The demo shows the Dual-Mode capability of the KW40 Wireless SoC: BLE + 802.15.4. FRDM-KW40Z is connected via BLE to handle device that is measuring heart rate through NXP Smartphone app that implements Bluetooth Smart Heart rate profile. At the same time KW40 is connected via 802.15.4 to an end device running on FRDM-KW24Z512 (the 802.15.4 packets are sniffed by USB-KW24D512 dongle along with a Protocol Analyser app running on Windows tablet that is used for the Energy meter/Earthquake demo).

Value Propositions

 

NXP KW40Z is an ultra-low-power, highly integrated single-chip device that enables Bluetooth® Smart/Bluetooth® Low Energy (BLE) v4.1 and/or IEEE® 802.15.4-2011 RF connectivity for portable, extremely low-power and secure embedded systems.

The KW40Z MCU offers Dual PAN Support which allows the system to concurrently participate in two 802.15.4 networks, such as Thread and ZigBee® or an 802.15.4 based network and BLE, eliminating the need for multiple radios, reducing system complexity and ultimately cost.

The KW40Z MCU integrates a buck-boost DC/DC converter, supporting a wide range of operating voltages from 0.9 V to 4.2 V, which significantly reduces the peak current in receive mode down to 6.5 mA and transmit down to 8.4 mA.
