We are trying to compare the DWM3000 to the DWM1000 and would like to have similar transmitting power on both modules. We found the specifications for the DWM1000 in the DW1000 user Manuel (Section 7.2.31.1) and are now wondering if the same settings work for the DWM3000 (we could not find any documentation on that).
If so, would the equal settings give similar transmitting power on the DW3000 and the DW1000 or not?
After some testing it became clear that power control settings are not the same for the dw3000.
Hi
I suggest to look at the example code we have for the DW3000. It tells the recommended values in section 5.2.4 dwt_configuretxrf
The API is avalaible on our website.

Thank you for your answer. Unfortunately the API guide only gives a recommended value, but not any indication of what value should be chosen for having the highest possible power. I assumed it would be 0xFFFFFFFF(kind of experimentally confirmed), but after noticing that the connection between a DWM3000 and a DWM1000 is much worse than between two DWM1000 I’m no longer that sure.
Fallow up: Is it expected that DWM1000 and DWM3000 perform much worse in terms of range than a DWM1000 to DWM1000 setup? Or what else could influence this behavior besides the power setting?
I too am looking of code example of adjusting TX power. Datasheet mention a fine and course adjustment. The API mentions and example 19 TX Power Adjustment Example. But for the life of me, I can’t find any mentioned example code on Qorvo website.
Someone please advise whete to find example 19.
Hi @robogo ,
The example you mentioned is available in the XR6.0C release in Qorvo website:

Hello,
I am having exactly the same problem as you - it seems like our DW3000s simply do not output the same TX power as our DW1000s - and I am trying to fix that. I have set txcfg.power = 0xFFFFFFFF; dwt_configuretxrf(&txcfg); and I still get about a factor of approximately 20 lower TX power than our old DW1000s transmit at. The DW1000s apparently use some sort of ‘smart TX power management’, but that is not available on the DW3000s - the docs effectively say ‘just do it yourself’. I can’t figure out how. I am not in the USA, so my ‘regulatory limits’ are much higher, and I need more than a 10m max range between my DW3000 modules (with the modules arranged for an isotropic beam function in the horizontal plane).
I saw you issue - which is similar to ours - and was hoping that perhaps you found a solution that you could share?
Thanks!
