Are there some examples about creating 128bit uuid service?

Hi, all I'm sorry to ask such a simple question, i wanna create a 128bit-uuid service, my code doesn't work. Here is my code:

1. include "mbed.h"
2. include "blecommon.h"
3. include "hw/nRF51822s/nRF51822s.h"

DigitalOut led(P1_5); nRF51822s nrf ( P0_19, P0_18, P1_26, P1_27); /* (tx, rx, rts, cts) */ GattService battService ( 0x180F ); GattCharacteristic battLevel ( 0x2A19, 1, 1, GattCharacteristic::BLE_GATT_CHAR_PROPERTIES_NOTIFY | GattCharacteristic::BLE_GATT_CHAR_PROPERTIES_READ);

uint8_t my_base_uuid[16] = {0,1,0,0,4,5,6,7,8,9,0,0,0,0,4,5}; UUID custom_uuid(my_base_uuid);

GattService myService(my_base_uuid);

int main(void) { led = 0; /* Make sure we get a clean start */ nrf.reset();

/* Add the characteristic to our service */ battService.addCharacteristic(battLevel); myService.addCharacteristic(battLevel);

/* Pass the service into the radio */ nrf.getGattServer().addService(battService);

nrf.getGattServer().addService(myService);

if(myService.primaryServiceID.type) { led = 1; } /* Configure the radio and start advertising with default values */ /* Make sure you've added all of your services before calling this function! */ nrf.getGap().startAdvertising();

/* Now that we're live, update the battery level characteristic */ uint8_t batt = 72; nrf.getGattServer().updateValue(battLevel.handle, (uint8_t*)&batt, sizeof(batt));

while(1); }
