Initialize and use multiple BLE services

Question

I am trying to initialize the BLE NUS UART service and the BLE LBS service so both can be used at the same time in a single nRF52 application. I can initialize a single service without any problems. But if I call the init function for the second service the application hardfaults. Is it possible to initialize two services to run simultaneously? Please advise how I might accomplish this. 
 I am using nRF52 SDK version 14.2 combined with the Mesh SDK version 1.0.1 on an nRF52 development kit. I used the ble_peripheral NUS UART example as the basis. Then I added the LBS service source file to that project and added the lbs init function to the services_init function in the NUS example.

Hi, 
 That is very strange. Can't blame you for assuming it is a hard fault then. It could be a bug in the code though, that calls the hardfault_handler instead of app_error_handler. If it had called the latter you would have seen some error codes as well. I'll try to investigate it. 
 For your next question: It looks like you are trying to fit two VS UUIDs in one advertising packet. Each one is 16 bytes long, a total of 32 bytes. Unfortunately, according to the BLE specification you are only allowed to put 31 bytes in the packet. Please see this thread: https://devzone.nordicsemi.com/f/nordic-q-a/7066/setting-tx_power_level . What you can do is to put one UUID in the advertising packet, and the other one in the scan response packet.

You can change advertising data at any time using sd_ble_gap_adv_data_set () or the Advertising Module API.
