This project contains the source code of an nRF24L01+ and Blue Pill (STM32F103C8T6) based RF scanner. The Blue Pill scans frequencies from 2.400GHz to 2.525GHz (1MHz resolution) with nRF24L01+ and plots the activity on each frequency through UART.
Customizable Bootloader for STM32 microcontrollers. This project includes demonstrations for various hardware how to perform in-application-programming of a firmware located on external SD card with FAT32 file system.
