STM32F411 flow controlled serial communication with CC2530

Hello there from Germany.

I am trying to connect an CC2530 as a coprocessor to the STM32F411. The CC2530 only supports UART communication with RTS / CTS. According to the data sheet, the STM32F411 supports modem control and RTS/CTS on its UART interfaces. However, I can't call set_flow_control from an instance of mbed::Serial because of the missing preprocessing macro "DEVICE_SERIAL_FC" in the target device.h because it isn't declared. Is this maybe a bug or am I doing something wrong here?

Have a nice day,

Christian

You may be able to achieve your goal by using STM32CubeMX, and using the code in your program.

The flow control code is not implemented for the F411, which is why that macro is not set.
