https://devzone.nordicsemi.com/f/nordic-q-a/11255/gatt-without-bondingHow do I use the NRF51 or 52 to create a GATT server with read only service without requiring bonding? Basically I want to be able to provide more data than advertising allows. Another alternative that would work would be to allow a temporary bondingen-USTelligent Community 13Tue, 12 Jan 2016 09:58:20 GMThttps://devzone.nordicsemi.com/thread/42274?ContentTypeID=1Tue, 12 Jan 2016 09:58:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:90776008-0316-4b1f-bc5d-df02f35a8c3cAnders Strand<p>The Nordic Uart Service Server(<a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk51.v9.0.0%2Fble_sdk_app_nus_eval.html&amp;cp=4_1_0_4_4_17">NUS</a>) example project will be a good starting point. It does not require pairing.</p> <p>Alternatively, you can put data in both the advertisment packet and scan response packet. This will give you a total of 58 bytes.

So just add a service, add read-only characteristic(s) which have open permissions, which is pretty much the default, and you&#39;re done. Anyone can connect and read the data.</p> <p>Most of the simple peripheral examples in the SDK don&#39;t use bonding or pairing, they make open services anyone can use.</p><div style="clear:both;"></div>
