Introduction of Low Energy Serial Bluetooth Modules

USR-BLE101 is an ultra-low power V4.1 bluetooth module. It is based on tiny packaging of 10mm x 10mm, thus, it is easier to embed into user’s device. The module is used for point-to-point data transparent transmission. User’device can communicate immediately after simple setup without concerning about transport protocol. The module supports master and slave mode. User not only can use both master and salve for transparent transmission, also can develop APP on the basis of standard BLE protocol. The module supports one-to-many broadcast, and has built-in iBeacon protocol. User can make it an iBeacon equipment with simple setup.
