There are two types of devices involved in BLE communication: peripheral devices and central... devices: Usually phones. Central devices connect to peripheral devices. BleManager type in both B4A and B4i is an implementation of the central mode. iBLE v2.00 includes a new type named PeripheralManager... as a peripheral device allows other Android and iOS devices to directly connect to it. Unlike class Bluetooth, BLE is not designed for streaming data. The throughput is quite low. About 300 bytes per second based...
