Read full description

A simple application to demonstrate Firmware Over-The-Air (FOTA) for onsemi RSL10/RSL15 Bluetooth Low Energy devices. RSL10 and RSL15 are ultra-low power Bluetooth Low Energy wireless microcontrollers from onsemi. The FOTA application acts as a central device to scan, connect and transmit the firmware image to a remote RSL10 or RSL15 device. The remote device firmware must have FOTA-enabled firmware to receive the FOTA firmware image. For more information, visit the RSL10 and RSL15 webpage on https://www.onsemi.com. For support, visit the onsemi Community Forum at https://www.onsemi.com/forum/. Note: - RSL FOTA application requires Bluetooth Low Energy feature to be enabled to scan for Bluetooth Low Energy devices.
