This is for a very basic peripheral based on NUS service.

It depends on your application&#39;s requirements you can choose to use the module(s) or not. If you don&#39;t plan to have central role, you can think of using S110, which has smaller flash size (96kB) compare to S130 (108kB).</p> <p>In addition, if your application doesn&#39;t require bonding you can think of not using peer manager at all, and handle the events on your own. You can refer to ble_app_uart to see how we handle events without using peer manager.</p><div style="clear:both;"></div>
