Types

type Client 

type Client struct {
	// contains filtered or unexported fields
}

Client implementa an Attribute Protocol Client.

func NewClient 

func NewClient(l2c ble.Conn, h NotificationHandler) *Client

NewClient returns an Attribute Protocol Client.

func (*Client) ExchangeMTU 

func (c *Client) ExchangeMTU(clientRxMTU int) (serverRxMTU int, err error)

ExchangeMTU informs the server of the client’s maximum receive MTU size and request the server to respond with its maximum receive MTU size. [Vol 3, Part F, 3.4.2.1]

func (*Client) ExecuteWrite 

func (c *Client) ExecuteWrite(flags uint8) error

ExecuteWrite requests the server to write or cancel the write of all the prepared values currently held in the prepare queue from this Client. This request shall be handled by the server as an atomic operation. [Vol 3, Part F, 3.4.6.3 & 3.4.6.4]

func (*Client) FindInformation 

func (c *Client) FindInformation(starth, endh uint16) (fmt int, data []byte, err error)

FindInformation obtains the mapping of attribute handles with their associated types. This allows a Client to discover the list of attributes and their types on a server. [Vol 3, Part F, 3.4.3.1 & 3.4.3.2]

func (*Client) Loop 

func (c *Client) Loop()

Loop ...

func (*Client) PrepareWrite 

func (c *Client) PrepareWrite(handle uint16, offset uint16, value []byte) (uint16, uint16, []byte, error)

PrepareWrite requests the server to prepare to write the value of an attribute. The server will respond to this request with a Prepare Write Response, so that the Client can verify that the value was received correctly. [Vol 3, Part F, 3.4.6.1 & 3.4.6.2]

func (*Client) Read 

func (c *Client) Read(handle uint16) ([]byte, error)

Read requests the server to read the value of an attribute and return its value in a Read Response. [Vol 3, Part F, 3.4.4.3 & 3.4.4.4]

func (*Client) ReadBlob 

func (c *Client) ReadBlob(handle, offset uint16) ([]byte, error)

ReadBlob requests the server to read part of the value of an attribute at a given offset and return a specific part of the value in a Read Blob Response. [Vol 3, Part F, 3.4.4.5 & 3.4.4.6]

func (*Client) ReadByGroupType 

func (c *Client) ReadByGroupType(starth, endh uint16, uuid ble.UUID) (int, []byte, error)

ReadByGroupType obtains the values of attributes where the attribute type is known, the type of a grouping attribute as defined by a higher layer specification, but the handle is not known. [Vol 3, Part F, 3.4.4.9 & 3.4.4.10]

func (*Client) ReadByType

func (*Client) ReadMultiple 

func (c *Client) ReadMultiple(handles []uint16) ([]byte, error)

ReadMultiple requests the server to read two or more values of a set of attributes and return their values in a Read Multiple Response. Only values that have a known fixed size can be read, with the exception of the last value that can have a variable length. The knowledge of whether attributes have a known fixed size is defined in a higher layer specification. [Vol 3, Part F, 3.4.4.7 & 3.4.4.8]

func (*Client) SignedWrite 

func (c *Client) SignedWrite(handle uint16, value []byte, signature [12]byte) error

func (*Client) Write 

func (c *Client) Write(handle uint16, value []byte) error

Write requests the server to write the value of an attribute and acknowledge that this has been achieved in a Write Response. [Vol 3, Part F, 3.4.5.1 & 3.4.5.2]

func (*Client) WriteCommand 

func (c *Client) WriteCommand(handle uint16, value []byte) error
