About BLE Link Layer (LL)

The BLE Link Layer is the core radio protocol state machine. Header fields identify PDU framing and reliability sequencing behavior for connected data channels.

BLE Link Layer handles advertising events, connection events, channel hopping, and reliable data transfer primitives over the radio.

BLE Link Layer (LL) Header Structure

  • LL Header byte 0: LLID + control bits (NESN/SN/MD).
  • LL Header byte 1: payload length.
