nrf5340 call bt_disable always return err

Hi Devzone:

I have create our own board based on nrf5340dk_nrf5340, all are the same , just the pin configure and some perpherail devices on bus are not the same.

I configure bluetooth as follows,

#bluetooth

CONFIG_BT=y

CONFIG_BT_PERIPHERAL=y

CONFIG_BT_EXT_ADV=y

CONFIG_BT_EXT_ADV_MAX_ADV_SET=3

CONFIG_BT_DEVICE_NAME_DYNAMIC=y

CONFIG_BT_DEVICE_APPEARANCE=833

#bluetooth Enable the NUS service

CONFIG_BT_NUS=y

#bluetooth Enable bonding

CONFIG_SETTINGS=y

CONFIG_BT_SETTINGS=y

CONFIG_FLASH=y

CONFIG_FLASH_MAP=y

CONFIG_NVS=y

#bluetooth scan

CONFIG_BT_CENTRAL=y

I call bt_enable to enable bluetooth, and create adv, but not start adv.

err = bt_enable(bt_ready);

then when I call bt_disable, it always return error.

err = bt_disable();

How can I disable bluetooth?

Hi,

Disabling the Bluetooth stack with bt_disable() is not supported. If what you want to do is just to stop any Bluetooth activity, you can achieve that by terminating any active connections and stopping scanning and advertising. If you need low-level access to the radio you may want to look at MPSL timeslots. If you actually have a need for disabling the Bluetooth stack, you would need to perform a reset (see this post).
