Hi,

To enable the service changed characteristic you need to set the service_changed flag. You can set the flag in the ble_stack_init() function like this:

ble_enable_params_t ble_enable_params;
err_code = softdevice_enable_get_default_config(NRF_BLE_CENTRAL_LINK_COUNT,
                                                NRF_BLE_PERIPHERAL_LINK_COUNT,
                                                &ble_enable_params);
ble_enable_params.gatts_enable_params.service_changed = 1; \\IS_SRVC_CHANGED_CHARACT_PRESENT
APP_ERROR_CHECK(err_code);

it is complete. thank you.

thanks. I will try it.
