How to enable nCS printf statements on SES in debug terminal

Okay, so what board file are you using, and where do P0.06 and P0.08 go on the BL653 board (which are the default pins used by the UART). If you set the RTT console as in the peripheral UART you should be able to connect to RTT in the nRF terminal by selecting the board name instead of the COM port. I don't know what pins the BL653 uses for UART communication. You might have to make some changes in the board file (UART pins) to see UART data out on your terminal.

Best regards,

Simon

Hi Simonr,

Thanks for the info.

Coming back to my original issue:

How can i get BL653 prints on NRF TERMINAL of VSCode.?

Have attached the conf files for your reference, I am using a simple hello_world sample project.

From this prj.conf file (the peripheral_uart prj.conf) the RTT is used as a backend to print log messages, as the UART is used as a service and to print communication from the device it's connected to over BLE.

Please try downloading and using SEGGERs RTT viewer and use that while the device is connected to a debugging device. Using the UART backend to print won't work I'm afraid as that UART instance is taken by the application. I would also recommend using printk instead of printf as the CONFIG_LOG_PRINTK=y routes printk() to the log module. You can set it to =n to use the CONSOLE backend instead (see configs UART_CONSOLE and RTT_CONSOLE, and thus printf).

Best regards,

Simon

Hello Simonr,

devzone.nordicsemi.com/.../3730.prj.conf

PFA the prj.conf file for BL653 peripheral_uart project, I added printf( ) inside the main function of BL653 peripheral_uart project and I wasn't able to see the printf's on the terminal.

Can you kindly guide.?

Okay, do you know what pins the BL653 uses for UART communication over terminal? Since it is not the nRF52833 DK from Nordic I can't guarantee that it uses the same pins for UART communication with the computer. I would suggest taking a look at the prj.conf file from the peripheral_uart sample projects located at ...\ncs\v1.7.0\nrf\samples\bluetooth\peripheral_uart where a few vital configs are set to make sure prints are being printed to the UART console, and enabling the UART driver, etc.

Best regards,

Simon

Hi Simon,

I am using the BL653 dev kit for nRF52833, I am on debug mode in my screenshots so you see my CPU paused.
My prj.conf file says : "# nothing here".

Thanks,

Simonr — Wed, 03 Nov 2021 10:19:02 GMT

Can you show me the prj.conf file of your application, so I can make sure that UART is enabled correctly? Also, your screenshot shows that the debugger has the application paused, but I assume you don't see anything if you press F5 to start the CPU either? And just to be sure, can you confirm whether you're working on an nRF52833 Development Kit (PCA10100) or not?

Best regards,

Simon

Hello Simon,

I did exactly that, yet all of my printfs, printks and couts are not visible on NRF Terminal

Let me just sequentially post pics for the configuration I am doing:
1.

And no prints.

Kindly help me out.

Please note that you should press the VCOM3 > button in the CONNECTED DEVICES tab in the bottom left. Set the baud rate to 115200, no parity, 8 data bits, 1 stop bit. Flow control should be enabled.

Hi Simonr,

Even after enabling COM port, i cannot see the printfs

Can you help me on how to setup the COM3 port as in below:

After baud rate it asks me parity and stuff.

RE: How to enable nCS printf statements on SES in debug terminal

Simonr — Tue, 19 Oct 2021 07:58:15 GMT

Great, in the nRFConnect extension, at the bottom left there is a tab of connected devices where you can see your connected DK for instance. You need to choose the COM port you want to see in the NRF terminal in order for anything to show up there.

Simon

Hi Simonr,

I do have the nRF Terminal installed

But yet I do not see any printf's or printk's on the terminal.

I assume you use the nRFConnect extension pack for VS code, correct? If you also instal the nRF Terminal extension you get a serial terminal called NRF TERMINAL in the Terminal panel. You can connect to your device over serial port (UART) or RTT.

Hi Simonr,

Thanks for the info, kindly guide me how I can get printf and printk statements to be visible on VSCode..?

RE: How to enable nCS printf statements on SES in debug terminal

I assume this is the NCS_version\zephyr\samples\hello_world you're referring to?

I think this is because the Hello World message is printed over the UART backend instead of the RTT backend (which the SEGGER debugger uses). You can try setting the CONFIG_LOG_BACKEND_RTT to 1. See more on that in the logging user guide here.

Best regards,

Simon
