PROTOCOLS

AdvertisedPeripheral

Defined in fuchsia.bluetooth.le/peripheral.fidl

Protocol that is valid for the duration of advertising. The caller can close the protocol to stop advertising. If the system internally stops advertising for any reason, the protocol will be closed to communicate this to the client.

OnConnected

Called when a remote LE central connects to this peripheral when connectable advertising is enabled via fuchsia.bluetooth.le/Peripheral.Advertise. When this call is made, the system has paused advertising, and will not continue until it receives a response.

The returned fuchsia.bluetooth.le/Connection protocol can be used to interact with the peer. It also represents a peripheral's ownership over the connection: the client can drop the protocol to request a disconnection. Similarly, the protocol is closed by the system to indicate that the connection to the peer has been lost.

  • request peer Information about the central that initiated the connection.
  • request connection Represents the connection.
  • response An empty response should be sent to acknowledge the connection and resume advertising (for flow control).

AdvertisingHandle

Defined in fuchsia.bluetooth.le/peripheral.fidl

Capability that is valid for the duration of advertising. The caller can close the handle to stop advertising. If the system internally stops advertising for any reason, the handle will be closed to communicate this to the client.

Central

Defined in fuchsia.bluetooth.le/central.fidl

Connect

Connect to the peer with the given identifier.

The requested fuchsia.bluetooth.le/Connection represents the client's interest on the LE connection to the peer. Closing the channel removes interest, but may not result in disconnection if another client holds a valid fuchsia.bluetooth.le/Connection to the same peer.

The fuchsia.bluetooth.le/Connection handle will be closed by the system if the connection to the peer is lost or an error occurs.

The following epitaphs may be sent by the server on error: + INVALID_ARGS: Some of the parameters are invalid. + ALREADY_BOUND: A Connection to the peer already exists for this Central. The existing Connection should be used. + NOT_CONNECTED: A connection could not be established. + CONNECTION_RESET: The peer disconnected.

  • request id Identifier of the peer to initiate a connection to.
  • request options Options used to configure the connection.
  • request handle Handle that remains valid for the duration of this connection.

Scan

Scans for nearby LE peripherals and broadcasters. If the scan cannot be initiated, then result_watcher will be closed with an epitaph.

A Central client is allowed to have only one active scan at a time. Accordingly, only one Scan request can be outstanding at a time. Additional calls to Scan will fail.

The lifetime of the scan session is tied to the result_watcher protocol provided. The scan will be stopped if the channel is closed.

Once a scan is started, the fuchsia.bluetooth.le/ScanResultWatcher can be used to watch for scan results.

  • request options Options used to configure the scan session.
  • request result_watcher Protocol that remains valid for the duration of this scan session.
  • response An empty response will be sent to acknowledge the scan has stopped.

The following epitaphs may be sent by the server on error:

  • error ALREADY_EXISTS: A scan is already in progress. Each Central protocol is only allowed 1 active scan.
  • error INVALID_ARGS: Some of the scan options are invalid. See the ScanOptions documentation.
  • error INTERNAL: An internal error occurred and a scan could not be started.

StartScan

Initiates a scan session for nearby peripherals and broadcasters. Discovered devices will be reported via CentralDelegate.OnDeviceDiscovered(). If a scan session is already in progress, filter will replace the existing session's filter.

If filter is null or empty (i.e. none of its fields has been populated) then the delegate will be notified for all discoverable devices that are found. This is not recommended; clients should generally filter results by at least one of filter.service_uuids, filter.service_data, and/or filter.manufacturer_identifier.

Protocol that represents the connection to a peer. This can be used to interact with GATT services and establish L2CAP channels.

This lifetime of this capability is tied to that of the LE connection it represents. Closing the channel results in a disconnection if no other clients hold a Connection to the same peer.

Peripheral

Defined in fuchsia.bluetooth.le/peripheral.fidl

Advertise

Start advertising continuously as a LE peripheral. If advertising cannot be initiated then advertised_peripheral will be closed and an error will be returned.

This method may be called any number of times. To reconfigure an advertisement, first close the original advertisement and then initiate a new advertisement after an empty response is returned.

If the client closes its end of the fuchsia.bluetooth.le/AdvertisedPeripheral channel, advertising will be stopped. If the handle is closed before the request is fulfilled, advertising may be briefly enabled before it is terminated. AdvertisedPeripheral lifetime is bounded by the lifetime of the Peripheral protocol, but this may be changed in the future (fxbug.dev/77644).

  • request parameters Parameters used while configuring the advertising instance.
  • request advertised_peripheral Protocol that remains valid for the duration of this advertising session.
  • response An empty response will be sent when the advertisement is successfully stopped (due to release of the advertised_peripheral protocol). To prevent overlapping similar advertisements and transient errors with limited advertising resources, waiting for a response is recommended before calling Advertise again.
  • error If an error occurs, advertised_peripheral will be closed and a PeripheralError will be returned.

StartAdvertising

Start advertising as a LE peripheral. An empty response is sent to indicate when advertising has successfully initiated. If advertising cannot be initiated, then the response will contain a fuchsia.bluetooth.le/PeripheralError.

This method can get called any number of times and successive calls can be made to reconfigure the advertising parameters. However only the most recent fuchsia.bluetooth.le/AdvertisingHandle will remain valid.

An instance of fuchsia.bluetooth.le/Peripheral can only have one active advertisement at a time. Clients must obtain multiple Peripheral instances for multiple simultaneous advertisements.

If the client closes its end of the fuchsia.bluetooth.le/AdvertisingHandle channel, advertising will be stopped. If the handle is closed before the request is fulfilled, advertising will be briefly enabled before it is terminated.

  • request parameters Parameters used while configuring the advertising instance.

Represents an active scan procedure. This protocol remains valid for the duration of a scan and can be used to obtain scan results. The client can close the protocol to stop scanning. If a scan is stopped by the system, the protocol will be closed with the epitaph CANCELED to communicate this to the client.

Watch

Returns a list of all LE peers that satisfy the filters indicated in ScanOptions. The first response(s) will return matching discovered peers immediately. Subsequent calls receive a response only when peers have been scanned or updated since the last call. If a second call to Watch is erronously sent while one call is already pending, the scan will be canceled and the protocol will be closed.

ENUMS

AdvertisingModeHint strict

Type: uint8

Defined in fuchsia.bluetooth.le/peripheral.fidl

A client can indicate the transmission rate of advertising packets by specifying a mode. The mode provides a hint to the system when configuring the controller with advertising interval and window parameters.

The mode affects how quickly a scanner or central is able to discover the peripheral; however it can have an adverse effect on power consumption. While the system will try to honor a client's request, it is not guaranteed to do so.

NameValueDescription
1

Advertise with a very short interval and window for fast discovery at the cost of higher power consumption. This corresponds to a 30-60ms interval on the 1M PHYs and 90-180ms on the coded PHY.
2

Advertise with a short interval and window that uses less power than VERY_FAST. This corresponds to a 100-150ms interval on the 1M PHYs and 300-450ms on the coded PHY.
3

Advertise with a moderate interval and window. This corresponds to 1-1.2s on the 1M PHYs and 3s on the coded PHY.

Type: uint32

Defined in fuchsia.bluetooth.le/central.fidl

NameValueDescription
1

The request was aborted.
2

AdvertisingParameters

Defined in fuchsia.bluetooth.le/peripheral.fidl

Represents the parameters for configuring advertisements.

OrdinalFieldTypeDescription
data AdvertisingData

The fields that will be encoded in the data section of advertising packets.

This field is required.
scan_response AdvertisingData

The fields that are to be sent in a scan response packet. Clients may use this to send additional data that does not fit inside an advertising packet on platforms that do not support the advertising data length extensions.

If present advertisements will be configured to be scannable.
mode_hint AdvertisingModeHint

The desired advertising frequency. See fuchsia.bluetooth.le/AdvertisingModeHint. Defaults to fuchsia.bluetooth.le/AdvertisingModeHint.SLOW if not present.
connectable bool

If present and true then the controller will broadcast connectable advertisements which allows remote LE centrals to initiate a connection to the Peripheral. If false or otherwise not present then the advertisements will be non-connectable.

DEPRECATED - Prefer to use the connection_options field for new code.
connection_options ConnectionOptions

If present, the controller will broadcast connectable advertisements which allow peers to initiate connections to the Peripheral. The fields of ConnectionOptions will configure any connections set up from advertising.

ConnectionOptions

Defined in fuchsia.bluetooth.le/connection_options.fidl

Represents parameters that are set on a per-connection basis by FIDL protocols that create Low Energy connections.
