bt_hci_core: bt_enable: No HCI driver registered Bluetooth init failed (err -19)

Hi, I'm having some problems with the BLE role peripheral not being able to play ads and not being able to enable bluetooth. When I upgraded from sdk v2.4.2 to v2.6.0 it seems to no longer be able to initiate bluetooth and play ads. fox. Besides, reading the device's MAC Address ble seems to be no longer possible when using the bt_read_static_addr function and it is not possible to change the advertising name.
<err> bt_hci_core: bt_enable: No HCI driver registered
Bluetooth init failed (err -19)

Best regards!

Hi

What sample is your project based on exactly? This error points to there not being an HCI driver registered at all. Can you confirm that CONFIG_BT_HCI=y is set in your prj.conf, as well as upload what Bluetooth HCI driver is used with CONFIG_BT_HCI_BUS_TYPE. 

Best regards,

Simon
