The .NET master could find the device properly, and could communicate with the device to read the thermo data.

Only devices that are either currently connected, previously bonded or advertises a service that is natively supported by iOS (ANCS solicited, HID) will show up in the Bluetooth settings.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/5871?ContentTypeID=1Wed, 08 Jan 2014 04:05:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cab429b6-56c6-4319-8170-925b5b2aa1f6Minghao<p>By doing what you said makes it ok. Actually , iOS would show the BLE device paired after the connection was established.

I&#39;ve often used <a href="https://itunes.apple.com/us/app/lightblue-bluetooth-low-energy/id557428110?mt=8">LightBlue</a> for evaluation purposes, or our <a href="https://itunes.apple.com/us/app/nrfready-utility/id497679111?mt=8">nRF Utility app</a> to actually connect and receive health measurements.</p><div style="clear:both;"></div>
