Example ble_app_uart_c generates an interrupt HardFault_Handler

[kxct]

hi,

   Development environment:

   SDK15.2 

   NRF52832_QFAAB0

During the test, the program will enter the HardFault_Handler interrupt. The process of entering the HardFault_Handler interrupt is the memcmp call from the softdevice.

There are about 40 Bluetooth devices around me.

Another problem is to modify the global macro definition __STACK_SIZE, I look at the .map file, the size of the stack has not been changed.

The cause of the problem has been found, there is a problem with the Bluetooth device broadcast data. ble_advdata_search does not have the correct return value, causing the pointer to cross the boundary
