nrf52832 UART baudrate

[H-ogawa]

Hi,

When using uart with the nrf52832,do I need to use  hardware flow control for comunications over 9600bps?

Hello Hiroki,

Documentation on packet loss for different BAUDRATES?
Packet loss/corruption on an UART connection is often most caused by the software running on the receiving unit not being able to handle the incoming data quickly enough. This ticket might be helpful to see. So, unless a whole lot is happening on your nRF52832 at the same time, you should be completely fine on 115200 BAUD. Hardware flow control negates this problem by only getting data when it is acceptable.

Have you observed any packet loss or data corruption on your current UART connection?

Of course, you might have external disturbances on your communication lines if they are long, uninsulated and close to a noise source with relevant frequencies, but I suspect this is not what you were asking for originally.

Hope this is what you were looking for. If it was not, please let me know.

Best regards,
Karl
