USR IOT WH-BLE103a

The WH-BLE103 module is an ultra-low-power Bluetooth 4.2 module designed for point-to-point transparent data transmission and encrypted transmission. Users do not need to be concerned with the transmission protocol — simple configuration is all that is required to establish communication. This module supports both master and slave roles: users can pair two modules in a master-slave configuration for transparent data transmission, or develop a mobile APP based on the standard BLE protocol for connection and communication. The module supports one-to-many broadcasting; users can easily configure it as a broadcast signal transmitter, and with the built-in iBeacon protocol, it can be deployed as an iBeacon device with minimal setup. The module also supports 128-bit UUID modification, ensuring compatibility with modules from other manufacturers. It is a versatile, simple, reliable, and highly compatible IoT transmission module.
