Functions ¶
This section is empty.
Types ¶
type Field ¶
Field is an advertising field which can be appended to a packet.
func IBeaconData ¶
IBeaconData returns an iBeacon advertising packet with specified parameters.
func ManufacturerData ¶
ManufacturerData is manufacturer specific data.
func Raw ¶
Raw appends the bytes to the current packet. This is helpful for creating new packet from existing packets.
func ServiceData16 ¶
ServiceData16 is service data for a 16bit service uuid
type Packet ¶
type Packet struct {
// contains filtered or unexported fields
}
Packet is an implemntation of ble.AdvPacket for crafting or parsing an advertising packet or scan response. Refer to Supplement to Bluetooth Core Specification | CSSv6, Part A.
func NewRawPacket ¶
NewRawPacket returns a new advertising Packet.
func (*Packet) Append ¶
Append appends a field to the packet. It returns ErrNotFit if the field doesn't fit into the packet, and leaves the packet intact.
func (*Packet) Field ¶
Field returns the field data (excluding the initial length and typ byte). It returns nil, if the specified field is not found.
func (*Packet) ManufacturerData ¶
ManufacturerData returns the ManufacturerData field if it's present. Manufacturer ID may be optionally specified. If not specified, returns first ManufacturerData field. If specified, ManufacturerData matching first key is returned.
