How to update major and minor id for ibeacon using mobile application ?
This question has been asked before.
You will need to modify the beacon application to add a service to write those parameters.
Or probably what would be easier is use another example as a base, which already has a write profile, and add beacon functionality to that.
I have created complete ibeacon firmware based on nrf52 with android app for configuration.github.com/.../ibeacon_nrf52
