bluetooth_clocks.devices package#

Device-specific Bluetooth clock support.

Each submodule in this package implements support for a specific type of Bluetooth clock.

Each class in these submodules implements support for a specific model Bluetooth clock.

For instance, the bluetooth_clocks.devices.thermopro module has classes bluetooth_clocks.devices.thermopro.TP358 and bluetooth_clocks.devices.thermopro.TP393 for the ThermoPro TP358 and TP393, respectively.

TIME_GET_FORMAT: ClassVar[str | None] = '<HBBBBBBB'#

The format string to convert bytes read from the Current Time Service to a time.

This starts with an unsigned short in little-endian format, followed by seven bytes.

TIME_SET_FORMAT: ClassVar[str] = '<HBBBBBBBB'#
