Start advertisement hci error

[HinnaX]

Hey,
after starting advertisement I see this error log from hci_core

[00:00:00.029,815] <wrn> bt_hci_core: opcode 0x2027 status 0x12
[00:00:00.029,846] <err> bt_id: Failed to add IRK to controller

The advertisement startet successfully, what means that error message?

[Jared]

Hi,

Which nRF Connect SDK version are you using?

Which IC are you using and what board are you building for? Are you using a development kit?

regards

Jared 

[HinnaX]

Hey,
thanks for your reply.
I'm using the nRF Connect SDK version 2.5.2

I'm using the nrf 52840 and have a custom board for that.

[HinnaX]

Hi,
so other applications working with that custom board and I created a board overlay for that.
But the first time my application starts the advertisement this error message make me a little bit scared.
Maybe this is only a timing issue or something else?

[Jared]

Hi,

Did you try the peripheral UART sample, was it working?

regards

Jared 

[HinnaX]

Yes this example works on board.

The other application also works, but at start of my application at the end the ble advertisement will be startet and the the hci error occures.opcode 0x2027 status 0x12

[Jared]

Hi,

Can you share your projct config file and your code where you start the ble advertisement?

regards

Hi,

Which board are you building for? What is the complete board name that you're using when you build the application?
