How to use multiple serial communication on nrf52832(SDK15)?https://devzone.nordicsemi.com/f/nordic-q-a/35769/how-to-use-multiple-serial-communication-on-nrf52832-sdk15Hello. Is it possible to use multiple serial communication on 52832? What i mean, first serial port uses for communication with custom board&#39; micom chip. The second serial port uses for debugging that connected with PC.
