There isn't a "faster" way to restart communication. For the slaves, once the link is disconnected, there should be
a function callback of which it will start to advertise (low-duty) again. However since the slave has already know
the Master's BD address, it can exert the below:
For the master, once it recovers, it can exert scanning:
Thanks btta. I have a followup question to your original answer "For the slaves, once the link is disconnected, there should be
a function callback of which it will start to advertise (low-duty) again."
Can you give me rough estimate of the time duration of when a piconet of 4 devices stops working (after the master shuts down) and a new piconet of the remaining 3 devices can reform and start communicating again?
Is it likely more than 0.1 second?
In my reply above, I assumed that it's a slave that has been shut down. When the slave wakes again, master can discover and connect to it. However if it is the master breaks down, then the whole piconet breaks down. A new star-network may not be formed unless one of the remaining three takes the initiative to be the new master. Even then, the whole discover_and_pairing cycle has to start again and it is not possible to estimate how fast it can be completed.
