help
|
|
Use CSMA-CA mechanism (listen-before-talk with exponential backoff)
|
|
to transmit packets. This is the most common way of mediating radio
|
|
channel access and fits most usage scenarios (see IEEE 802.15.4-2020,
|
|
sections 6.2.5.1 and 10.2.8).

bool "IEEE 802.15.4 Aloha medium access protocol (CCA mode 4)"
|
|
help
|
|
Use Aloha mechanism (send without any clear channel assessment) to
|
|
transmit packets. This is a simplistic way of transmitting packets
|
|
and fits low duty-cycle contexts where the radio spectrum is not
|
|
too heavily loaded (see IEEE 802.15.4-2020, section 10.2.8). The
|
|
current implementation does not randomize channel access.
