Very high DWM1001 current consumption in OFF+SLEEP mode

Hi Yves,

My objective is to have a tag in real low power when it leaves the network, i.e. when it is out of UWB and BLE range to any other node.

1.- So, I start with a tag in low power mode (not responsive) working correctly: 15uA base current line. BLE is enabled in the tag.
2.- Then, I cut the power to every other node on the network (initiator and anchors)
3.- In this situation, is when the tag shows this BLE activity, and the base line is 425uA:

As this base line is too high, I follow the next procedure:

1.- I start again with a tag in low power mode working correctly: 15uA.
2.- Then, I cut the power to every other node on the network
3.- I send via UART a wakeup byte
4.- I send an Offline command: 05 02 8C 00
5.- I send a sleep command: 0A 00
6.- Finnally I send a reset command: 14 00
7.- In this situation, the tag shows no BLE activity, but the base line is 280uA (as you can see in the image in my second post)

If I send an Off command and a sleep command as you stated in the last post, the tag will not be in real Offline state untill a reset command is sent.So, the state of the tag will be the same as if no Offline command was sent.

Any advice is wellcome

Best regards
Epenciso
