General description
The BX2416 is an ultra-low-power system on-chip(SoC), a Bluetooth chipset, integrated with 32-bit MCU for Bluetooth 5.0 low energy(BLE 5.0) applications which shows the great performance of a leading RF transceiver with low-power consumption. It meets the challenges of a broad range of applications that need advanced Bluetooth LE features.
Also Bluetooth mesh can be run concurrently with Bluetooth LE, enabling smartphones to configure and control mesh nodes.
