General Description
BDE-BLEM215 is a Bluetooth 4 and 5 single-mode compliant Bluetooth low energy module
targeted at low power sensors and PC/Phone accessories.
BDE-BLEM215 highly integrates Bluetooth Low Energy radio, stack, profile and applications in a
SoC, without the need of using an external MCU. The module also offers flexible hardware
interfaces for the sensor application. It supports 2 Mbps and PHY-coded which are the new added features from
BT5.2.
It enables ultra-low power connectivity and data transfer for the applications that are sensitive to power
consumption, size and cost.
