I am trying to send some data from RPi , And I am using the example of NRf Uart APP.
printf("\r\nUART example started.\r\n");
while (true)
{
uint8_t cr;
// printf(" \r\n entering loop!\r\n");
//app_uart_flush();
while (app_uart_get(&cr) != NRF_SUCCESS);
{ //printf(" \r\n Not recieving \r\n");
}
// if(cr!=NULL)
// printf(" \r\n received data %d!\r\n",(int)cr);
// while (app_uart_put(cr) != NRF_SUCCESS);
app_uart_flush();
// printf(" \n %s \n",cr);
if (cr == 'q' || cr == 'Q')
{
printf(" \r\nExit!\r\n");
while (true)
{
// Do nothing.
}
This is the section i am having difficulty understanding
I am sharing the output screen also.
As you can see what i expect as an outout and what i get.
Please help.
Right window is an Rpi window via putty and the left window is a tera term debug terminal
I have tried changing clock speeds,that doesn't help.
I have verified TX and RX pins and jumber wires are fine.I am not using CTS and RTS pins
I have connected RPi to a USB TTL converter and i was able to receive the data.
