Hi Daniel,

Thanks! I'll test tonight and report, but this seems to be right answer.

You need to use the function sd_power_gpregret_set(). When the softdevice is enabled, you have restricted access to the POWER register(see this link), so you need to use the API(sd_power_gpregret_set() in this case).

Hello Javier Cardona

Unfortunately I have not been able to reproduce your error.

Would you be able to upload your code here so I can take a look at it?

If your project is confidential you can create a mypage case at Nordicsemi.com and refer to this case.

Best regards

Jørn Frøysa

I can confirm that the same problem appears on the nrf52 (PCA10040).

Hi RK,

Thanks for the response. Details below:

sdk: nRF5_SDK_13.0.0_04a0bfd softdevice: s132_nrf52_4.0.2_softdevice.hex This is a custom board based on the NRF52832 The software is based on the nrf uart example code. The error is out of the uart debug console. I will also try to run the code on the nrf52-dk and report back to this thread.

Cheers,

you're getting that error where? What software/hardware/SDK etc are you using?
