    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

    Hello Elfving,

    Thanks for your response. I did have a look into your tutorials..Now I have decided to go with Nrf connect SDK ...also I got some clue on UART link you have shared which I will have a deeper look..just let me know for Nrf connect SDK..I have installed nRF connect to desktop ..is this correct??.

    so the path is use nRF connect then start the basic project ..connect to Zephr libraries use BLE..then configure UART...then do the testing...is this path correct??

    Let me know..sorry trying to understand

    Thanks and regards
