Hi,

Please make sure that you've allocated space for the application context in the device managers config file which used to set the service changed flag (device_manager_cnfg.h-> DEVICE_MANAGER_APP_CONTEXT_SIZE). If it's set to zero you will get an assert that causes a system reset as the application can't set the service changed flag.

If you've already set the DEVICE_MANAGER_APP_CONTEXT_SIZE to more than 4 bytes the reset is caused by something else. Then I'd suggest to attach a debugger and see if app_error.c -> app_error_handler() is reached during program execution, and if it is, read the input arguments to determine the location and cause of the assert.
