src.bluetooth_sig.gatt.characteristics.esl_address

ESL Address characteristic implementation.

Per ESL Service v1.0 §3.1.1, the ESL Address is a 16-bit value:

  • Bits 0-7: ESL_ID (8-bit, range 0x00-0xFE; 0xFF = Broadcast Address)

  • Bits 8-14: Group_ID (7-bit, range 0-127)

  • Bit 15: RFU (Reserved for Future Use)
