Hi community member,

Please let me confirm the following question.

[Question]

 Can CC2640 support the UART with hardware flow control for communicate with external device?

If yes, could you please provide the sample code for this?

Best regards.

    Hi Kaka,

    The UART module does not support HW flow control, and this is not supported in the current SW driver either. If you need it, you need to make your own SW implementation.

    Cheers,

    A correction here:

    UART flow control is supported in HW and we have a driver supporting it in TI RTOS 2.13.00.06.

    It is enabled by configuring pins for RTS and CTS in the board file. Instructions for how to port to the latest TI RTOS is found on the front page of the Bluetooth Low Energy forum.
