Sid_end_device cannot use rtt

[666]

Hi All,

1. The SDK used in VS code is version 2.6.1, and running the periphral_uart demo can print in rtt, but not in sid_end_device

The official routine is used for sid_end_device, and no modifications have been made to the code. As we need to use rtt, we will modify the prj.conf

# Log

CONFIG_LOG=y

CONFIG_LOG_PRINTK=y

CONFIG_LOG_BUFFER_SIZE=2048

CONFIG_NVS_LOG_LEVEL_WRN=y

Change to

CONFIG_LOG=y

CONFIG_USE_SEGGER_RTT=y

CONFIG_LOG_BACKEND_RTT=y

CONFIG_LOG_BACKEND_UART=n

CONFIG_LOG_PRINTK=n

However, there was no response during operation

2. Also, I would like to ask if the demo of sid_end_devicedefaults to UART, but I couldn't find the configuration for this UART, so I don't know which IO port UART is printed on for output.

note:Using NRF52840 SOC

Looking forward to seeing you on our platform.

Thanks,

Hi

1. As sid_end_device has a lot of configuration options depending on the config you select, could you elaborate which config you have selected? 

2. I would presume it uses uart as default since you already would be using uart for the command line interface. Normally uart0 is the default uart and you can see the default pins here and here

For the default demo, only two changes were made. The first one, prj.conf as mentioned in the question, and the second one, as shown in the above figure, only moved the board target, selecting nrf52840d_nrf52840 and selecting Nordic Soc, without moving anything else

I added it through

&qspi {

status = "disabled";

};

and

CONFIG_MAIN_STACK_SIZE=2048

Solved the above errors

But new problems have arisen,

This is done through debugging in sid_init (&sm ->sid ->config,&sm ->sid ->handle); After calling, it died without any modifications to the code section, using the default code of the demo

Looking forward to your reply

Hi,

Runar is currently out of the office.

Have you done everything mentioned in setting up your Sidewalk device? 

 Which sample_variant do you use?

Best regards,

Already completed;

Using the default overlay-hello

After testing, if using nrf52840dk, it will also work like this, but pressing the reset button again will make it normal

But if a customized board is used, what can be used instead of this reset button

Hi,

Can you provide more information about your custom board?

Best regards,
Dejan

Hi,

You could try to reset your device using nrfjprog options which reset the board. For example, you could try to reset your device using nrfjprog --hardreset, nrfjprog --reset or nrfjprog --debugreset.

Best regards,
Dejan
