some times receive error data(for eg :- pressing A shows other character )

when i test nrf 52 DK no missing or error data (works fine)

i need some help

Hi Alan.

The nRF52840 Dongle is meant to be used with nRF Connect to test your nRF-based wireless soultions, not to develop on.
Example applications which works with the Dongle is found under the board name pca10059. It is possible for you to develop your own applications, but this requires a fair amount of modifications, so I would not recommend that you develop on the nRF52840 Dongle.

You should develop using the nRF52840 DK.

When it comes to your question, this could be a result of the modifications that are required. It could be either wrong baudrate or flowcontroll.

Thanks for your replay,

I tested changing baudrate(115200 and 56700) and disable flow control the result has same

some times its work fine and some times its show error

Hi Alan.

As I said, developing on the nRF52840 Dongle could require a fair amount of modifications in the code, so I highly recommend that you develop on the nRF52840 DK.

The results of the application you try to run may work something, and may not work other times. This is because we have not yet added full support in the SDK, if you use this as a development kit at this point its on your own risk.
