I'm sorry. I don't understand what you mean.

There is only "one" advertising from the beacon (GAP peripheral), and when you connect (as GAP central) to the beacon then you can discover the services (DFU, service to reconfigure tx power, advertising window & interval, ... etc).

should I only start the beacon after a connection has been made

You cannot connect to the beacon if it is not "started"/advertising in the first place.

Is there an option to provide a signal to increase the interval? The idea I had is as following: The sensor advertises on a very low interval 5/10seconds to ocnserve power, but does not provide a beacon. When the user connects to the BLE sensor start a beacon with a high interval and a 1 minute timeout after which the sensor return to its low interval advertising.

What kind of signal? After you have connected? If you advertise with a big interval it could take some time before you are able to connect. Why would you event need to advertise beacon info after you have connected? I'm having trouble understanding, sorry.

Hello Matt,

My application is currently running a GAP peripheral equal to that of the buttonless DFU example. I've not included the beacon in my current project as I had some troubles copying the buttonless DFU example.

My main problem is as following: Should I always have my beacon active on a low interval, as well as advertising an GAP peripheral for DFU and another service for configuring some application settings or should I only start the beacon after a connection has been made to the GAP peripheral or when the settings service receives a command to enable the beacon? What would be the best methode to implement the settings configuration?

My applications purpose is to use an mobilephone app to locate the BLE device within a radius of 20 meter of the device. I'm not developing the phone App, that's done by another thrird party. In order to let the application feel responsive, I would like to have the option to increase the beacon advertising interval when the phone App signals it's looking for this particulair device.

Your beacon sensor is running as a GAP peripheral correct? Once the user (the GAP central) connects to your beacon it won't advertise anymore. Or do I misread your use case description here?
