Thank you very much for your valuable answer.
I am using Arduino. Here is the library for DWM1000: arduino-dw1000/DW1000Ranging_TAG.ino at master · thotro/arduino-dw1000 · GitHub
You can see that in the loop it has: DW1000Ranging.loop();
Is there a way to turn it off when I’m not using it? So that it consumes 3.5mA. It occurs to me to place a conditional in the loop to disable the DW1000Ranging.loop(); when I press the button. What do you think?
