    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,

    just adding to this..I used termite to check the UART status start....but when I connect and press green light above RTS I still did not see any message now...I wanted to know how I can configure ourselves so that we can have control over the UART code so that we can flash what we intend for.

    our requirement is UART communication from out custom board to Nordic BLE and then receiving from Nordic BLE to custom board through UART.what needs to done to acheive this..kindly guide us.

    regards

    Hi,

    If you're using nRF5SDK then SES from SEGGER is a good choice for an IDE. See our Getting Started tutorial on Segger on how to get started.
