Hi

The custom BLE service example, made by one of my colleagues, is a great tutorial to a multitude of functions, including reading characteristics from various devices/apps. Please check it out, and don't hesitate to ask if you have any questions.

Best regards,

Note that this has nothing to do with Nordic or nRF52840!

The whole point of standards like BLE is that their are completely independent of the underlying hardware.

So the place to go is to the Android developer documentation:

I don't see anything in that tutorial about the Android side - which seems to be what Nahom is asking ?

I assume he just wants to read characteristics data from an Android phone, and the example explains how to do that (using nRFConnect). Sorry if that's not what you're after Nahom.

Is it just me, or can you also not "@ mention" @Nahom ?

ie, the forum does not automatically make that into a link?
