The problem was that the function app_uart_flush() was called before it was finished sending the TX buffer. app_uart_flush() is used to clear the buffer (to make space for something more important). Clearing the buffer does not mean sending it, but "deleting" it.

See the response that I sent you. If that works, I will post it here, so that other people with the same issue can see the solution.

Would it be possible to send the project that replicates this error, and I can take a look?

My RX and TX buffer size is 256 and my baudrate is 9600.

i can send more characters when i'm not using app_uart_flush(),but when i use app_uart_flush() it is not sending more than 94 characters.

why it is happenning ?what could be reason?how do i send more characters even when i use app_uart_flush()?

If the buffer can keep up, there shouldn't really be an issue. What baudrate are you using, and what is your buffer size?
