standard

This module provides Service classes for BLE defined standard services.

class AppearanceCharacteristic(**kwargs)

What type of device it is

class GenericAccess(*, service: Service | None = None, secondary: bool = False, **initial_values)

Required service that provides basic device information

class GenericAttribute(*, service: Service | None = None, secondary: bool = False, **initial_values)

Required service that provides notifications when Services change

class BatteryService(*, service: Service | None = None, secondary: bool = False, **initial_values)

Provides battery level information

class CurrentTimeService(*, service: Service | None = None, secondary: bool = False, **initial_values)

Provides the current time.

current_time

A tuple describing the current time: (year, month, day, hour, minute, second, weekday, subsecond, adjust_reason)

local_time_info

(timezone, dst_offset)

Type:

A tuple of location information

property struct_time: struct_time

The current time as a time.struct_time. Day of year and whether DST is in effect are always -1.

device_info

class DeviceInfoService(*, manufacturer: str | None = None, software_revision: str | None = None, model_number: str | None = None, serial_number: str | None = None, firmware_revision: str | None = None, hardware_revision: str | None = None, service: _bleio.Service | None = None)

provides mouse, keyboard, and consumer control devices.

Type:

Default HID descriptor

class ReportIn(service: Service, report_id: int, usage_page: bytes, usage: bytes, *, max_length: int)

A single HID report that transmits HID data into a client.

send_report(report: Dict) → None

Send a report to the peers

class ReportOut(service: Service, report_id: int, usage_page: bytes, usage: bytes, *, max_length: int)

A single HID report that receives HID data from a client.

property report: Dict

The HID OUT report

Provide devices for HID over BLE.

Parameters:

hid_descriptor (str) – USB HID descriptor that describes the structure of the reports. Known as the report map in BLE HID.

Example:

from adafruit_ble.hid_server import HIDServer

hid = HIDServer()

protocol_mode

boot (0) or report (1)

Type:

Protocol mode

hid_information

Hid information including version, country code and flags.

report_map

This is the USB HID descriptor (not to be confused with a BLE Descriptor). It describes which report characteristic are what.

suspended

Controls whether the device should be suspended (0) or not (1).
