I am using DWM1001-Dev for an indoor Asset tracking project. Presently I have 23 Anchors, 3 Gateways and 5 Tags configured with a RTLS network. Anchors are hardwired and there is no power issue.
The tags are consuming 29mA of current with a stationary update rate of 30s. The battery that I’m using is of standard capacity of 1600mAh. With this consuption rate, I have only a battery backup of exactly 2 days. How could I decrease the power consumption. With this consumption rate, the project cannot be carried out because of the high cost of maintaining the battery.
I have turned off the LEDs, and desoldered the J16 jumper to cut the power to onboard J - Link. In this configuration, the Tag is consuming 19mA of current with a stationary update of 30s and a battery backup of nearly 4 days.
Is there anyother way to reduce the power consumption of the Tag? I am looking for a battery backup of atleast 10 days with a standard 1600mAh battery.
