Merge ble_app_interactive with ble_app_uart example available in SDK 15.2.0

Hi I am working on nRF 52832 and nrf 52840 dongle. I want UART service to be used in my application and application should allow me to scan peripheral devices with user command via Command Line Interface(Putty).
I am trying to merge ble_app_uart and Ble_app_interactive example codes with some modification.

Please suggest me the best way to do it...

  • are you sure you need to merge them? it appear the ble cli app already has the ble_nus service provide. do you know what feature the ble cli app is missing that you need. I would say that should be the first step. Identify what you are missing.

  • Hi thanks for the reply. But how can I prove that it is using Nordic uart service ? Because when I check the ble_app_interactive application it doesn't use ble_nus_c file or functions.

    How can I show that the code has this feature implemented ?

    Please provide me solution

  • Hi Thanks for the Code ..I have modified my according to your suggestion.

    I have one doubt: How to prove that my code has UART service feature.? How to check UART service?

  • Hi, 

    I am interested in the same thing .

    Interactive app that acts as a central ( NUS_C) and can exchange data with peripherals (NUS )  over NUS. 

    I've noticed that in ble_m.c , the "ble_nus_c_evt_handler"  is commented out , so does "ble_nus_chars_received_uart_print" and "db_disc_handler" . 

    why is that ? 

    Thanks, 

    Ran

  • Hi Ran,

    actually my requirement was to act device as both central and peripheral, that is the reason why i commented ble_nus_c_evt_handler which handles events only when device is central.

    but as i see your requirement you want your device to act as central so you use ble_nus_c_evt_handler in your application.

    Thanks
