So to clarify, you are using serialization and the application version in question here is that of the serialization code which is running on the nRF51?

Hi run_ar,

Thanks for your reply!

A.) But, I don't know how to obtain the value in application start address + 0x0100. My device is nRF51 serial.

May I follow as below to define application start address + 0x0100 and obtain the application version ? If yes, how can I write back a new application version into the application start address + 0x0100 ?

#define SD_FWID_GET(baseaddr) ((*((uint32_t *) ((baseaddr) + SD_FWID_OFFSET))) & 0xFFFF)    
SD_FWID_GET(MBR_SIZE));

B.) I am working on the heart_rate_collector example code of nrf51-ble-driver_linux_0.5.0. So I program my device to Central device. How can I obtain this application version in heart_rate_collector example code ?

A)For application version handling see here.
B) I suggest you use the device information service for this and populate it using the version from an address as suggested in A.
