip + antenna, so you should look for specs of the DW1000 (it is not obvious, sorry!)

I found the supported bandwidth for channel 2 on page 18
Thank you for taking your time.
