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,

    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
