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.

Scan
Scans for nearby LE peripherals and broadcasters. If the scan cannot be

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.

protocol provided. The scan will be stopped if the channel is closed.

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).

again.

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.

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.

VERY_FAST |

2 |
