SAADC project on SDK 15.0.0 Not logging correctly

[tommy.lane]

Unable to get logging information for SAADC example project in SDK versions 15.0.0, and 15.1.0.

I have no problems accessing the logs for the ble_uart_app example project.

I am developing this with Keil, and using SEGGER rtt viewer to access the logs.

Has anyone else experienced this problem, and does anyone have a solution, or work around to get data out of the SAADC project?

Hi,

Have you modified the project to enable RTT backend for the logger in sdk_config.h?

#define NRF_LOG_BACKEND_RTT_ENABLED 1

The example only have UART backend enabled by default.

Best regards,
Jørgen

Yes, Thank you, that worked.

However, you mentioned the UART backend was enabled by default and I also haven't been able to get the UART to work.
After flashing over the hex file I open PuTTY and attempt to connect to the device. PuTTY connects, but I don't get any data out.

Any ideas on that?

Which board did you test this on? Did you modify the example in any way?

I tested the example on a nRF52840 DK (PCA10056) with Putty, and I'm seeing logs as expected.

I am using nRF52832 (PCA10040) for this.
After changing the rtt backend to what it was the example is in it's default state.

Do you not see any output in Putty? Which settings are you using for the serial communication in Putty? Have you tested with another terminal software? You can also test with a frsh unzipped version of the SDK to make sure there is no other changes.
