I am trying to build the simplest nRF52 BLE Peripheral application (Lightbulb use case). I am facing below mentioned errors:

Hi,

Which SDK version are you using? battery_level_char_attr_md was available ut to SDK 15.0.0, from SDK 15.2.0 the security parameters are available directly through bl_rd_sec/bl_cccd_wr_sec/bl_report_rd_sec.

Best regards,
Jørgen

I would recommend that you have a look at one of the existing examples, for instance, ble_app_gls implements the Battery service.

In short, set the security requirement in the inti structure to one defined in security_req_t.

Can you deeply explain how to edit in code. because i am getting the same problem. i am using same SDK_15.3

[Jørgen Holmefjord]

If you look in the example I suggested, it is shown exactly how to do this.

    // Here the sec level for the Battery Service can be changed/increased.
    bas_init.bl_rd_sec        = SEC_OPEN;
    bas_init.bl_cccd_wr_sec   = SEC_OPEN;
    bas_init.bl_report_rd_sec = SEC_OPEN;
