Dear Support,

I had measured power  consumption [( BCM20737, Using External DC-DC down converter(XC9265B1214R-G)]

Power consumption is 130uA ( Advertising Interval 2 sec, Average current 2 minute )

But, BCM920737_LE_TAG4 power consumption is 45uA ( Same condition, Same F/W )

Q1) Why our board is power consumption higher than TAG4?

Q2) Our board's current is changed by Supply Voltage, but TAG4 is not.

       ex) Supply Voltage 3.3V - 100uA, Supply Voltage 3.0V - 35uA, Supply Voltage 2.5V - 22uA.......

The follow picture is our test condition.

If you want our schematic & PCB file, I will send you by e-mail

Thanks for your support.

BR.

Hi namsuk.kim,

For this test, are you using mybeacon and changing the adv int under blecm_startAdv() or hello_sensor() and changing the ble_profile_cfg?
