src.bluetooth_sig.gatt.characteristics.rc_settings

RC Settings characteristic (0x2B1E).

Structure per RCS v1.0.1, Section 3.2 (Table 3.4):

Length (uint8, 1 octet) + Settings (2 octets) + [E2E-CRC (uint16, 0 or 2 octets)].

Settings bitfield (Table 3.5):

Byte 0, bit 1: LESC Only Byte 0, bit 2: Use OOB Pairing Byte 0, bit 4: Ready for Disconnect Byte 0, bit 5: Limited Access Byte 0, bit 6: Access Permitted Byte 1, bits 0-1: Advertisement Mode (2-bit field)
