If you are having trouble with it you could consider adding a question where you explain what you have done and what you want to achieve.</p> <p><a href="https://devzone.nordicsemi.com/question/43426/strategy-for-long-time-connectivity-over-ble/?answer=43448#post-id-43448">This</a> answer gives a pretty good overview over advertising and connection communication.</p> <p>Both options allows you to send small amounts of information.</p> <p>If you want to pair (Bluetooth context), you need to use connection for communication, or you need to implement your own pairing mechanism on top of the advertising communication.</p> <p>You are not mentioning any real time requirements, or how often you expect to actually send data. Maybe you could try to edit your question to include some more information, and I can try to give a more specific answer.</p><div style="clear:both;"></div>
