BLE Characteristics configuration at run time

[Armando]

Is it possible to generate a pre compiled library that configure at run-time new BLE services and characteristics on the nRF52840?
If the answer is yes, is it possible to integrate the library into an existing project?

Hi,

we want to develop a library that our customer can use in order to communicate with our Android application. 

We want to build the characteristics, necessary to communicate with our App, into the library. In this way our customers can use the library and don't need to know the characteristcs that they are using.

Is It possibile with nRF52840 and the Nordic Soft devices?

Thank you,

Armando

Hi,

Not sure I understand exactly what you want. But the limiting factor would probably be memory depending on how many services/characteristics you want to support. It's possible to add attributes runtime, but it requires that you have enough flash for the program and also the enough available memory to add them. Since you are also controlling the android part another option would be to upgrade the device from the android phone, having different configurations available on that end.

And example applicaiton could be the Thingy:52, this has several configurations the end user can set up.
