New: BLE module BLE5201 adopts Silabs core chip & BLE 5.2 protocol

By sdga:NiceRF Wireless Technology Co., Ltd

In May 2021, NiceRF launched new BLE module BLE5201. It adopts BLE 5.2 protocol and Silicon Labs' EFR32BG22C224 SOC chip.

BLE module BLE5201 adopts Silabs core chip & BLE 5.2 protocol


Introduction of BLE module BLE5201

BLE5201 has low transmitting and receiving current (3.6 mA when transmitting power is 0 dBm; receiving 2.6 mA) and 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. BLE module BLE5201 supports applications that require direction finding or low energy Bluetooth Mesh nodes.


Features of BLE module BLE5201
