https://devzone.nordicsemi.com/f/nordic-q-a/94295/bluetooth-long-range-with-smartphoneGood Day! I have a Samsung Note 10 smartphone (it supports Long Range) and I want to connect it to an nRF52840 microcontroller using BLE Long Range. What is the approximate maximum connection distance I can expect, assuming I also use the nRF21540en-USTelligent Community 13Mon, 28 Nov 2022 14:33:42 GMThttps://devzone.nordicsemi.com/thread/397917?ContentTypeID=1Mon, 28 Nov 2022 14:33:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:05ff535b-d5b7-4169-bf2c-da316728fbdeKenneth<p>Hi,</p> <p>Range is really difficult to comment on, because there are so many factors that may contribute either way. There was some testing when Bluetooth 5 Long Range support was released:<br /><a href="https://www.nordicsemi.com/News/2019/04/Bluetooth-5-range-put-to-the-test">https://www.nordicsemi.com/News/2019/04/Bluetooth-5-range-put-to-the-test</a>&nbsp;</p> <p>The above was with an nRF52840 in both ends of the link, I am not aware of any specific test with a phone, but since all communication is bidirectional, the max range will be limited by the peer with the lowest output power + the peer with the least sensitivity. So, my only suggestion would be to setup a test that meet your use case and see if it is enough.</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
