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?
