NXP Low Power Bluetooth Control Robot Reference Design
The Bluetooth® Low Energy (BLE) controlled robotic reference design was developed using the FRDM-KW40 board and the Pololu Zumo robot and can be controlled via the mobile app. The BLE-controlled robot is based on the KineTIs KW40Z System-on-Chip (SOC), which includes an ARM® Cortex® M0+ processor with a 2.4 GHz radio for BLE and 802.15.4. It is implemented using the HID over GATT configuration file and is used as a human interface device. Features provided by the software include: BLE data to mobile app transfer, motor control and battery monitoring, and more.
