Console Read Issue

[Aditya Xavier]

Hi Mynewt Team,

Am facing issues with console_read API.

I have a MCU sending CBOR data to nRF over UART.

Console_read works perfect when receiving data from USB->Serial adapter 
(Computer) & RTT.

Console_read give multiple hits ( i.e. multiple times it would reach either 
/*Got Full line - break …*/ or /*Do some work…*/

How do I fix such a situation.

Thanks,
Aditya Xavier.

    int rc; 
    int full_line;

    off = 0;
    while (1) {
        rc = console_read(buf + off, MAX_INPUT - off, &full_line);
        if (rc <= 0 && !full_line) {
            continue;
        }
        off += rc;
