Thanks a lot mc;
The documentations gave me a good idea to start with.
Please clarify the following queries:
When I am sending binary file from say UART, should I send .bin file or .hex file of the application code?
Should it be interpreted(.bin / .hex) in code and then written to flash ? or should it be written as it is (as generated from IDE) into flash using IAP?

Please Help and guide..!

Thank you ..
