UART OF CALENDER EXAMPLE NOT WORKING IN CLONE NRF52840.

[Sami Ul Haq]

Hey Everybody, I hope you guys find this Question in good health. I have a problem with #calender_example. When I run the Calendar example on original development kit, the UART is working fine. But when I run the same example on a clone development kit, the example did not show any error but the UART is not working and i didn't see any output on Putty. I do not know what is the problem.
Any help regarding this will be highly appreciated.
Thanks and Regards.

Hello Sami Ul Haq,

When I run the Calendar example on original development kit, the UART is working fine. But when I run the same example on a clone development kit, the example did not show any error but the UART is not working

Please elaborate what you mean when you say 'clone development kit' - is this a third-party module with a Nordic SoC on it? If so, which module is this?
If so, I suspect that the issue here is that the routing of the UART output is different on the module you are working with, so you should check its user-guide or datasheet to see if it outputs the UART on the same pins as on the nRF52840 DK.

Best regards,
Karl
