Thanks Ashish and Bjorn

effectively, i am in debug mode (i'm forget it), I have to reset it.

Bjorn I will check the Flash storage..

Hi Ricardo,

are you using the bootloader from a offical Nordic SDK or is the bootloader provided by Mbed? It could sound like the bootloader you're using does not disable the peripherals its using before jumping to the application. Of any peripheral using the HFCLK is used in the bootloader and not unintialized prior to the bootloader jumping to the application, then this peripheral and the HFCLK will be running in the application as well.

Resetting the device will reset the peripherals, so thats why you see the current consumption returning to normal.

No, I do not think we have such an example, but you should be able to modify one of the flash storage examples in the nRF5 SDK v12.3.0 to do this.

Best regards

Bjørn

Hi,

So if I understand you correctly, when you program your board, it works fine but the sleep current is high. And after a reset, the sleep current is back to normal again. Then as far as I know, it's completely fine.

When you program the NRF51822, it goes in debug mode, where the current will be a little high. It will come out of debug mode only after a reset. After the reset, the NRF won't be in the debug mode, and thus you will have lower power consumption.
