Hi, 

Have you flashed the bootloader ? Please note that you still need the bootloader after you add the buttonless service to your project. 

Have you increased the NRF_SDH_BLE_VS_UUID_COUNT in your sdk_config.h file ? You need to increase it by one if you add the DFU buttonless  into your ble_app_uart.

Hi Murugan, 

Here is an example I made for SDK v15.0. It combine ble_app_uart with the buttonless service. Only Keil is supported.
