Using J-Link RTT Viewer for data transfer

pal_722

Hi, 

I am currently working on v2.8.0 peripheral_uart and central_uart samples. I want to send some n number of data from both the boards terminal to see if I have any data loss.
I want to do this in J-Link RTT viewer. Is it possible to do this on the viewer?
i know UART debugging is enabled and that we can use any serial terminals to do the same, but I have a doubt if we can do it in RTT viewer.
For example: Can I use J-Link RTT viewer as PuTTY ?



Regards
Thank you 
Pallavi

    Its possible but I see problems:

    1. RTT up buffers are tiny (host=> device direction). Can be reconfigured via KConfig/prj.conf. The default 32 bytes will likely be the limiting factor if used unchanged.
    2. RTT viewer has no convenient mass input that I can see, only the one input line. Output logging is possible.
    3. RTT messages can be silently dropped whenever you create too much input data. Depends on how the message output functions are used.

    Note that the active SWD connection for RTT can also affect the MCU behaviour especially on how the cores can sleep.
