Very high DWM1001 current consumption in OFF+SLEEP mode

Wireless Connectivity Ultra-Wideband

Hi Epenciso,

apologies for the late response. I can confirm your observation is correct. It is a bug in PANS. Thanks for the feedback!

To summarize the issue:

  1. Tag in low power mode with BLE enabled and is in range with the network - power management works correctly and the average current is ~15uA (with stationary detection enabled).
  2. Tag in low power mode with BLE enabled and is out of the network (it seeks for the network) - the average power consumption would be > 425 uA - this is a bug in PANS.

Solution options:

  1. Disable completely BLE on the Tags.
  2. In case BLE is necessary - then disable BLE when the node is out of the network and enable it again when being back.
  3. We have not investigated yet the exact cause of the issue but we can do some bugfix / customization if you need an update soon. Please contact us via https://www.leapslabs.com/ in that case.

Thanks,
TDK
