Hi Skoon,

Looks like you are getting the Error: NRF_FAULT_ID_APP_MEMACC

"Application invalid memory access. The info parameter will contain 0x00000000, in case of SoftDevice RAM access violation. In case of SoftDevice peripheral register violation the info parameter will contain the sub-region number of PREGION[0], on whose address range the disallowed write access caused the memory access fault."

Hi Martin，

The SDK is nRF5_SDK_15.0.0_a53641a,s132 in this SDK.

The example is ...\nrf52832\nRF5_SDK_15.0.0_a53641a\examples\ble_peripheral\ble_app_uart\pca10040\s132\arm5_no_packs.

I debug it,the id is 0x00001001,I guess it's a hard fault,I will try it again.

Thanks for your advice.

Hi Skoon,

I recommend that you utilize this Online Power Profiler to calculate the power consumption.

I need a little more information about your issue.

What SDK & Softdevice version are you using?
What example is your application based on?
Are you able to get out more info about the error?

Here are some useful guides as well.

Hi Martin，

thank you for your reply,it's useful for me.

now I turn on the DC/DC converter using nrf_power_dcdcen_set(true) and setting POWER_CONFIG_DEFAULT_DCDCEN,but my code is freezen at nrf_power_dcdcen_set.

I noticed that the DC/DC regulator requires an external LC filter to be connected,I will try it.And any suggestion for this?

Can you supply me some reference data on advertising with DC/DC converter .

thanks again!
