Thanks for sharing the reference material, I'd have a look into it.

Yes.

[quote userid="6462" url="~/f/nordic-q-a/75946/disable-rtt-logs-and-enable-logs-over-uart/313339#313339"]you have done a full rebuild?[/quote]

Yes.

Haven't been able to switch logs from RTT to UART tho.

AIUI, it's a telnet session

You'd have to go to Segger for details & support - it's nothing to do with Nordic.

As to your suggestion, I have all those flags enabled, but no success. I still get data on RTT.

It may be a little off topic, but can you guide, if possible, on how to access RTT via Python. Because my requirement at this point is to get the script run with the data.

Any references you can share would be much appreciated.

Thanks.

You should also be able to access the RTT stuff via Python - I think it's basically just a Telnet session? Segger have some stuff on it...

The settings are in the sdk_config.h

NRF_LOG_BACKEND_RTT_ENABLED or NRF_LOG_BACKEND_RTT_ENABLED

to use the UART, you may also need NRFX_UARTE_ENABLED and/or NRFX_UART_ENABLED and/or UART_ENABLED
