[Bluez-users] bluez scatternet

[N. I.]

I'm new to Bluetooth, as well as scatternet type of network.

I'm trying to create a scatternet network as followed:

Piconet 1:
Master A
Slave B, C, D

Piconet 2:
Master C (slave in piconet 1)
Slave M, N, Q.

My questions:

1) What are the steps to create this type of scatternet?
  What should be done to configure master/slave C to play this role
in the network?

2) Assuming that the scatternet is created succesfully. If
Master/Slave C dies, how can slaves M, N and Q be able to route
messages to Master A?

3) For this current configuration of network, what should I consider
in pairing devices in sunny situation (Master/Slave C up and running)
and when master/slave C dies (rainy condition)?

Please help,

Thanks

N.I.

create ACL links from A to B, C and D. Then use C and create ACL links
to M, N, Q.

They can't. If Master/Slave C dies, the piconet with M, N, Q dies also.
Remember that the hopping sequence of the master defines the piconet. No
master means no piconet and in your case no scatternet anymore.

I have no idea what you are talking about and what the weather has to do
with it ;)
