BLE radio frequency module
Radio modules for Bluetooth Low Energy( BLE) are small compact plug-in cards or components.
BLE radio modules are used in smart homes, industry, and smart wearables, among other applications; they process the received sensor data and radio it to a Bluetooth station or smartphone via the Bluetooth network. BLE radio modules can be implemented as miniaturized modules as a system on chip( SoC). They contain a microcontroller that processes and stores the data collected by microsensors and transmits it to the smartphone via the radio interface. The firmware can also be updated via this radio interface and updates and new functions can be transferred.
