Spikes in data collected with rpi3

From another post where similar problems where found.

in english, otso believes that there could be several programs running that trying to use BT on the RPI and that could in some way create the bad data.

how can I be sure I don’t have several apps using BT, so I could eliminate that possibility for error? I’m no linux guru, in other words no ide how to check that from the console.
