Hi, I've had an STM32F411 development board for sometime and have done hobby projects with practically every peripheral on the board (audio output, mic, accelerometer, gyroscope, etc) programming both with and without the HAL. I'm now interested in learning more about how to use bluetooth with this board but I have no idea where to begin. I've googled some and haven't really found much basic info (i.e. how bluetooth works with an STM32F4 board, what hardware I need to buy, etc). Could someone please recommend a good starting point?
