Introduction

BLE5201 Bluetooth data transmission module uses Bluetooth 5.2 protocol and EFR32BG22C224 SOC chip. It has the characteristics of low power consumption, small size, long transmission distance, and strong anti - interference ability. It has ultra - low transmit and receive current, high - performance, low - power M33 core, which can extend the life of button batteries to ten years. Target applications include Bluetooth Mesh low - power nodes, smart door locks, personal healthcare and fitness equipment. The SOC’s Bluetooth Angle of Arrival (AoA) and Angle of Departure (AoD) functions and positioning accuracy within 1 meter will also benefit applications such as asset tracking tags, beacons, and indoor navigation. EFR32BG22C224 SOC provides IQ sampling capability, suitable for direction finding applications, and supports 125 KB and 500 KB Bluetooth Low Energy Coded PHY, which can increase the receiving sensitivity to - 106 dBm. Supports applications that require direction finding or low energy Bluetooth Mesh nodes. The BLE5201 Bluetooth data transmission module is produced and tested strictly using lead - free technology, and meets RoHS and Reach standards.
