That's great 🙂

If you can spare the time, it would be benefit to other users if you could explain what was exactly causing it.

So did you get to the root of the problem?

do another thing, remove wait_for_fds_ready() and put a delay of 300ms for example

manoj97 — Mon, 20 Jan 2020 10:03:27 GMT

yes i made to 0 no change in output

Ameer Usman — Mon, 20 Jan 2020 09:57:38 GMT

in sdk_config.h set this:

#define NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED 0

Also you are using the fds example or a custom code?

manoj97 — Mon, 20 Jan 2020 09:51:35 GMT

yes i done that

see i defined a read and write function in .c file and included its header in .h file

i called those functions after the "wait_for_fds_ready();" and before "cli_start();"

then i start debuging i'm getting blank screen on putty

Did you enable fds_register before initializing?

fds_register(fds_evt_handler);  //Register event handler of FDS and will show notifications on log, not required for production
rc = fds_init();                //Initializing FDS
APP_ERROR_CHECK(rc);

Ameer Usman — Mon, 20 Jan 2020 08:48:17 GMT

Ok I want to get one thing clear, you are not getting any messages or just the messages from the FDS?

Also are you using Development Kit or another board? There should be the logging being viewed in the Segger in debug mode when using J-Link.

Also for simplicity, please use this Serial Terminal:

Have you turned on printing in the sdk_config.h file?:

#define NRF_LOG_ENABLED 1

#define NRF_LOG_BACKEND_RTT_ENABLED 1

Also are you using development kit?
