Typedefs

typedef void (*bt_ready_cb_t)(int err)

Callback for notifying that Bluetooth has been enabled.

Param err:

zero on success or (negative) error code otherwise.

typedef void bt_le_scan_cb_t(const bt_addr_le_t *addr, int8_t rssi, uint8_t adv_type, struct net_buf_simple *buf)

Callback type for reporting LE scan results.

A function of this type is given to the bt_le_scan_start() function and will be called for any discovered LE device.

Param addr:

Advertiser LE address and type.

Param rssi:

Strength of advertiser signal.

Param adv_type:

Type of advertising response from advertiser. Uses the BT_GAP_ADV_TYPE_* values.

Param buf:

Buffer containing advertiser data.

typedef void bt_br_discovery_cb_t(struct bt_br_discovery_result *results, size_t count)

Callback type for reporting BR/EDR discovery (inquiry) results.

A callback of this type is given to the bt_br_discovery_start() function and will be called at the end of the discovery with information about found devices populated in the results array.

Param results:

Storage used for discovery results

Param count:

Number of valid discovery results.

Enums

enum bt_le_adv_option

Advertising options

Values:

enumerator BT_LE_ADV_OPT_NONE

Convenience value when no options are specified.

enumerator 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.

enumerator 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.

enumerator BT_LE_ADV_OPT_USE_IDENTITY

Advertise using identity address.

Advertise using the identity address as the advertiser address.

备注

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.

警告

This will compromise the privacy of the device, so care must be taken when using this option.

enumerator BT_LE_ADV_OPT_USE_NAME

Advertise using GAP device name.

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)

enumerator 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.

enumerator 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.

enumerator BT_LE_ADV_OPT_FILTER_SCAN_REQ

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

enumerator BT_LE_ADV_OPT_FILTER_CONN

Use filter accept list to filter devices that can connect.

enumerator BT_LE_ADV_OPT_NOTIFY_SCAN_REQ

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

enumerator 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.

enumerator 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.

备注

Enabling this option requires extended advertising support in the peer devices scanning for advertisement packets.

enumerator 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.

备注

Cannot be set if BT_LE_ADV_OPT_CODED is set.

备注

Requires BT_LE_ADV_OPT_EXT_ADV.

enumerator 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.

备注

Requires BT_LE_ADV_OPT_EXT_ADV

enumerator BT_LE_ADV_OPT_ANONYMOUS

Advertise without a device address (identity or RPA).

备注

Requires BT_LE_ADV_OPT_EXT_ADV

Functions

int bt_enable(bt_ready_cb_t cb)

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.

参数:

cb – Callback to notify completion or NULL to perform the enabling synchronously.

返回:

Zero on success or (negative) error code otherwise.

int bt_disable(void)

Disable Bluetooth.

Disable Bluetooth. Can’t be called before bt_enable has completed.

Close and release HCI resources. Result is architecture dependent.

返回:

Zero on success or (negative) error code otherwise.

bool bt_is_ready(void)

Check if Bluetooth is ready.

返回:

true when Bluetooth is ready, false otherwise

int bt_set_name(const char *name)

Set Bluetooth Device Name.

Set Bluetooth GAP Device Name.

When advertising with device name in the advertising data the name should be updated by calling bt_le_adv_update_data or bt_le_ext_adv_set_data.

参见

CONFIG_BT_DEVICE_NAME_MAX.

备注

Requires CONFIG_BT_DEVICE_NAME_DYNAMIC.

参数:

name – New name

返回:

Zero on success or (negative) error code otherwise.

const char *bt_get_name(void)

Get Bluetooth Device Name.

Get Bluetooth GAP Device Name.

返回:

Bluetooth Device Name

uint16_t bt_get_appearance(void)

Get local Bluetooth appearance.

Bluetooth Appearance is a description of the external appearance of a device in terms of an Appearance Value.

参见

https://specificationrefs.bluetooth.com/assigned-values/Appearance%20Values.pdf

返回:

Appearance Value of local Bluetooth host.

int bt_set_appearance(uint16_t new_appearance)

Set local Bluetooth appearance.

Automatically preserves the new appearance across reboots if CONFIG_BT_SETTINGS is enabled.

This symbol is linkable if CONFIG_BT_DEVICE_APPEARANCE_DYNAMIC is enabled.

参数:

new_appearance – Appearance Value

返回值:

• 0 – Success.

• other – Persistent storage failed. Appearance was not updated.

void bt_id_get(bt_addr_le_t *addrs, size_t *count)

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.

备注

Deleted identities may show up as BT_ADDR_LE_ANY in the returned array.

参数:

• addrs – Array where to store the configured identities.

• count – Should be initialized to the array size. Once the function returns it will contain the number of returned identities.

int bt_id_create(bt_addr_le_t *addr, uint8_t *irk)

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.

参数:

• addr – Address 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).

• irk – Identity 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.

返回:

Identity identifier (>= 0) in case of success, or a negative error code on failure.

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

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.

备注

the default identity (BT_ID_DEFAULT) cannot be reset, i.e. this API will return an error if asked to do that.

参数:

• id – Existing identity identifier.

• addr – Address 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).

• irk – Identity 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.

返回:

Identity identifier (>= 0) in case of success, or a negative error code on failure.

int bt_id_delete(uint8_t id)

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.

备注

the default identity (BT_ID_DEFAULT) cannot be deleted, i.e. this API will return an error if asked to do that.

参数:

id – Existing identity identifier.

返回:

0 in case of success, or a negative error code on failure.

size_t bt_data_get_len(const struct bt_data data[], size_t data_count)

Get the total size (in bytes) of a given set of bt_data structures.

参数:

• data – [in] Array of bt_data structures.

• data_count – [in] Number of bt_data structures in data.

返回:

Size of the concatenated data, built from the bt_data structure set.

size_t bt_data_serialize(const struct bt_data *input, uint8_t *output)

The data are formatted according to the Bluetooth Core Specification v. 5.4, vol. 3, part C, 11.

参数:

• input – [in] Single bt_data structure to read from.

• output – [out] Buffer large enough to store the advertising structure in input. The size of it must be at least the size of the `input->data_len + 2` (for the type and the length).

返回:

Number of bytes written in output.

int bt_le_adv_start(const struct bt_le_adv_param *param, const struct bt_data *ad, size_t ad_len, const struct bt_data *sd, size_t sd_len)

Start advertising.

Set advertisement data, scan response data, advertisement parameters and start advertising.

When the advertisement parameter peer address has been set the advertising will be directed to the peer. In this case advertisement data and scan response data parameters are ignored. If the mode is high duty cycle the timeout will be BT_GAP_ADV_HIGH_DUTY_CYCLE_MAX_TIMEOUT.

参数:

• param – Advertising parameters.

• ad – Data to be used in advertisement packets.

• ad_len – Number of elements in ad

• sd – Data to be used in scan response packets.

• sd_len – Number of elements in sd

返回:

Zero on success or (negative) error code otherwise.

返回:

-ENOMEM No free connection objects available for connectable advertiser.

返回:

-ECONNREFUSED When connectable advertising is requested and there is already maximum number of connections established in the controller. This error code is only guaranteed when using Zephyr controller, for other controllers code returned in this case may be -EIO.

• cb – [in] Callback struct to notify about advertiser activity. Can be NULL. Must point to valid memory during the lifetime of the advertising set.

• adv – [out] Valid advertising set object on success.

返回:

Zero on success or (negative) error code otherwise.

int bt_le_ext_adv_start(struct bt_le_ext_adv *adv, struct bt_le_ext_adv_start_param *param)

Start advertising with the given advertising set.

If the advertiser is limited by either the timeout or number of advertising events the application will be notified by the advertiser sent callback once the limit is reached. If the advertiser is limited by both the timeout and the number of advertising events then the limit that is reached first will stop the advertiser.

参数:

• adv – Advertising set object.

• param – Advertise start parameters.

int bt_le_ext_adv_stop(struct bt_le_ext_adv *adv)

Stop advertising with the given advertising set.

Set advertisement data or scan response data. If the advertising set is currently advertising then the advertising data will be updated in subsequent advertising events.

When both BT_LE_ADV_OPT_EXT_ADV and BT_LE_ADV_OPT_SCANNABLE are enabled then advertising data is ignored. When BT_LE_ADV_OPT_SCANNABLE is not enabled then scan response data is ignored.

If the advertising set has been configured to send advertising data on the primary advertising channels then the maximum data length is BT_GAP_ADV_MAX_ADV_DATA_LEN bytes. If the advertising set has been configured for extended advertising, then the maximum data length is defined by the controller with the maximum possible of BT_GAP_ADV_MAX_EXT_ADV_DATA_LEN bytes.

备注

Not all scanners support extended data length advertising data.

备注

When updating the advertising data while advertising the advertising data and scan response data length must be smaller or equal to what can be fit in a single advertising packet. Otherwise the advertiser must be stopped.
