Hi,

It's not implemented. You need to implement your own application code to do so. You need to write code to handle the write command from the phone. And then write that value down into flash. Then write some code to check the value in the flash and if it's not 0xFFFF or the default one, you read the value and use it in your beacon advertising packet.

To learn how to write to flash have a look at the fds example here and the library documentation here.

ok for your information. i just need to change the value of uuid major and minor through mobile app after getting the new values. i want to advertise with those values in advertisement packet. without writing in flash.
