https://devzone.nordicsemi.com/f/nordic-q-a/111876/nrf52840dongle-cannot-output-logs-using-uartI use the nrf_dm demo program, when using the nRF52840DK development board, the program can print the log normally. Then I changed the build configuration to nRF52840Dongle. After compiling and downloading dongle, the firmware can run normally, buten-USTelligent Community 13Sat, 15 Jun 2024 14:21:09 GMThttps://devzone.nordicsemi.com/thread/488948?ContentTypeID=1Sat, 15 Jun 2024 14:21:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c3de2b7f-cc6d-4cd0-9535-56b158f59a0bJune11<p>Hi,</p> <p>I suddenly understand that I should not use UART to receive logs, it is through the USB output log.</p> <p>DK Board&nbsp;can use UART output, which is a bit misleading.</p> <p>The problem has been solved, thank you.</p> <p><span>Best regards</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/488947?ContentTypeID=1Sat, 15 Jun 2024 14:07:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4277e379-34bd-4ac3-a40b-0fb447a279b3June11<p><span>Hi</span></p> <p>I used the sscom serial tool to view the dongle logs.

How are you opening the terminal on your end when trying to log from the Dongle?</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
