I am trying to implement 128 bit uuid service and charachteristic and I am getting error 4(memory error) from
line 10: sd_ble_uuid_vs_add(&m_midi_service, &midi_init);
static void services_init(void)
{
uint32_t err_code;
ble_nus_init_t nus_init;
ble_midi_service_init_t midi_init;
memset(&midi_init, 0, sizeof(midi_init));
midi_init.data_io_write_handler = data_io_write_handler;
err_code = ble_midi_service_init(&m_midi_service, &midi_init);
APP_ERROR_CHECK(err_code);
memset(&nus_init, 0, sizeof(nus_init));
nus_init.data_handler = nus_data_handler;
err_code = ble_nus_init(&m_nus, &nus_init);
APP_ERROR_CHECK(err_code);
}
this is the midi_service code that i am using:

this is the header code:

(of course i include all neccery headers and declare all neccery functions..)
I was googling out the error and find an answare thats modified sdk_config.h file but I don't have it..
I have a file called softdevice_handler.c but I don't understand how to modify it for my needs..
