Up to eight users or devices can form a piconet and up to ten piconets can co-exist in a single service area. The quipment
that shares a single channel can only use part of its capacity. Although the channels have a bandwidth of 1Mbit, the more
users that join the network, the more capacity is reduced, to approximately10 kbit/sec. To solve this problem, a solution
was adopted that gave rise to the concept of scatternet. The units that are in the same service radius can potentially
establish communications between themselves. But, only those units that really want to share information share a single channel, thus creating a piconet. This fact makes possible to create several piconets in overlapping service areas. A group of piconets is called a scatternet. The Android API allows us to connect to Bluetooth devices by point-to-point or multipoint connections. This API is distributed by the packet named android.bluetooth. The Android methods to handle Bluetooth communications include operations such as devices searching, identification of devices connected, socket creation for listening to other devices, instances creation for other devices management, etc.
