Hello,

I am using BluNRG-1 module with Stack v1.0.My clock source is 'LS_SOURCE = LS_SOURCE_INTERNAL_RO', the module has no external oscillator.

I used the following code to lower the power consumption, as it is adviced in 'BlueNRG-1 and BlueNRG-2 low power modes.pdf' and I am getting average current consumption about 120 uA.

BlueNRG_Sleep(SLEEPMODE_WAKETIMER,

WAKEUP_IO13, WAKEUP_IO_LOW, 0);I also tried 

SLEEPMODE_NO

TIMER option with the same current consumption: 120 uA.

The advertising interval in my application has been set to 1000 ms.

Can you please advice, what setting will make the power consumption below 20 uA?

In advance thanks,

Evgeny

As a first step I advise to use this software

  write your connection settings then compare it with measurement. What equipment do you use for measurement?
