    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 

    regards

    Hi Elfving,

    SO once I get windows 10 I am planning to follow these steps

    1. Install nRF connect to desktop,then install tool manager and then VS code .

    2.Once VS code is opened go to Nordic extension and install 

    3.Once nRF connect is installed you zephry root/poject should work along with kconfig 

    4.Then we need to create an application using Zephry using which BLE and UART will be called(need to explore on this

    5.Then you compile and flash the hex file to see whether this is working

    Are my points correct let me know

    For time being I have ubuntu 18.04 ...can I try with this..any luck.

    regards

    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.

    Best regards,

    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?

    Best regards,

    Elfving
