Hello,
Im using custom board carring nrf52820,and i want enable UART to contact with another mcu,this is the Schematic.
NCS V2.6.0.I take Peripherial_uart to Peripherial_hid_keyboard,and it can work in nrf52833DK,but can't in my custom board.
it contants RX,TX,CTS and RTS,and i think my configuration is matched.But cannot rec data sent from UART via PC like this.
and my prj.conf is here.I am not sure where the question is.Can u help pls?
