Macros

OPENTHREAD_CONFIG_CCA_FAILURE_RATE_AVERAGING_WINDOW

 OPENTHREAD_CONFIG_CCA_FAILURE_RATE_AVERAGING_WINDOW 512

OpenThread's MAC implementation maintains the average failure rate of CCA (Clear Channel Assessment) operation on frame transmissions.

This value specifies the window (in terms of number of transmissions or samples) over which the average rate is maintained. Practically, the average value can be considered as the percentage of CCA failures in (approximately) last AVERAGING_WINDOW frame transmissions.

OPENTHREAD_CONFIG_FRAME_TX_ERR_RATE_AVERAGING_WINDOW

 OPENTHREAD_CONFIG_FRAME_TX_ERR_RATE_AVERAGING_WINDOW 128

OpenThread's MAC implementation maintains the average error rate of MAC frame transmissions per neighbor.

This parameter specifies the window (in terms of number of frames/sample) over which the average error rate is maintained. Practically, the average value can be considered as the percentage of failed (no ack) MAC frame transmissions over (approximately) last AVERAGING_WINDOW frame transmission attempts to a specific neighbor.

OPENTHREAD_CONFIG_IPV6_TX_ERR_RATE_AVERAGING_WINDOW

 OPENTHREAD_CONFIG_IPV6_TX_ERR_RATE_AVERAGING_WINDOW 128

OpenThread maintains the average error rate of IPv6 messages per neighbor.

This parameter specifies the window (in terms of number of messages) over which the average error rate is maintained. Practically, the average value can be considered as the percentage of failed (no ack) messages over (approximately) last AVERAGING_WINDOW IPv6 messages sent to a specific neighbor.
