Splitted 120 seconds UART timeout into chunks of 500ms The UART connection via Bluetooth was realized using a receive call with 120 seconds timeout. By cancellation it seemed for the user as if the connection would have been aborted. In reality the received function keeped executing the wait for RX data till timeout occure. To avaoid this the timeout has been splitted into several calls with 500ms timeout => If the user disconnects by pressing "back" the COMM function is now ended.

User program conditions
The user application to be loaded into the Flash memory using IAP should be built with
these configuration settings:
1. Set the program load address at 0x08003000, using your toolchain linker file
2. Relocate the vector table at address 0x08003000, using the
"NVIC_SetVectorTable"function or the VECT_TAB_OFFSET definition inside the
"system_stm32f10x.c"

can be found here system_stm32f4xx.c
