Is nRF52 will work with 115200 without any issues?

Hi,

I am working with ble_app_uart code, in that I am trying to configure different baud rates like 9600,38400 and 57600. With these baud rates I am not getting any issues with the data transfer. But with 115200 device gets reset continuously I can't send the data with 115200. First of all I want to make sure that nRF52 will work fine with 115200.

Consider I will be sending continuous stream of data. Same data with other baud rates are working fine but I am facing problem with 115200.

Waiting for quick reply.

But with 115200 device gets reset continuously

Smells like a problem in your code. Obviously, higher baud rates are more likely to trigger bugs.

I can run my NRF52 with 460800 baud and no problems.

Note that you must use hardware flow control with high baud rates like 115200, especially if you used a softdevice. Otherwise you will highly likely get FIFO overruns in the UART, as the softdevice can block interrupts for radio activity.

Without adding my logic also board is getting resets. Also enabled Hardware flow control. So I am assuming that there won't be any mistake in code.

Are you sending continuous data in 460800?

Hi,

A reset indicates that you are running into the error handler, where the default behavior is to do a reset. You should then debug in order to find the reason for the reset. See this post about debugging.
