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 Ravi

Yes, those steps sounds about right. It does also work on Ubuntu though, however the installation process is a bit more complicated.

Sounds to me that getting Windows 10 running would be best.

Hi Elfving,

Kindly let me know how do we move on from here to get the UART with Bluetooth up and running.

As pointed out from my earlier mail..I need to go through the nRF connect and Zphery project to move on.

so your valuable inputs from here will be helpful.

Thanks and regards

Hello Ravi,

That is odd. Did you install an NCS version from the Toolchain Manager? Could you install nRF Commandline tools as well?

Hi Elfving,

Tool manager which is installed

Connect SDK V.1.7.0 ver

Open VS 

Here I am seeing could not find Zephyr root..

Below is the invalid ncs installation error

ANy idea where to debug

Let me know what could be the next debug procedure.

Thanks
