Hi,

Start with our lp-UART example in NCS or UART example in nRF5SDK. Documentation for the peripheral can be found here,

Hi,

Thanks for your reply.I tried unboxing the Dk kit with pulsating example which was preinstalled ..I was able to control the LED's.after this I copied J-Link OB-SAM3U128-V2-NordicSemi 170724.bin to check for the flashing LED example.

Now I cannot go back to previous one.

what I need to know is should I install Segger Embedded studio to run the IDE....I need to know which IDE  I can install so that I can run the examples by flashing.

IDE where I can code (pre installed code if any), compile and run ..similar to an IDE.Kindly let me know

Like this if I already have UART example I shall modify the same and flash the hex file.Kindly guide me

Hey again Ravi,

This is a bit strange.

In the Toolchain Manager, could you open the drop-down menu from the NCS version you installed, and then open Bash? The bash terminal might then instruct you with this:

NCS repositories are not yet cloned here. To do so run the following command:

ncsmgr init-ncs

If so, run ncsmgr init-ncs

Hi Elfving,

I did open the toolmanager ..open SDK environments...then I open command prompt....then I ran the cmd...

'ncsmgr' is not recognized as an internal or external command,
operable program or batch file.

I got this result...

what needs to be done to get this done??

Try bash, not cmd.
