Can we have multiply services in the program for BLE applicaiton?

Question

Hi everyone, I have one question shown in the title. I try to add a second service in "ble_app_uart" project (the project is in the SDK for nRF51, SD130 v2), I did not change any code in the original project but only add a new service I learnt in this blog: devzone.nordicsemi.com/.../ 
. Then the program seems just stop and fail to add even one service. It works very well before I add the second service. For a little bit more detail, I put the second service init code in the original services_init() function. And it works with my own service when I bypass the original service.
My board is PCA10028
Any idea?

If you use one or more vendor specific UUIDs you have to inform the Softdevice about it in ble_stack_init(). Have you added: 
 ble_enable_params.common_enable_params.vs_uuid_count = 'number_of_vs_uuids'
 
 When you add UUIDs like this you will most likely have to change the RAM base and start address as well, like shown in the comment section here . Use RTT Viewer or a UART serial terminal to see the debug messages from the Softdevice. If none of this helps, please try to debug like this to pinpoint where and why things go wrong.
