maximum how many bytes of characters can i send through UART?

[vprasath]

I'm trying to send a string of 140 characters length using UART.....but only 98 characters length is being recieved in the output.

what could be the issue? How many bytes of string can i send through the UART?

Thanks,

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.
