UART maximum Baud rate

[Chiaq]

Good morning,

I need to use the UART peripheral to send a stream of data from the computer to the nRF52832 development kit.

For this reason I need to maximize the rate at which these data are sent. I saw that the maximum baud rate of UART is 1M, but I was wondering if this 1M is bytes per second or bits per second.

My goal is to send these data at 1.28 M bits per seconds (160 k Bytes per seconds), would that be possible with the UART? If not, the UARTE would make it possible?

Best Regards,

Chiara

Both UART and UARTE max out a 1 MBit/s.

If you wanted to exceed that with a PC connection, use the NRF52840 with its USB peripherial.

Thank you for your reply.

What about using the nrf52840 dongle, I know it doesn't have UART. But is there a way I can use higher baudrate to transfer data to the computer?

Hello Chiara,

As Turbo suggests you would have to look at using the USB peripheral instead, if you intend to use a baudrate higher than what is available over UART.
If you are working with the nRF52840 Dongle it might be useful for you to have a look at this nRF52840 Dongle programming blogpost by my colleauge.

Best regards,
