5.1.3 Connection Request

This section describes the power profile of the SAM R30 Mi-Wi sleeping end device measured during the transmission of the connection request and the reception of the connection response.

  1. A – Connection request TX
  2. B – RX to receive connection response from PAN coordinator
  3. C – Reception of connection response from PAN coordinator
  4. D – MAC ACK TX for the received connection response
  5. E – Transmission of periodic data request followed by periodic application data
