using two UART in nRF52833

[lyrics]

Hi,

I use 9600 bsp of UART to communicate sensor data. I would like to add 115200 uart for wifi.

To use two uarts at the same time, what configuration should I do and how should I initialize? (It is impossible to initialize uart twice..)

Other than that, what are some good examples to refer to for using two uarts?

Hi,

Which software development platform are you using, the nRF Connect SDK or the nRF 5 SDK?

I use nRF 5 SDK!

Hey,

My apologies for the delayed response. You could refer the example  Serial Port Library Example with two UARTEs. Note that this example is removed in SDK 17.0.0. In nRF5SDK v17.0.0 and later, it is recommended to use libUARTE. Kindly take a look at this ticket for an example.

Kind Regards,

Swathy

Hey,

Sorry I forgot to add the Devzone ticket to refer for the example based on libuarte in the previous reply. You can find it here. Libuarte is an advanced UARTE library that improves the flexibility of UARTE usage and is considered more reliable. It uses 2 timers and PPI. You can read more about Libuarte and serial UART from the links provided. The nrf_serial library was removed in SDK 17.0.0 onwards.
