Figure 2
Master notification.
In order to avoid message collision, if a master notification is received (from another
device) no later than 100 ms after sending a master notification, the device switches to
the
“
undefined
” state and it will start the role selection process (see section 2.3).
2.2.1.2
SLAVE NOTIFICATION RECEPTION
The master expects to receive periodically (through the slave notification object) a
confirmation that the slave device is operating properly. If it doesn
’t receive
any value
through this object during
two times and a half
the slave notification time (set by
parameter), the
‘missing slave’ LED indicator will turn on. And once
any value
is
received through the communication object, the LED will turn off.
