logging in modules with RTT

Hi,

Have a look at __LOG_INIT() function in the example's main.c file. List each module as from where the logging needs to be printed as a first argument to this function(See in log.h under LOG_SOURCES). Second argument controls the verbosity of the logs. All the messages to be printed must be logged using __LOG() API.

Also, which modules and drivers are you talking about here? Modules of the Mesh SDK? If it is modules of the mesh SDK, then you should update __LOG_INIT as I mentioned above.

No not working.

The logging infrastructure is extremely complicated and in my opinion overengineered. Probably it is all very flexible, but not without a manual.

Many defines are preprocessor symbols, dozens of other options can be set in sdk_config.h.

I try to understand the logic behind it.

For example, I found following defines in the sources: NRF_LOG_LEVEL, NRF_LOG_DEFAULT_LEVEL, NRF_LOG_FILTER, NRF_LOG_ENABLED, NRF_LOG_BACKEND_RTT_ENABLED, ....

I tried also several preprocessor defines:

-DNRF_MESH_LOG_ENABLE=NRF_LOG_USES_RTT
-DNRF_LOG_USES_RTT=1
-DLOG_ENABLE_RTT=1
-DLOG_LEVEL_DEFAULT=4
-DLOG_ENABLE_RTT=1
-DNRF52_SERIES
-DPROV_DEBUG_MODE
-DLOG_SRC_PROV=1

and this goes on and on ...

Several options has relations with each other, some of them mutually exclusive, ...

Without a descent description of all of this, it is very hard to understand.

An example project where all logging is enabled via RTT, could also help.

Can you try adding NRF_MESH_LOG_ENABLE=NRF_LOG_USES_RTT to your preprocessor symbols?

Like I mentioned in my first post; this was already done, you can see that in the diff I added.

It must be something else.

Can you try using the CMSIS Configuration Wizard? Right-Click on sdk_config.h -> CMSIS Configuration Wizard. Go to nRF Drivers and choose which drivers you want to enable. Extend the folder and enable logging for that driver.

To enable in the wizard check of the box, see picture below:

Hello,

yes, RTT is logging on my project, but only for messages which I log in my application with _LOG.

My question was how the modules and drivers can be configured to do logging via RTT.

Hi,

RTT logging should already be enabled by default. Have a look at this.
