Enumeration Type Documentation

◆ anonymous enum

anonymous enum

#include <zephyr/bluetooth/bluetooth.h>

Advertising options.

Enumerator
BT_LE_ADV_OPT_NONE 

Convenience value when no options are specified.

BT_LE_ADV_OPT_CONNECTABLE 

Advertise as connectable.

Advertise as connectable. If not connectable then the type of advertising is determined by providing scan response data. The advertiser address is determined by the type of advertising and/or enabling privacy CONFIG_BT_PRIVACY .

BT_LE_ADV_OPT_ONE_TIME 

Advertise one time.

Don't try to resume connectable advertising after a connection. This option is only meaningful when used together with BT_LE_ADV_OPT_CONNECTABLE. If set the advertising will be stopped when bt_le_adv_stop() is called or when an incoming (peripheral) connection happens. If this option is not set the stack will take care of keeping advertising enabled even as connections occur. If Advertising directed or the advertiser was started with bt_le_ext_adv_start then this behavior is the default behavior and this flag has no effect.

BT_LE_ADV_OPT_USE_IDENTITY 

Advertise using identity address.

Advertise using the identity address as the advertiser address.

Warning
This will compromise the privacy of the device, so care must be taken when using this option.
Note
The address used for advertising will not be the same as returned by bt_le_oob_get_local, instead bt_id_get should be used to get the LE address.
BT_LE_ADV_OPT_USE_NAME 

Advertise using GAP device name.

Deprecated:
This option will be removed in the near future, see https://github.com/zephyrproject-rtos/zephyr/issues/71686

Include the GAP device name automatically when advertising. By default the GAP device name is put at the end of the scan response data. When advertising using BT_LE_ADV_OPT_EXT_ADV and not BT_LE_ADV_OPT_SCANNABLE then it will be put at the end of the advertising data. If the GAP device name does not fit into advertising data it will be converted to a shortened name if possible. BT_LE_ADV_OPT_FORCE_NAME_IN_AD can be used to force the device name to appear in the advertising data of an advert with scan response data.

The application can set the device name itself by including the following in the advertising data.

BT_DATA(BT_DATA_NAME_COMPLETE, name, sizeof(name) - 1)
BT_LE_ADV_OPT_DIR_MODE_LOW_DUTY 

Low duty cycle directed advertising.

Use low duty directed advertising mode, otherwise high duty mode will be used.

BT_LE_ADV_OPT_DIR_ADDR_RPA 

Directed advertising to privacy-enabled peer.

Enable use of Resolvable Private Address (RPA) as the target address in directed advertisements. This is required if the remote device is privacy-enabled and supports address resolution of the target address in directed advertisement. It is the responsibility of the application to check that the remote device supports address resolution of directed advertisements by reading its Central Address Resolution characteristic.

BT_LE_ADV_OPT_FILTER_SCAN_REQ 

Use filter accept list to filter devices that can request scan response data.

BT_LE_ADV_OPT_FILTER_CONN 

Use filter accept list to filter devices that can connect.

BT_LE_ADV_OPT_NOTIFY_SCAN_REQ 

Notify the application when a scan response data has been sent to an active scanner.

BT_LE_ADV_OPT_SCANNABLE 

Support scan response data.

When used together with BT_LE_ADV_OPT_EXT_ADV then this option cannot be used together with the BT_LE_ADV_OPT_CONNECTABLE option. When used together with BT_LE_ADV_OPT_EXT_ADV then scan response data must be set.

BT_LE_ADV_OPT_EXT_ADV 

Advertise with extended advertising.

This options enables extended advertising in the advertising set. In extended advertising the advertising set will send a small header packet on the three primary advertising channels. This small header points to the advertising data packet that will be sent on one of the 37 secondary advertising channels. The advertiser will send primary advertising on LE 1M PHY, and secondary advertising on LE 2M PHY. Connections will be established on LE 2M PHY.

Without this option the advertiser will send advertising data on the three primary advertising channels.

Note
Enabling this option requires extended advertising support in the peer devices scanning for advertisement packets.
This cannot be used with bt_le_adv_start().
BT_LE_ADV_OPT_NO_2M 

Disable use of LE 2M PHY on the secondary advertising channel.

Disabling the use of LE 2M PHY could be necessary if scanners don't support the LE 2M PHY. The advertiser will send primary advertising on LE 1M PHY, and secondary advertising on LE 1M PHY. Connections will be established on LE 1M PHY.

Note
Cannot be set if BT_LE_ADV_OPT_CODED is set.
Requires BT_LE_ADV_OPT_EXT_ADV.
BT_LE_ADV_OPT_CODED 

Advertise on the LE Coded PHY (Long Range).

The advertiser will send both primary and secondary advertising on the LE Coded PHY. This gives the advertiser increased range with the trade-off of lower data rate and higher power consumption. Connections will be established on LE Coded PHY.

Note
Requires BT_LE_ADV_OPT_EXT_ADV
BT_LE_ADV_OPT_ANONYMOUS 

Advertise without a device address (identity or RPA).

Note
Requires BT_LE_ADV_OPT_EXT_ADV
BT_LE_ADV_OPT_USE_TX_POWER 

Advertise with transmit power.

Note
Requires BT_LE_ADV_OPT_EXT_ADV

Deprecated:
This option will be removed in the near future, see https://github.com/zephyrproject-rtos/zephyr/issues/71686

Will place the GAP device name into the advertising data rather than the scan response data.

Note
Requires BT_LE_ADV_OPT_USE_NAME
BT_LE_ADV_OPT_USE_NRPA 

Advertise using a Non-Resolvable Private Address.

A new NRPA is set when updating the advertising parameters.

This is an advanced feature; most users will want to enable CONFIG_BT_EXT_ADV instead.

#include <zephyr/bluetooth/bluetooth.h>

Enable Bluetooth.

Enable Bluetooth. Must be the called before any calls that require communication with the local Bluetooth hardware.

When CONFIG_BT_SETTINGS is enabled, the application must load the Bluetooth settings after this API call successfully completes before Bluetooth APIs can be used. Loading the settings before calling this function is insufficient. Bluetooth settings can be loaded with settings_load() or settings_load_subtree() with argument "bt". The latter selectively loads only Bluetooth settings and is recommended if settings_load() has been called earlier.

Parameters
cbCallback to notify completion or NULL to perform the enabling synchronously.
Returns
Zero on success or (negative) error code otherwise.

◆ bt_foreach_bond()

◆ bt_id_create()

int bt_id_create ( bt_addr_le_t addr,
uint8_t irk 
)

#include <zephyr/bluetooth/bluetooth.h>

Create a new identity.

Create a new identity using the given address and IRK. This function can be called before calling bt_enable(). However, the new identity will only be stored persistently in flash when this API is used after bt_enable(). The reason is that the persistent settings are loaded after bt_enable() and would therefore cause potential conflicts with the stack blindly overwriting what's stored in flash. The identity will also not be written to flash in case a pre-defined address is provided, since in such a situation the app clearly has some place it got the address from and will be able to repeat the procedure on every power cycle, i.e. it would be redundant to also store the information in flash.

Generating random static address or random IRK is not supported when calling this function before bt_enable().

If the application wants to have the stack randomly generate identities and store them in flash for later recovery, the way to do it would be to first initialize the stack (using bt_enable), then call settings_load(), and after that check with bt_id_get() how many identities were recovered. If an insufficient amount of identities were recovered the app may then call bt_id_create() to create new ones.

If supported by the HCI driver (indicated by setting CONFIG_BT_HCI_SET_PUBLIC_ADDR ), the first call to this function can be used to set the controller's public identity address. This call must happen before calling bt_enable(). Subsequent calls always add/generate random static addresses.

Parameters
addrAddress to use for the new identity. If NULL or initialized to BT_ADDR_LE_ANY the stack will generate a new random static address for the identity and copy it to the given parameter upon return from this function (in case the parameter was non-NULL).
irkIdentity Resolving Key (16 bytes) to be used with this identity. If set to all zeroes or NULL, the stack will generate a random IRK for the identity and copy it back to the parameter upon return from this function (in case the parameter was non-NULL). If privacy CONFIG_BT_PRIVACY is not enabled this parameter must be NULL.
Returns
Identity identifier (>= 0) in case of success, or a negative error code on failure.

◆ bt_id_delete()

int bt_id_delete ( uint8_t  id)

#include <zephyr/bluetooth/bluetooth.h>

Delete an identity.

When given a valid identity this function will disconnect any connections created using it, remove any pairing keys or other data associated with it, and then flag is as deleted, so that it can not be used for any operations. To take back into use the slot the identity was occupying the bt_id_reset() API needs to be used.

Note
the default identity (BT_ID_DEFAULT) cannot be deleted, i.e. this API will return an error if asked to do that.
Parameters
idExisting identity identifier.
Returns
0 in case of success, or a negative error code on failure.

◆ bt_id_get()

void bt_id_get ( bt_addr_le_t addrs,
size_t count 
)

#include <zephyr/bluetooth/bluetooth.h>

Get the currently configured identities.

Returns an array of the currently configured identity addresses. To make sure all available identities can be retrieved, the number of elements in the addrs array should be CONFIG_BT_ID_MAX. The identity identifier that some APIs expect (such as advertising parameters) is simply the index of the identity in the addrs array.

If addrs is passed as NULL, then returned count contains the count of all available identities that can be retrieved with a subsequent call to this function with non-NULL addrs parameter.

Note
Deleted identities may show up as BT_ADDR_LE_ANY in the returned array.
Parameters
addrsArray where to store the configured identities.
countShould be initialized to the array size. Once the function returns it will contain the number of returned identities.

◆ bt_id_reset()

int bt_id_reset ( uint8_t  id,
bt_addr_le_t addr,
uint8_t irk 
)

#include <zephyr/bluetooth/bluetooth.h>

Reset/reclaim an identity for reuse.

The semantics of the addr and irk parameters of this function are the same as with bt_id_create(). The difference is the first id parameter that needs to be an existing identity (if it doesn't exist this function will return an error). When given an existing identity this function will disconnect any connections created using it, remove any pairing keys or other data associated with it, and then create a new identity in the same slot, based on the addr and irk parameters.

Note
the default identity (BT_ID_DEFAULT) cannot be reset, i.e. this API will return an error if asked to do that.
Parameters
idExisting identity identifier.
addrAddress to use for the new identity. If NULL or initialized to BT_ADDR_LE_ANY the stack will generate a new static random address for the identity and copy it to the given parameter upon return from this function (in case the parameter was non-NULL).
irkIdentity Resolving Key (16 bytes) to be used with this identity. If set to all zeroes or NULL, the stack will generate a random IRK for the identity and copy it back to the parameter upon return from this function (in case the parameter was non-NULL). If privacy CONFIG_BT_PRIVACY is not enabled this parameter must be NULL.
Returns
Identity identifier (>= 0) in case of success, or a negative error code on failure.

#include <zephyr/bluetooth/bluetooth.h>

Unregister scanner packet callbacks.

Remove the callback structure from the list of scanner callbacks.

Parameters
cbCallback struct. Must point to memory that remains valid.

◆ bt_le_scan_start()

int bt_le_scan_start ( const struct bt_le_scan_param param,
bt_le_scan_cb_t  cb 
)

#include <zephyr/bluetooth/bluetooth.h>

Start (LE) scanning.

Start LE scanning with given parameters and provide results through the specified callback.

Note
The LE scanner by default does not use the Identity Address of the local device when CONFIG_BT_PRIVACY is disabled. This is to prevent the active scanner from disclosing the identity information when requesting additional information from advertisers. In order to enable directed advertiser reports then CONFIG_BT_SCAN_WITH_IDENTITY must be enabled.
Parameters
paramScan parameters.
cbCallback to notify scan results. May be NULL if callback registration through bt_le_scan_cb_register is preferred.
Returns
Zero on success or error code otherwise, positive in case of protocol error or negative (POSIX) in case of stack internal error.

◆ bt_le_scan_stop()

int bt_le_scan_stop ( void  )

#include <zephyr/bluetooth/bluetooth.h>

Stop (LE) scanning.

Stops ongoing LE scanning.

Returns
Zero on success or error code otherwise, positive in case of protocol error or negative (POSIX) in case of stack internal error.

◆ bt_le_set_chan_map()

int bt_le_set_chan_map ( uint8_t  chan_map[5])

#include <zephyr/bluetooth/bluetooth.h>

Set (LE) channel map.

Parameters
chan_mapChannel map.
Returns
Zero on success or error code otherwise, positive in case of protocol error or negative (POSIX) in case of stack internal error.

◆ bt_le_set_rpa_timeout()

int bt_le_set_rpa_timeout ( uint16_t  new_rpa_timeout)

#include <zephyr/bluetooth/bluetooth.h>

Set the Resolvable Private Address timeout in runtime.

The new RPA timeout value will be used for the next RPA rotation and all subsequent rotations until another override is scheduled with this API.

Initially, the if CONFIG_BT_RPA_TIMEOUT is used as the RPA timeout.

This symbol is linkable if CONFIG_BT_RPA_TIMEOUT_DYNAMIC is enabled.

Parameters
new_rpa_timeoutResolvable Private Address timeout in seconds
Return values
0Success.
-EINVALRPA timeout value is invalid. Valid range is 1s - 3600s.
