0.17.0

• core
  • ble: move UUID, MAC and MACAddress into a new ble subpackage. The
    bluetooth package aliases them, so bluetooth.UUID and ble.UUID are the
    same type and existing code keeps working. (#477)
  • ble: move AttributeProtocolError and the ErrAtt* codes into the ble
    subpackage, aliased in the same way. ATT now uses them instead of a second
    copy of the same 17 codes. (#477)
  • ble: rename UUID.bytes() to UUID.BytesLittleEndian(), and add
    ble.UUIDFromBytes and ble.NewMACAddress. (#477)
  • adapter: add SetConnectionStateHandler, which gives the handler a
    ConnectionState with the disconnect reason. SetConnectHandler is
    deprecated, and go fix rewrites its callers. (#518)
  • gap: add ConnectionPriority to ConnectionParams (#472)
  • gattc: export ErrServiceNotFound and ErrCharacteristicNotFound, and
    return them from every backend. (#501)
  • gattc: fix Read, which returned the length of the value instead of the
    bytes copied, so a small buffer caused a panic. It now returns
    io.ErrShortBuffer when the value does not fit. (#497)
• hci
  • hci: move the HCI, L2CAP and ATT protocol code into a new hci subpackage
    that has no build tags, so it builds and unit tests on the host. A board
    supplies an hci.Transport and calls hci.NewStack. (#478)
  • hci: add SetEventHandler and SetLEEventHandler, so that a controller can
    consume an event or an LE subevent that the package does not know, and
    SendVendorCommand for the matching commands. Vendor extensions no longer
    need to live in this repository. (#478)
  • hci: add unit tests, at 87 percent statement coverage. (#476)
  • hci: fix a panic on a Find Information Response, whose format byte was
    treated as an entry length. (#476)
  • hci: bounds check the entry length of a Read By Type Response and a Read By
    Group Type Response, which came off the wire unchecked. (#476)
  • hci: reject an ATT protocol data unit that is too short for its opcode,
    rather than reading past the end of it. (#476)
  • hci: fix ReadBdAddr, which copied the event header into the address. (#476)
  • hci: fix ReadLEBufferSize, which read the raw packet buffer and raised the
    maximum MTU far above what the response buffers hold. (#476)
  • hci: fix MTUReq, which asked for an MTU of zero. (#476)
  • hci: track the negotiated ATT MTU, so GetMTU reports it and a discovery
    response carries more than one attribute. (#476)
  • hci: reject a truncated L2CAP connection parameter update request, which was
    answered as accepted with zeroed parameters. (#476)
  • hci: Transport drops ReadByte, which nothing called. (#478)
  • hci: report the disconnect reason to the connection state handler (#518)
• nordic semi
  • nrf528xx: add SetTxPower to set the advertising transmit power (#475)
  • nrf528xx: add EnableDCSupply to control the DC/DC converters (#475)
  • nrf52840: add Adapter.USBVBusPresent to detect USB cable removal (#487)
  • nrf52: add Adapter.Flash, a flash block device that uses the
    SoftDevice (#489)
  • sd: report the disconnect reason to the connection state handler (#518)
  • softdevice: move the vendored SDK directories into a softdevice
    subdirectory (#482)
• espradio
  • espradio: add the classic ESP32 (#483)
• wasm
  • add a central role backend that uses the Web Bluetooth API (#436)
• darwin
  • darwin: keep services found by earlier DiscoverServices calls (#491)
  • darwin: do not deliver read results to the notification callback (#493)
  • darwin: return ATT errors as AttributeProtocolError (#499)
  • darwin: pass the CoreBluetooth error as the disconnect reason (#518)
• windows
  • windows: do not disconnect in the connection status handler (#481)
  • windows: use ConnectionPriority for the preferred connection
    parameters (#473)
  • windows: return whole service UUIDs in scan results (#504)
  • windows: merge scan responses into scan results (#505)
  • windows: wait for the link in Connect (#507)
  • windows: return an error when characteristic discovery fails (#508)
  • windows: close discovered services when disconnecting (#509)
  • windows: check the read status before using its value, which fixes a
    panic on a refused read (#510)
  • windows: report the ATT error code of a refused read or discovery (#511)
  • windows: call the connect handler when disconnecting (#520)
• examples
  • add a low power beacon example (#475)
  • add the usbvbus example (#487)
  • add the flash example (#489)
  • add a Web Bluetooth example (#436)
• build
  • ci: test every package, and add a faster HCI smoke test (#476)
  • ci: update to the latest Go and use the TinyGo dev container (#486)
  • ci: move the macos-14 job to macos-26 (#517)
  • ci: move the TinyGo and WebAssembly smoke tests to separate
    workflows (#521)
