Thanks. I got the answer when I check the function of advertising_init(), I found the p_uuid of the 'advdata' variable must be assigned with an array of UUID of services which we want to advertise. So when I change the UUID of service , advdata can not find the original UUID because I did not add it to the stack.So the solution is to change the original UUID to the new UUID in the definition of variable of 'm_adv_uuids', then it works.

put a breakpoint in the app_error_handler and find out which of the APP_ERROR_CHECK() macros failed and why.
