customize board with nRF52840 needed to communicate via PC bluetooth

[Zero.cool]

Hi All,

I am working on customized board using nRF52840 chip, I have a application which was developed using nRF development kit that communicates to my customize board.

But Right now I am not able to use the development kit and I have pc and my customized board.

So using PC's bluetooth is there any application there from nordic so that I can communicate to my board.

On board I have several peripheral I need to check.

so is it possible ?

Take a look at the uart example from sdk 15. If you want to experiment with BLE UART, you can take a look at this example.

The dongle is not meant to be used as a development kit. It is a better idea to develop on a dev kit. There are a few examples in sdk 15 (just search for pca10059 under the examples folder). nRF Connect for PC will automatically program the chip using it's own connectivity firmware & be able to connect to other dev kits over ble uart for example.

Thanks for example,

But When I try to compile code via keil ( IDE I am using, with arm or GCC compiler selection).The example throws many errors, (i have tried with uart example folders, are, pca10040,pca 10040e, pca 10056) and doesn't compile.

I understood about dongle, and will not flash anything and will use by nrf go studio. :-)

Thanks,

What error codes are you receiving when you compile via Keil?

This errors I am getting while compiling using arm compiler updated version 5.
