RTT debugging: Only some prints gets printed and the rest do not.

[Faizan]

Hi, I'm using RTT debugging with soft-device "https://devzone.nordicsemi.com/tutorials/6/debugging-with-real-time-terminal/" , I'm able to print few messages, after which messages stops printing.

Does RTT debugging by default works in blocking mode ?

Thanks and Regards, Faizan

I have never experienced this. SEGGER-RTT uses non-blocking mode per default. Are you sure it is not your application that stops?

I don't know i' using default code, I just downloaded the directories from Segger and copied them in to my project, i'm using arm gcc compiler not keil

The strange thing is that it works for a while and then stops.

• When you say messages do you mean complete messages? More than just a few characters?
• Have you debugged your code to make sure it is not your application that halts?
• Are you using an example from an SDK? If so which example and which SDK?
• Do you mind sharing your code?

complete messages My code is a working code, in which i integrated RTT message in place of uart. yes i built my code on ble_hrs examples. Yes i would if it is really necessary

What SDK are you using? SDK 11 has included the RTT files and uses them in e.g. the hrs example. There are some pretty big differences in the files in the SDK and the ones linked to in the tutorial. Have you tried the files in the SDK?
