Examples for IEEE compliant RX_AACK Configuration

This chapter provides configuration examples that will enable the transceiver to act as an IEEE 802.15.4 compliant network node when put into RX_AACK mode. An IEEE 802.15.4 network node can be either a Device, a PAN Coordinator, or a Promiscuous Mode Device/Sniffer.

Use Cases:

• CFG_IEEE_DEVICE
• CFG_IEEE_COORDINATOR
• CFG_IEEE_SNIFFER

CFG_IEEE_DEVICE

The list below describes the configuration of the radio transceiver as an IEEE 802.15.4 device node. The parameters have to be applied to use case PHY_CFG_RX_AACK_EXT.

1. Configure the address filter: panid, short_addr, ext_addr.
2. Configure frame buffer protection: safe_mode.
3. Configure slotted operation: slmode.
4. Configure, which IEEE 802.15.4 frame versions have to be processed: fvn_mode.
5. Disable promiscuous mode: prom_mode = 0.
6. Disable PAN coordinator behavior: coord = 0.
7. Disable short Ack timing: ack_time = 0.
8. Disable processing of reserved frame types: fltr_res_ft = 0, upld_res_ft_mode = 0.
9. Enable automatic acknowledgement frame generation: dis_ack = 0.

Note:

>>  The order of the steps may be changed.
>>  The parameters prom_mode, coord, ack_time, fltr_res_ft, upld_res_ft_mode, dis_ack are configured according to the reset values of the respective registers. Therefore they do not need to be reconfigured after reset.

CFG_IEEE_COORDINATOR

The list below describes the configuration of the radio transceiver as an IEEE 802.15.4 PAN coordinator. The parameters have to be applied to use case PHY_CFG_RX_AACK_EXT.

Compared to a device node, a PAN coordinator implements different address filtering mechanisms, which is described in detail in section section 6.2 (Frame Filter) of the AT86RF212 datasheet.

1. Configure the address filter: panid, short_addr, ext_addr.
2. Configure frame buffer protection: safe_mode.
3. Configure slotted operation: slmode.
4. Configure, which IEEE 802.15.4 frame versions have to be processed: fvn_mode.
5. Disable promiscuous mode: prom_mode = 0.
6. Enable PAN coordinator behavior: coord = 1.
7. Disable short Ack timing: ack_time = 0.
8. Disable processing of reserved frame types: fltr_res_ft = 0, upld_res_ft_mode = 0.
9. Enable automatic acknowledgement frame generation: dis_ack = 0.

Note:

>>  The order of the steps may be changed.
>>  The parameters prom_mode, ack_time, fltr_res_ft, upld_res_ft_mode, dis_ack are configured according to the reset values of the respective registers. Therefore they do not need to be reconfigured after reset.

CFG_IEEE_SNIFFER

The list below describes the configuration of the radio transceiver as an IEEE 802.15.4 device/sniffer. The parameters have to be applied to use case PHY_CFG_RX_AACK_EXT.

Compared to a device node, a radio transceiver in promiscuous mode does not perform address filtering and must not acknowledge received frames.

1. Configure the address filter: panid, short_addr, ext_addr.
2. Configure frame buffer protection: safe_mode.
3. Configure, which IEEE 802.15.4 frame versions have to be processed: fvn_mode.
4. Enable promiscuous mode: prom_mode = 1.
5. Disable PAN coordinator behavior: coord = 0.
6. Disable processing of reserved frame types: fltr_res_ft = 0, upld_res_ft_mode = 0.
7. Disable automatic acknowledgement frame generation: dis_ack = 1.

Note:

>>  The order of the steps may be changed.
>>  Instead of using RX_AACK in promiscuous mode, receiving frames in the RX_ON mode will lead to the same behavior, since no frame filtering is done.
>>  Since no automatic acknowledgement is performed due to dis_ack=1, the parameters slmode and ack_time are ignored. The parameters coord, fltr_res_ft, and upld_res_ft_mode are configured according to the reset values of the respective registers. Therefore they do not need to be reconfigured after reset.
