Thingy53 server doesn't show LOGs

[simon8]

Hi,

i'm trying to creating a project where my thingy53 is a coap_server thread node that sends environmental data to a coap_clinet (nRF5340).

The problem i found is that, even if i enable LOGs, none of them is shown on the nrf terminal, only works printk(), but not in the main function.

i thought the roblem was correalted to USB CDC ACM that i enabled following the peripheral_uart sample... i don't know if i followed the right procedure, i only compy and pasted overlay files and config commands.

How could i fix these problems? is the correct way to enamble the MTD mode in my thingy?

this is the project:

thingy_coap_rec_myserver.zip

thanks a lot

simon

Hi, 

Are you using NCSv2.1.0? If so, you can refer to https://github.com/nrfconnect/sdk-nrf/blob/v2.1.0/samples/openthread/coap_server/overlay-logging.conf and https://github.com/nrfconnect/sdk-nrf/blob/v2.1.0/samples/openthread/coap_server/overlay-rtt.conf 

Seems it's missing CONFIG_SHELL_LOG_BACKEND=n.  

Regards,
Amanda H

I tryied that but nothing cahnged...

so i tryied this:

# Config logger

CONFIG_LOG=y

CONFIG_USE_SEGGER_RTT=n

CONFIG_LOG_BACKEND_RTT=n

CONFIG_LOG_BACKEND_UART=y

CONFIG_SHELL_LOG_BACKEND=y

CONFIG_NET_LOG=y

CONFIG_NET_CONFIG_LOG_LEVEL_INF=y

and this is what it prints out:

Seems CONFIG_LOG2_MODE_DEFERRED=y is deprecated in v2.1.2. Try CONFIG_LOG_MODE_DEFERRED=y.

even with that, nothing change...

i tried to add these line of code, took by the file thingy53_nrf5340_cpuapp.conf  in the boards folder of the peripheral_uart sample:

# Config logger

CONFIG_LOG=y

CONFIG_USE_SEGGER_RTT=n

CONFIG_LOG_BACKEND_RTT=n

CONFIG_LOG_BACKEND_UART=y

CONFIG_SHELL_LOG_BACKEND=y

CONFIG_NET_LOG=y

CONFIG_NET_CONFIG_LOG_LEVEL_INF=y

CONFIG_LOG_MODE_DEFERRED=y

CONFIG_LOG_PRINTK=y

CONFIG_LOG_PROCESS_THREAD_STACK_SIZE=1024

CONFIG_LOG_PROCESS_THREAD_STARTUP_DELAY_MS=4000

and logs looks better:
