    Hey Ravi,

    which file or .h files has these pins reference so that I can change and build.

    sravich1 said:

    you said initially d52_starter.h which I could not find in the BLE_peripheral_App project.

    Yes, I see now that it is rather in /components/boards/PCA10056.h, sorry about that. Do you have issues finding the components/boards/ folder in your SDK? It should be in the root folder.

    or any other Bluettoth terminal App....I get connect and disconnects immediately..how to get this working for any 3rd party App also??..any code changes we need to enable let me know

    Could you expand on this? What are you using to connect?

    Regards,

    I found this ..sure I will try changing pins here

    currently since I am using nRF52840 board..for UART can I use pin 8 and 6 for RX and TXD.???

    currently I am using nRF connect App where I can send and receive..I cannot do  the same using nRF UART2.0 or bluetooth terminal 3rd party App..any reason should I change anything let me know.

    Thanks for your suggestion.

    regards
