Hello,
I am trying to communicate urart with nrf52840 and other devices.
But there was a problem. You can transfer data from the nrf52840 to another device, but if you transfer data to the nrf52840 from another device, it will not be received from the nrf52840.
The pins are connected properly, and HW_FLOW is being used, and CTS and RTS are also connected.
Why can not I receive data from nrf52840? When I checked the other device TX pin with the program Logic, I confirmed that the output is normal. But what's wrong, nrf52840 is not receiving rx.
"app_uart_get (& recv_data)" to output data when it comes in, but it is not printing.
I'm not using 'app_uart.c', but I'm using 'app_uart_fifo.c'.
Can you help me?
