The low-power Bluetooth microcontroller chip integrates a BLE radio transceiver, memory, CPU, and related peripherals into a single chip, forming a microcontroller capable of transmitting and receiving Bluetooth radio signals. The low-power Bluetooth microcontroller chip adopts a wireless connection method, enabling it to quickly access smart terminals such as mobile phones, tablets, and televisions, enabling data sharing and intelligent control. The company's low-power Bluetooth microcontroller chips are mainly used in smart home, wearable devices, and other fields. 1. Receive wireless Bluetooth signals from the Bluetooth RF antenna port, store the data in memory, and then process it by the central processor to trigger corresponding peripheral actions. 2. After the peripheral detects an external event, the central processor prepares the data in memory and sends wireless Bluetooth signals through the Bluetooth RF antenna port. 3. Receive and send wireless Bluetooth signals through the Bluetooth RF antenna port according to the agreed periodic time.
