This section describes, how the radio transceiver is used in the Extended Operating Mode. There are the modes TX_ARET for automatic frame transmissions and RX_AACK for automatic frame receptions, which include IEEE 802.15.4 compliant channel access, address filtering, FCS check and acknowledgement frame handling.
- TX_ARET
A frame transmission in TX_ARET mode is a combined transaction performing CSMA-CA algorithm , transmiting a frame and receiving and processing the associated ACK frame if necessary.
- RX_AACK
- A frame reception in RX_AACK mode is a combination of receiving a frame, matching it against the addressfilter, checking the FCS and transmitting the ACK frame if necessary.
The transaction flow diagrams for both modes are given in the AT86RF230 data sheet.
