using two UART in nRF52833https://devzone.nordicsemi.com/f/nordic-q-a/83220/using-two-uart-in-nrf52833Hi, 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..)

You can find it <a href="https://devzone.nordicsemi.com/f/nordic-q-a/77956/libuarte-instead-of-serial-uartes/322286#322286">here</a>. Libuarte is an advanced UARTE library that improves the flexibility of UARTE usage and is considered more reliable. It uses&nbsp;2 timers and PPI. You can read more about <a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_nrf5_v16.0.0%2Flib_libuarte.html">Libuarte </a>and <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/lib_serial.html?resultof=%22%73%65%72%69%61%6c%22%20%22%70%6f%72%74%22%20%22%6c%69%62%72%61%72%79%22%20%22%6c%69%62%72%61%72%69%22%20">serial UART</a> from the links provided.
