https://devzone.nordicsemi.com/f/nordic-q-a/43932/smartphone-and-beacon-roles-central-peripheralHi, In our project we have got one NRF52 as a central and one as a peripheral. For now we are correctly connecting between our devices - periph is advertising and central is scanning. We want to add new functionality, smarthpone connection insteaden-USTelligent Community 13Sun, 24 Feb 2019 23:18:49 GMThttps://devzone.nordicsemi.com/thread/172662?ContentTypeID=1Sun, 24 Feb 2019 23:18:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2ea42bfb-0393-4c00-a48d-db7b84e66308Simon<p>I don&#39;t think this is possible. Phones are using bluetooth classic by default (as far as I know), and the nRF52 chip does not support this. In order to connect to a scanning nRF52 device, you would need&nbsp;the phone to advertise using the BLE protocol, which can be done through an app.</p> <p>Best regards,</p> <p>Simon</p> <p><strong>Update (02.27.19):</strong></p> <p>It is possible to communicate directly with the phone through the HID service, take a look at <a href="https://devzone.nordicsemi.com/f/nordic-q-a/25351/hid-consumer-control-settings">this</a> case. If you are going to use any other services, you would need an app dedicated for that.</p> [quote user=""]I think it may be a problem because there are probably 2 centrals in this example..[/quote] <p>&nbsp;I think most of the phones support the peripheral role, but you would need an app for that.</p><div style="clear:both;"></div>
