src.bluetooth_sig.gatt.characteristics.rc_feature¶

RC Feature characteristic (0x2B1D).

Describes the supported features of the Reconnection Configuration server.

Structure: E2E-CRC (uint16) + RC Feature field (3+n octets). The RC Feature field is a variable-length bit field with an extension mechanism via bit 23.
