Hi Vidar,

I have just found the reason: In my application, once disconnected and every 10s, it starts advertising. When wrong passkey was introduced, the application was not waiting for the BLE_GAP_EVT_DISCONNECTED event, and advertising was sure started before receiving this event. Now, I wait for this event to start advertising.

Thank you so much.

Dani.

Hi Dani,

When do you call ble_advertising_init() and get invalid state in return? This function is usually called just once on startup, so I don't see how it is related to the reset you mentioned in your first post.

Do you have any debug logs that shows when the device is reset?

Hi,

In what regards the reset reason I'm observing: ble_advertising_init gives NRF_ERROR_INVALID_STATE.

Dani.
