What shall I do to correctly add NUS service?

[mboungou]

Hello, I want to add NUS service on the SDK_14.1.0_1 example called "ble_app_hrs_rscs_relay". I added

    uint32_t       nus_err_code;
	ble_nus_init_t nus_init;
    memset(&nus_init, 0, sizeof(nus_init));
    nus_init.data_handler = nus_data_handler;
    nus_err_code = ble_nus_init(&m_nus, &nus_init);

   in services_init of "main.c".

I set "NRF_SDH_BLE_VS_UUID_COUNT" to 1 in sdk_config.h and I modified RAM start address and size (in the .ld script) according to warning message I received after compliation and exection.

As a result, it compiles and run normally except that I cannot connect the NUS server with the smartphone application. I got "The device does not have the required service". Screenshot_20180109-153605.jpg

and on nRFConnect application, I only see the Heart Rart Service. Screenshot_20180109-153644.jpg What shall I do to correctly add NUS service?

Thanks for support. Here is the main.c, sdk_config.h and .ld script.

The service is initialized but still cannot find it on nRFConnect. And on nRFToolBox it connects and disconnects right after saying "The device does not have the required service". And in the message, I have ble_gatt: sd_ble_gap_data_length_update() (request) on connection 0x0 returned unexpected value 0x13.
