Answer 1

Is it possible with bluetooth android API to broadcast data that was sent by one slave and the data will be received to all (master and slave) in the piconet? If it is possible, how does it works? It goes to the master first and then gives to all slave, or slave directly one by one contact another slave?

in a piconet you have one master and unto 7 active slaves, Bluetooth broadcast works form Master to all slaves - In android there are no APIs for applications to use the broadcast feature. Slaves can directly talk to only the master. It is a star topology Master talking to slaves and slaves to Master.

Can one device connect to two or more different piconet?

Yes - You can me Master in one piconet and slave in other piconet/s Or Slave/s in different piconet/s

If the master is down, can it delegates automatically to other slave?

No
