I need a small GUI app for STM32F746 Discovery that will send a message on USART when a button is pressed. The application will also have to receive messages on the same USART and display them on screen. The application must be developed in MDK 5.25. The HW sender/receiver is an XBEE S2B.
I am having 5+ experience in embedded firmware development.. I am expertise in the Bluetooth low energy. I have worked on the nrf51 nrf52 TI ST controller...
