After BLE connection with a central device, peer_manager_pds has an error "Could not write data to flash".

[hiro.maezawa]

I'm trying to make a BLE app with nRF52832 DK, SDK v16.0.0, based on ble_app_hrs example.

After pairing on central device (smart phone), or CONNECT on nRF Connect app and enabled the indication, I got an peer_manager_pds error message.

<error> app: End of error report

Returned code 0x8601 means FDS_ERR_NOT_INITIALIZED in my understand.

And fds_init() may be called in peer_manager_init() > pm_init() > pds_init().

So I don't know why this error occurs.

Please help any hints or suggenstions what should I check?

Hi, I'll add more information.

In my project, the app which based on ble_app_hrt is merged with ble_app_hts. So GATT Queue module has been  added to ble_app_hrs. Dose it have any adversely affect?

And ble_app_hrs can show nrf_sdh_soc log, but my project cannot even though setting NRF_SDH_SOC_LOG_ENABLED in sdk_config.h.

[hiro.maezawa]

Sorry, it was my misstake.

A sourcefile nrf_sdh_soc.c lacked in my project. So, my problem is cleared.

But I wonder why there is no warning or error message in making process even I configured NRF_SDH_SOC_ENABLED.

I hope this will be explained.

Thank you.

I am not sure what locked file means inside the project? How did you unlock it?

[hiro.maezawa]

Hi, it's not 'lock' but  I mean 'lack'. 

A sourcefile nrf_sdh_soc.c was missing in my project.

  Is this an expression that is easier to understand for you?
