How can I communicate with DA14531 module in DSPS mode with 2 wire uart?

Hi,

I want to use DSPS mode for communication and I want to use 2 wire uart. I know binary mode but I dont want use AT commands. I want the module to be in communication mode as soon as it starts. I don't want to put it into mode by sending AT commands.

  • Hi Cihan,

    Thank you for posting your question online.
    The DSPS is supported with 4-Wire UART and FlowControl.
    As you can see on the DSPS Getting Started Guide:2. Getting Started — DSPS Getting Started (renesas.com)

    Inside our CodeLess projects you saw that you can enter binary mode. The binary mode of the AT commands (CodeLess) application is a stripped-down version of the DSPS and operates at a much lower transmission rate compared to the DSPS application. To provide a sense of perspective, the UART baudrate in the AT commands binary mode is operating at 57600 baudrate while in DSPS it is configurable up to 921600 baudrate.This is the main reason you will need RTS and CTS pins connected.
    Is there a reason why you do not want to connect RTS and CTS?

    Kind Regards,
