Hi Neil,
Thanks for your idea.
If I got it right, the BL writes to a certain EEPROM address a known value. The Main application check for this value in that particular EEPROM address, to verify the BL is present.
But, if you reprogramm the flash, using the ISP instead of the BL, the BL will disapear, whilst the EEPROM remains. That leads to a false recognition of the BL being present.
Or do I miss something?
